Wickramasinghe, G. L. D. "Steam-jet intermingled sewing threads." Thesis, University of Manchester, 2003. http://ethos.bl.uk/OrderDetails.do?uin=uk.bl.ethos.601663.
Full textAbstract:
The object of the work was to develop the use of high-pressure steam in order to replace air in air-jets in the production of intermingled yarns, particularly for sewmg threads. The thesis discusses the development of air-jet texturing! intermingling and analysis of the process by earlier workers. Differences between steam-flow and air-flow through jets are discussed. The effects of process parameters on steam-jet intermingling and comparisons of steam-jet intermingled yarns and air-jet intermingled yarns have been studied. The results show that steam-jet intermingled yarn has higher strength, higher elongation, higher loop stability and lower boiling water shrinkage than air-jet intermingled yarn. Core-yarn wetting does not have a significant effect on the steam-jet intermingling process and intermingled yarn properties. Elimination of the wetting system reduces the production cost of steam-jet compared to air-jet. Steam-jet intermingled yarn needs less energy to heat-set after intermingling, as it has been partially heat-set by steam during intermingling. Sewing threads were made from steam-jet intermingled yarns and assessed using industrial sewing specifications. The sewing threads were also subjected to commercial trials. Sewing test results show that steam-jet intermingled sewing thread meets commercial levels of performance. Preliminary investigations revealed that high-pressure water could also be used in intermingling as a replacement of air or steam. It was found that lower core-yarn overfeeds, such as 2.9 %, can be used and therefore higher strength of intermingled yarn could be achieved. Turbulence in water was improved by designing a jet so as to suck air by water through a capillary from the outside atmosphere.

Chmielowiec, Ryszard. "Sewing machine, fabric and thread dynamics." Thesis, University of Leeds, 1993. http://etheses.whiterose.ac.uk/4045/.
Full textAbstract:
In recent years, sewing technology has witnessed dramatic increases in machines speeds, new types of materials, new sewing threads and evaluation methods – but the principal type of sewing machine remains the lockstitch type and this is likely to remain the most common and versatile for the foreseeable future, particularly for sewing woven fabrics. Sewing machine speed increases lead to a loss of control of the sewing process due largely to an increase of the dynamic forces and consequently to problems such as seam pucker. In this research computer-based instrumentation and high-speed digital image and signal acquisition systems were developed to study the dynamic effects of the sewing machine, fabric and thread on seam pucker. Needle thread tension, needle bar pressure/tension, presser-foot pressure and displacement signals were acquired simultaneously by 4 strain-gage/piezo-quartz sensors mounted on a Pfaff-563 machine and results were related to pucker measured by a CCO colour-video camera system integrated with the sewing machine. A series of experiments conducted on various types of fabrics provided illustrative examples of the characteristics of each signal acquired (distinctive shape, amplitudes-peaks valleys locations, duration etc), and also enabled their characteristics to be compared and the interactions among the signals to be studied. For example it was found that the increases in magnitude of the dynamic forces in relation to sewing machine speed increases from 200rpm to 5500rpm were lower than expected (needle thread tension 2.6 fold, presser-foot 1.2 fold and needle penetration force 3.2 fold). A comparison of the needle thread tension for standard woven fabrics and micro-fibre fabrics showed a significant difference in the signal shape, location and amplitudes. The instrumentation developed is located at the Institute of Textiles and Clothing of the Hong Kong Polytechnic University in Hong Kong.

Chatterley, James J. "Sound Quality Analysis of Sewing Machines." BYU ScholarsArchive, 2005. https://scholarsarchive.byu.edu/etd/424.
Full textAbstract:
Sound quality analysis is a tool designed to help determine customer preferences, which can be used to help the designer improve product quality. Many industries desire to know how the consuming public perceives their product, as this affects the product life and success. This research investigates which of the six sewing machines provided by Viking Sewing Machine Group (VSM group) consumers find most acoustically appealing. The sound quality analysis methods used include both jury based listening tests and quantitative sound quality metrics from empirical equations. The results from both methods are completely independent and are shown to have a very strong correlation. The procedures and results of both methods, jury listening tests and mathematical metrics, are presented. Near field sound intensity scans identified acoustic hot spots and give direction for possible design modifications to improve the acoustic signature of the two top tier machines, the Designer 1 and Creative 2144 (Husqvarna Viking and Pfaff respectively). This research determined that the entry level Pfaff Select 1530 has the most acoustically appealing sound of the six machines evaluated. In addition, it was also determined that a reduction in the higher frequency sounds produced by the machines is preferred over a reduction in the lower frequency sounds. Further investigations, including an evaluation of machine isolation and startup sounds, were also performed. The machine isolation results are highly dependant on the individual machine being evaluated and would require independent evaluation. In the machine startup sound assessment, it was discovered that again the Pfaff Select 1530 has the preferred sound. Near field acoustic intensity scans provide additional information on locations of strong acoustic radiation. The near field scans provided valuable design information. The acoustic "hot" spots were discovered to exist in the lower portions of the machines near the main stepper motor in the Designer 1, and radiating from the bottom plate of the machine in the Pfaff Creative 2144. This analysis has led to various design modifications that could be implemented to improve the sound quality of the machines, specifically the Designer 1 and the Creative 2144.

Full textAbstract:
I intend, with this thesis, to investigate how Michel Foucault's concept of ???a positive unconscious of knowledge??? can be illustrated by overlapping narrative segments. I have coined the term ???friction???, as a writing practice, to describe the space in-between narrative conception and conscious, ordered reflection upon that narrative. Thus, the thesis comprises an exploration of Foucault's intersecting marginal zone, which is an integral aspect of his philosophic concept of ???positive unconscious???. The ???positive unconscious??? is where the overlapping sections of what Foucault calls, a ???table??? (creative narrative) and ???tabula??? (the ordering of the narrative) are situated. The frictional form is synonymous with Foucault's concept. It is as a developing narrative conception that becomes an ordered practice, and also aims to be what Jacques Derrida calls ???a new writing???. Hence, Foucault's ???positive unconscious???, Derrida's ???new writing???, and the frictional narrative process all comprise, along with and through the multiple inclusions of myriad theorists, philosophers, fiction writers, lyric poets, etc., an amalgamated whole ???new??? narrative (the frictionalised thesis). The paradox of the ???new??? (frictional) narrative is that through mimesis comes characterised difference - a ???new??? hybridised space is opened up which both fascinates and appals, railing as it does against fixed, constraining and systematised linguistic and discursive structures. Yet this is a stimulating space that ultimately brings new focus to stifling self-conformity. It is a frictional space comprised of a profusion of literary ???voices??? made singular, a singularity that is also mutiplicitous in its composite origin. It is a frictional observance that refutes the injunction of needing definite closure given its inclusion of potentially unlimited sources.

Full textAbstract:
To avoid high costs and delays, it is important to correct mistakes and to solve problems as early as possible in the development process. The aim for this master thesis is to develop dynamic models to describe the mechanical motions in an advanced sewing machine. The main purpose is to develop a mathematical model which can be connected with the development tools used by VSM Group. The starting point for the simulation of mechanical motions in the sewing machine has been that the in-signal to the model is the electric in-signal to the main motor [V] and that the out-signals are the arm shaft motions [position, velocity and acceleration]. There are significant friction variances depending on the arm shaft position during one cycle (one arm shaft revolution). The variation of the friction measurements have been implemented in two Simulink models, one that has been converted from the CAD model and one that is based on equations for an electric-motor. The model based on the electric-motor is the most accurate model because the model is less complex than the CAD converted model. The sewing machine contains several stepper motors. VSM Group wish to develop mathematical models also for the stepper motors. Two Simulink models have been developed, one with the aid of Matlab toolbox and one based on mathematical and physical relationships. The velocity of the sewing machine fluctuates from time to time depending on the temperature and lubrication. The temperature impact has not been included in these models. To compensate this, models for a warm and a cold machine have been developed.För att undvika höga kostnader och förseningar är det viktigt att rätta fel och lösa problem så tidigt som möjligt under utvecklingsprocessen. Målet med detta examens arbete är att utveckla en dynamisk modell som beskriver de mekaniska rörelserna i en avancerad symaskin. Det huvudsakliga syftet är att utveckla en matematisk modell som kan sammankopplas med de övriga verktygen som används hos VSM Group. Utgångspunkt för simuleringen av de mekaniska delarna har varit att insignalen till modellen är den elektriska insignalen till el-motorn [V] och att utsignalerna är rörelsen på arm axeln [position, hastighet och acceleration]. Det är stora skillnader i friktionen beroende på i vilket läge armaxeln befinner sig i under en cykel (ett varv på symaskinens arm axel). Detta har studerats genom att mätningar på symaskinen har gjorts. Dessa friktionsmätningar har implementerats i två simulink modeller, en som konverterats ifrån CAD modellen av symaskinen och en modell som utgår ifrån ekvationer för en elmotor. En mer tillförlitlig modell fås från modellen utifrån elmotorn, eftersom den är mindre komplex. Symaskinen innehåller också många stegmotorer. VSM Group önskar också modeller för dessa. Två simulink modeller har tagits fram en med hjälp av matlab toolbox och en baserad på matematiska och fysikaliska samband. Symaskinens hastighet varierar något från gång till gång, beroende på temperatur och smörjning. Temperaturfaktorn har inte tagits med i dessa modeller. För att kompensera detta har modeller för varm respektive kall maskin tagits fram.

Cesare, Carla. "Sewing the self : needlework, femininity and domesticity in interwar Britain." Thesis, Northumbria University, 2012. http://nrl.northumbria.ac.uk/14736/.
Full textAbstract:
This thesis looks at design practice as a method of investigating the relationship between design and identity in interwar Britain; in particular it considers design from the perspective of practice, not solely as the final object or the story of the maker. For it is in the process of making that the varied aspects of design as it is practiced are configured to create the greatest impact on everyday life. This research proposes that the quest to construct one’s identity, in particular a feminine identity, can be demonstrated by the making of goods and objects through the traditionally feminine practice of sewing and needlework, specifically those made at home. It argues that home sewing, as an understudied everyday practice, was intrinsically bound up with ideas of who women were, how they imagined themselves, and how their feminine identities were represented. Between the wars, home-sewing was an integral daily practice for middle-class women that left indelible memories of not only the items made, but of specific types of sewing and design practice, who it was made for and how it was used. It also explores these specific practices during a period of enormous change- culturally, technologically and politically – and particularly important for this study are the themes of femininity and domesticity, as well as the boundaries of private and public life in relation to modernity. Methodologically it focuses on sewing practices by utilizing mass media, specific objects and oral histories to elucidate this. This thesis considers the breadth and extent of home sewing as an everyday practice aligning individual narratives, original source material and theoretical analysis.

Piasecka, Michelle. "Sewing shadows : investigating performance research in the primary school curriculum." Thesis, Manchester Metropolitan University, 2012. http://e-space.mmu.ac.uk/347081/.
Full textAbstract:
This thesis recounts the development through fieldwork in primary schools of a distinctive performance pedagogy that bridges drama and live art. Two inter-connected strands run through the thesis. First, a praxis in the context of the primary school curriculum involves the creation of learning spaces through performance work which embrace qualities of ownership and subjectivity within imaginative and participatory practices. This prompted a shift from live art to more conventional drama praxis and has special benefits for disadvantaged and marginalised children. Historically, the thesis sits within Buckingham and Jones (2001) description of the “cultural turn” towards the creative industries. In the years following New Labour’s election victory (1997) a number of influential documents and directives were launched to promote creative learning in schools. The creative agenda emerged at a time when teachers experienced unprecedented levels of control over, and public scrutiny of, their everyday working lives; it was a period dominated by a “bureaucratisation” of education. I have positioned practice in the midst of reform, which at times appeared to be pulling in opposite directions. Secondly, a conceptual framework examines the “crisis of representation” (Denzin, 1997) in relation to lived experience and the written word. Writing often fails to capture the ephemeral nature of the performance studies agenda. In performance, meaning is found in the moments between thought and expression and in the silence between words. But, whilst words cannot replicate reality, writing can offer a deep and long-lasting impression of the world we inhabit. In response to the crisis of representation the thesis works towards a polyphonous account of the research process, weaving between performance texts, narrative stories, diary entries and the writing of others. Poststructural and phenomenological perspectives have illuminated the shifting space between competing discourses and ways of seeing. Above all, this thesis is the product of work with children, made possible when the desire to imagine outweighs the reality and actuality of the present.

Full textAbstract:
In this dissertation, we develop two related problems in the nonlinear functional analysis. The first is the analyticity of the Cauchy singular integral in Schauder spaces which is motivated by the second problem, namely the perturbation analysis of the conformal sewing problem in Schauder and Roumieu spaces. In Chapter II, we consider the Cauchy singular integral
f (t)φ0 (t) f ◦ φ(−1) (ξ)
1 1
C[φ, f ]( · ) ≡ p. v. dt = p. v. dξ
2πi ∂D φ(t) − φ(·) 2πi φ ξ − φ(·)
where the oriented simple closed curve φ and the density function f are both defined on the counterclockwise oriented boundary ∂D of the plane unit disk D. Although the linear operator C[φ, ·], for a fixed φ, and the numerical computation of C[φ, f ] have been extensively studied for the last century, in view to several applications to integral equations and boundary value problems (cf. e.g. Muskhelishvili (1953) and Gakhov (1966)), the analysis of the nonlinear functional dependence of C[φ, f ] upon both its arguments seems to be a subject analyzed only more recently (see Introduction Ch. II). This new subject of research finds application in the nonlinear problems of perturbation nature which involve the Cauchy singular integral. In Chapter II we extend the analyticity result for the operator C[·, ·] of Coifman & Meyer (1983b) to a Schauder spaces setting. We assume that both φ and f belong to a Schauder space, say C∗m,α (∂D, C), of complex-valued function of class C m,α on ∂D, with m a positive natural number and α ∈ ]0, 1[. As it is well-known, under such conditions on φ and f , the function C[φ, f ](·) is also of class C m,α . By proving the unique solvability of a boundary value problem of elliptic nature in D and by applying Implicit Function Theorem to a suitable functional equation, we show the real analyticity of C[·, ·]. Then we show the complex analyticity of C[·, ·] and we compute all its differentials. This result of Lanza & Preciso (1998) will be applied in the second part of this dissertation and in another perturbation problem associated to a nonlinear integral equation (cf. Lanza & Rogosin (1997)). In Chapter III, we introduce the conformal sewing problem associated to a shift φ of ∂D, i.e. a homeomorphism of ∂D to itself. It consists in finding a pair of conformal functions (F, G) defined in D and C \ cl D, respectively, such that their continuous extensions to cl D e C \ D, Fe and G e respectively, satisfy Fe(φ(t)) = G(t) for all t ∈ ∂D. A simple normalization condition and well-known results ensure that the sewing problem associated to φ has a unique solution (F, G) and we denote by (F [·], G[·]) the pair of operators which maps φ to the trace on ∂D of such solution. The regularity properties of the operators F [φ] and G[φ] in spaces of regular functions can be used in the study of Teichmüller spaces, which constitute an important subject in geometric function theory (see Nag (1996)). Our aim is to find natural Banach spaces of regular functions where to obtain the analyticity of F [·] and G[·]. First we study the regularity of such operators in Schauder spaces C∗m,α (∂D, C), with m ≥ 1, α ∈ ]0, 1[. By using the classical integral equation approach to the sewing problem, we show that G[φ] and F [φ] = G[φ] ◦ φ(−1) belong to C∗m,α (∂D, C) when φ belongs to C∗m,α (∂D, C). In this setting, by using the analyticity of the Cauchy singular integral (cf. Ch. II) and by applying Implicit Function Theorem to a suitable integral equation, we show that G[·] extends to a complex analytic operator. Then we prove that this Schauder spaces setting is not sufficient in order to obtain an analytic extension of the operator F [·]. Indeed a natural assumption in order to have F [·] analytic, is that φ belongs to a space of real analytic functions of ∂D to C. In Chapter IV we introduce Banach spaces of real analytic functions, namely the Roumieu spaces associated to the differentiation operator. In this setting we show that G[·] and F [·] can be extended to complex analytic operators by employing the regularity results on the composition and on the inversion operator of Lanza (1994 and 1996b).

Fashion is the second most polluting industry and accounts for 10% of global carbon emissions. Consuming fossil fuel based electricity, the primary source of energy in the apparel production process, causes a great deal of greenhouse gas (GHG) emissions. Due to ever-increasing apparel demand and population growth, this industry’s carbon footprint will only grow bigger. As attention on sustainability issues in our world intensifies, research on environmental sustainability in the apparel manufacturing industry is needed. The purpose of this exploratory study was to investigate energy consumption (EC) of the apparel sewing process. The objectives are to (a) identify the most influential EC factors and develop a model to capture EC levels, (b) determine factor interrelationships, (c) identify steps to reduce EC, and (d) explore experts' level of concern regarding EC of the apparel manufacturing and its contribution to greenhouse gas emissions and climate change. A mixed method research study was employed in this study: a qualitative method was utilized to assess expert perceptions and a quantitative method was used to measure EC and build a regression model. This study determined dominant EC and GHG emissions factors from sewing process so that apparel manufacturers can understand which factors need to be controlled to reduce environmental damage. Findings from the study indicated sewing machine motor capacity, sewing speed, and standard allocated minute (SAM) were the most influential EC factors, and shortening the sewing time was found as the best solution to reduce energy consumption in the apparel sewing process. The energy consumption model was found as: Log (EC) = 9.283 + 0.771* log (SAM) + 0.386*knit fabric type + 0.260*sportswear fabric type + 0.080*SPI - 0.008*capacity + 0.004*seam length - 0.001* speed + 0.495. The EC model along with GHG calculator (a tool to convert GHG from EC) will help the industry to determine their EC and GHG emissions level to boost their awareness and to encourage greater impetus for environmental actions. Finally, this study will help designers, retailers, and consumers to pursue environmentally friendly actions in terms of decisions regarding apparel design, sourcing, and purchasing.

Stylios, George. "A study of problems associated with fabric sewing in commercial garment manufacture." Thesis, University of Leeds, 1987. http://etheses.whiterose.ac.uk/5387/.
Full textAbstract:
This thesis reports the results of a study of problems associated with fabric sewing, such as seam pucker and sewing damage, in commercial garment manufacture. Part 1 continues previous work by the author on seam pucker in structurally jammed fabrics; in particular it has been shown that initial Young's modulus of a fabric is a measure of the ability of the fabric to accommodate compressive forces during sewing. This result provides an additional means of predicting the tendency of a fabric to exhibit seam pucker. The static mechanism of seam pucker proposed previously, based upon the relative magnitudes of bending stiffness of thread and fabric, has been revised by establishing that sewing machine dynamics and pucker are closely related. It has been shown that presser foot bouncing in particular induces pucker and that the sewing thread needs to be positively controlled during stitch formation. These results were verified by simple experimental methods, suggesting that modifications to the sewing machine are needed. Such modifications are beyond the scope of this work. Following the earlier static mechanism of seam pucker, it has been shown that seam pucker in fabrics is reduced significantly when the bending stiffness and extensibility of the sewing thread is reduced. In addition seam pucker can be eliminated by improving fabric stiffness locally along the seam area, by incorporating a stiffening material in the seam; this is based upon the technique of pucker elimination found in the author's previous work. In this study this technique is implemented with considerable success in other types of seams and commercially available stiffening materials have been selected. Part 2 investigates sewing damage to fabrics due to sewing needle penetration. Preliminary studies suggested the need for a reliable testing facility. This was made by instrumenting an industrial overlock sewing machine. The instrumentation was based on measuring the force which is exerted by the sewing needle when penetrating the fabric. The testing facility consists of the sewing machine with a strain gauged sewing needle and plate, and a shaft encoder for stitch marking, which with proper signal amplification and conditioning could be fed to a transient recorder and osciloscope for signal capturing and plotting. Investigations with fabrics revealed that the magnitude of the peak force of each stitch cycle can be related to the degree of sewing damage in the fabric. Based on these results the most important variables in sewing damage were fabric softening and its effective application during finishing, and sewing needle size. Studies of sewing damage under dynamic conditions have shown that sewing damage is a frictional problem between yarns in the fabric and between yarns and the metal of the sewing needle, foot, plate and feed dog. The size of the needle plate of the sewing machine seems to affect the degree of damage and fabric "flagging" during sewing damage has been experienced. Finally in the latter section of this study a prototype routine sewing damage tester has been developed and each stage of its development is described. This tester is based on an instrumented overlock sewing machine, which is interfaced with an IBM PC for computerised data capture and analysis in real time.

Full textAbstract:
This thesis concerns the development of a robotic cell to perform assembly and handling operations on cloth.- A flexible automation approach was adopted, in which the robot was required to control the cloth panel during both handling and sewing operations, without the aid of hard automation attachments which might limit the flexibility of the system. The cell consisted of an adaptively controlled robot, a hierarchy of controllers, a conventional sewing machine, a two-fingered fabric steering end-effector, and several sensor systems. A technique was developed for producing a seam parallel to an edge of arbitrary contour, in which two cameras, a cloth tension sensor and the sewing machine's shaft encoder provided the sensory input. Two sensory servo control systems were required, one control system generated the robot's trajectory to maintain a small constant cloth tension, and the other directed the robot to manipulate the cloth panel to maintain a constant seam width. The design of the cloth tension control was based on the measured frequency response of the open loop system. The seam width control was designed using simulation studies, which accounted for the control transfer function, and nonlinearities such as camera pixel resolution, time delays and robot motion limitations. Several robotic handling techniques were developed, so that a cloth panel placed arbitrarily on the sewing table could be set up for an edge seaming operation, and the cloth could be rotated about the needle. The system's flexibility was demonstrated in the assembly of an irregularly shaped cloth panel, in which three adjacent sides were sewn up.

Mulheres e escravos não tinham acesso à educação formal nos Estados Unidos no século XIX. Por outro lado, costurar era uma atividade obrigatória até mesmo para meninas da mais tenra infância. O exercício da costura proporcionava também resultados subjetivos, sendo prescrito para acalmar as mulheres quando se irritavam com os deveres domésticos. No entanto, as mulheres transformaram o peso das obrigações em oportunidade. Enquanto se encontravam para fazer quilts, elas se fortaleciam como grupo, discutindo tanto assuntos domésticos quanto públicos, como a confecção de uma colcha de núpcias ou o direito das mulheres ao voto. Assim, elas encontraram nas agulhas o meio de expressão negado na leitura e na escrita. À época do bicentenário da independência dos Estados Unidos, os quilts foram redescobertos pelos historiadores e pelo mundo da arte, e adquiriram o status de arte. O passo seguinte foi a descoberta da relação entre quilts e a escrita feminina, bem como a aplicabilidade dos quilts como metáfora da textualidade. Na segunda metade do século XX, o movimento feminista foi criticado por não contemplar as necessidades de todas as mulheres, mas dirigir-se a um grupo específico: mulheres brancas, da classe média e com educação formal. Em resposta, surgiu o conceito de interseccionalidade. Com relação à arte, Alice Walker tem abordado a questão da criatividade das mulheres negras nas gerações anteriores ao indagar como elas mantiveram viva a criatividade sem ler e escrever, e sem ter consciência da própria criatividade. As narrativas de Walker analisadas neste trabalho, The Color Purple e "Everyday Use", tratam a costura e o fazer quilts principalmente como atividades favoráveis ao fortalecimento dos relacionamentos interpessoais. Além disso, considera-se que essas atividades constituem instrumentos de expressão que contribuem para a descoberta da criatividade, das subjetividades e das identidades das personagens, e consequentemente, de seus respectivos processos de emancipação.
Abstract: Women and slaves had no access to writing or reading in the United States in the nineteenth century. However, sewing was a mandatory activity even for very young girls. More than bedcovers, sewing also provided subjective results, being prescribed to compose women when they got irritated with their duties in domestic life. However, women turned the burden of duty into opportunity. While they met to quilt, they grew stronger as a group. They discussed domestic as well as public issues, ranging from the confection of a bridal quilt to women's suffrage. Then, they found in their needles the medium for the expression they lacked in writing and reading. At the event of the Independence Bicentennial, quilts were rediscovered by historians and the art world, and acquired status of art. The next step was the discovery of the relationship between quilting and women's writing, as well as its applicability as a metaphor for textuality. Together with the rediscovery of quilts, the feminist movement in the second half of the twentieth century was criticized for not addressing all women's needs, being directed to a specific group: white, middle class, educated women. As a response, the concept of intersectionality emerged. Concerning art, Alice Walker has approached the issue of creativity of black women in the previous generations by asking how they could keep alive their creativity, once they could not read or write. Walker also states that these black women were not aware of their own creativity. Alice Walker's The Color Purple and "Everyday Use" analyzed in this research deal mainly with sewing and quilting as a favorable circumstance for the strengthening of interpersonal relationships. Also sewing and quilting act as instruments for the discovery and expression of the characters' own creativity and identity, and consequently, for their emancipation.

Full textAbstract:
This case study explored the lived experiences of 8 participants in a microfinance sewing program in El Salvador. Numerous studies focused on empowering women by employing microfinance projects or programs in many countries; however, a lack of empirical data exists regarding Salvadoran women's perceptions about how a sewing program with teamwork affects women's empowerment. The purpose of this case study was to understand the women's personal stories, their obstacles as well as any factors they saw as empowering them. Guided by a constructionist framework, a sample of 8 participants: 5 who were sewing students and 3 who were employees, who shared their administrative perspectives about participants' skills, data collection and data analysis methods gained. Five themes emerged from the women's interviews about their sewing program experience: (a) program effect on women's well-being; (b) gained a means of income; (c) increased self-efficacy, confidence, and security; (d) worked in groups or teams; and (e) the teacher's positive influence. The 5 sewing student participants reported they developed self-efficacy and self-fulfillment in the sewing program. The women attributed their success to the teacher, who taught them sewing skills and provided guidance and encouragement. This study contributes to social change by providing insight for additional women's studies on women's empowerment, social work with families and children, and for MSW social work students.

Full textAbstract:
Historically, the construction, alteration, and mending of clothing was provided through household production activities, free of charge by the female members of the household or members of the extended family. These practices have changed in some families because of societal and cultural changes such as the increasing number of women who are employed outside of the household. Apparel construction, alteration, and mending are now available for purchase from service providers in the marketplace. Thus the overall purpose of this research was to examine the nature and foundation of the nonnative influences and attitudes of a sample of employed women toward purchasing apparel sewing services.
Ajzen and Fishbein's (1980) reasoned action model which theorizes four stable relationships provided the theoretical framework for the research. The four relationships were Behavior-Intention (BI}, Attitude-Subjective Norm-Intention (ASNI), Behavioral Beliefs-Attitude (BBA), and Normative Beliefs-Subjective Norm (NBSN). Four corresponding objectives were investigated for three sewing services, clothing construction, alteration, and mending. A fifth objective for each apparel sewing service was used to explore the possible associations among a set of external variables and the employed women's estimated attitudes, estimated subjective norms, and the relative weights of the attitudinal and normative components in the ASNI relationship.
Questions to measure behaviors, intentions to purchase, attitudes, behavioral beliefs, subjective norms, and normative beliefs were developed according to Ajzen and Fishbein's (1980) guidelines. Additional questions were developed to assess fourteen external variables derived from the review of literature. Two thousand ninety two questionnaires were sent through Virginia Tech's campus mail; 657 (97%) of the 679 (32%) returned were useable for the study.
Kendall's Tau testing resulted in significant positive BBA relationships for all three sewing services. Multiple regression testing resulted in significant positive ASNI relationships for all sewing services. Significant positive BBA and NBSN relationships resulted from Pearson Product Moment Correlations for all three sewing services. All four null hypotheses for all three sewing services were rejected and the research hypotheses were supported.
The fifth objective was investigated through three null hypothesis for each sewing service; each null hypothesis was tested with each external variable. The external variable, knowing someone who sews for pay, yielded statistically significant results for all three sewing services in the F-tests for the overall regressions, analysis of variance, and in the Tukey' s post hoc test; however this variable did not lead to significant differences in the standardized betas for services of altering and mending clothes, according to the Chow tests. No other external variables had as many significant tests for all three sewing services as knowing someone who sews for pay had, even though there were other significant tests in some of the relationships tested.Ph.

Full textAbstract:
The gokan is a medium of pre-modern Japanese literature where the story is told through a mixture of text and image on every page, with the narrative and dialogue of the story surrounding the image illustrations on all sides. The Nise Murasaki inaka Genji (A Rustic Genji by a Fake Murasaki, 1829-42), written by Ryutei Tanehiko (1783-1842) and illustrated by Utagawa Kunisada (1786-1865), was one of the most popular gokan of the Edo Period (1605-1868) and has been republished approximately twenty-four times from the end of the nineteenth century until today. By examining how these works handle text and image, this thesis seeks to gain a deeper understanding about how image functions in the gokan genre. When text must be translated and the image altered from the original layout to make it comprehensible to modern readers, the resulting text and image combinations, or lack of image, offer insight into the importance of the role of image in gokan.

Previous issue date: 2010-11-19The central research question is related to the activities of the seamstresses, sewing women in Divinópolis, MG, whose work is considered a domestic order, a natural aptitude and subject to lower wages. However, by sewing, women ensure the maintenance of home and family, break down stigma in relation to paid work and their role in society. One of the main objectives would be to show that sewing women who are in clothing industries or subcontracting for sewing services, play an important role in the process of economic development of the town, one of the poles of clothing production in the country. To write this dissertation were analyzed published reports in newspapers from the town and nearby region. Apart from written sources, there were made twelve interviews with a group of seamstresses who work in the clothing industry and others who worked in their homes, the professionals who work with subcontracting for sewing services. The collapse of the steel industry in the town and region in 1960 was one of the factors that contributed to women taking over leadership of the economy, trying to reverse the disastrous situation. Considering the situation of many unemployed men, women become visible in the job market through the sewing know-how that was successfully passed from generation to generation. The conquest of women barely changes its position inside and outside their homes. Besides there is a sexual division of labor unfairly and unequally, which still claims that women are responsible for almost all tasks and household chores
A questão central da pesquisa se relaciona às atividades das costureiras em Divinópolis, MG, cujo trabalho é considerado de ordem doméstica, uma aptidão natural e está sujeito a remunerações inferiores. No entanto, através da costura, as mulheres garantem a manutenção da casa e da família, rompem estigmas em relação ao trabalho assalariado e ao papel delas na sociedade. Um dos principais objetivos seria mostrar que as mulheres costureiras, que estão nas indústrias de confecções ou facções, desempenham um papel importante no processo de desenvolvimento econômico da cidade, um dos polos de confecção do país. Para escrever esta dissertação foram analisados jornais e relatórios publicados na cidade e região. Além das fontes escritas, foram realizadas, doze entrevistas com um grupo de costureiras, que trabalham na indústria de confecção e outras que trabalhavam em suas casas, nas chamadas facções. A quebra do setor siderúrgico na cidade e região nos anos de 1960 foi um dos fatores que colaborou para que as mulheres assumissem a liderança da economia, tentando reverter a situação desastrosa. Com os homens desempregados, as mulheres se tornam visíveis no mercado de emprego através do saber fazer que foi passado de gerações a gerações com êxito através da costura. A conquista das mulheres pouco modifica a sua posição dentro e fora das suas casas. Além de ocorrer uma divisão sexual do trabalho de forma injusta e desigual, ainda cabe às mulheres a responsabilidade quase exclusiva, das tarefas e atividades domésticas

This study was an historical garment study that investigated the similarities and differences between variables for thread characteristics, such as thread configuration, degree of twist, direction of twist, color, and color match grades of sewing thread used in assembling American women's dresses and suits during the time period between 1880 and 1909. Items were selected using a convenience sampling from the Smithsonian Institution, National Museum of American History, in Washington, DC, and The Valentine Museum in Richmond, Virginia. A total of 417 observations were collected from 39 garments. Noninvasive procedures were used to examine late nineteenth and early twentieth century garments and record sewing thread characteristics from multiple designated locations. Research objectives of the study included: 1) documentation of thread characteristics for machine-sewn seams, 2) documentation of thread characteristics for handsewn seams or stitchings, and 3) documentation of dominant thread characteristics by five year periods.
Frequency distributions and frequency distribution tables were completed. The results of this study revealed widespread use of one basic type of sewing thread for the total sample during the time period 1880-1909. Characteristics of threads used in handsewn and machine-sewn seams or stitchings were 3/2-cord thread with high degree of twist and S direction of twist. It appeared that aesthetic concerns for color differences and matching contrasts of thread with the fashion fabric did not always coincide with use of threads with high strength.
Data analyses revealed recurring patterns. Results found for year to year observations were consistent with results found within the five year group increments. Dominant thread characteristics found within the group observations for chain stitch thread characteristics were also present in the lockstitch group observations and machine-sewn group observations. Patterns noted in observations for handsewn seams or stitchings were also similar to those found in machine-sewn seams.
Noninvasive methods were used for collection of data during the study. Methods used included naked-eye visual observations and hand-held microscope observations for recording seam, stitch, and thread characteristics.Master of Science

Full textAbstract:
abstract: For the past few decades, feminist researchers have worked tirelessly to recover the history of American women’s sewing – both the artifacts made and the processes, practices, and identities linked to the objects produced. With the transition to the digital age, women are still sewing, but they are inventing, making, and distributing sewn objects using platforms and pathways online to share knowledge, showcase their handicrafts, and sell their wares. This dissertation examines contemporary sewing and asks how digital practices are extending and transforming the history of women’s sewing in America. I place my findings against the backdrop of women’s history by recounting how and why women sewed in previous eras. This dissertation demonstrates how past sewing practices are being repeated, remixed, and reimagined as women meet to sew, socialize, and collaborate on the web.
The overall approach to this project is ethnographic in nature, in that I collected data by participating alongside my female subjects in the online settings they frequent to read about, write about, and discuss sewing, including blogs, email, and various social media sites. From these interactions, I provide case studies that illuminate my findings on how women share sewing knowledge and products in digital spaces. Specifically, I look at how women are using digital tools to learn and teach sewing, to sew for activist purposes, and to pursue entrepreneurship. My findings show that sewing continues to be a highly social activity for women, although collaboration and socializing often happen from geographically distanced locations and are enabled by online communication. Seamstresses wanting to provide sewing instruction are able to archive their knowledge electronically and disperse it widely, and those learning to sew can access this knowledge by navigating paths through a plethora of digital resources. Activists are able to recruit more widely when seeking participants for their causes and can send handmade goods to people in need around the globe. Although gender biases continue to plague working women, the internet provides new opportunities for female entrepreneurship and allows women to profit from their sewing skills.Dissertation/Thesis

The concept comes from my life experience, which is inspired by the situation of my stuffed closet. From the connection between my life and old clothes, I start to mend concentrically these second-hand clothes as a symbol of both inside soul and outside body. Through a time-consuming process of hand sewing, I could develop an own spiritual practice to enter into a contemplative dialogue with myself. Hand-sewing is a healing method to release my pressure. After the repetitive work in a period of time carried out a sense of ritual, this process also gradually transformed clothes into a key role in the exhibition. Sewing old personal garments is like recovering injuries to connect their unknown history. Through a few spotlights only on artworks Circulation, Balance, Come In and Go Out, viewers would feel dim and memorial. Entering this space is like a spiritual effect to understand sewing as a healing process.

In early 19th century, the sewing machine was innovated and introduced by manufacturers to household, which even precedes washing machine and television. Sewing is not only established firmly as domestic labor but often regarded as an significant part of women’s life history. Therefore, sewing machines embody particular cultural meanings into women’s role in society. In retrospect, we can see the sewing machine has a great historical significance for Taiwan’s economic development and women’s life experience. Through the interviews with female users in different periods, the research discovers that the sewing techniques they grasped, the technology they selected and adopted, and maintenance skills they possessed all renegotiated relationship between genders in traditional tech products. This phenomenon not only fully shows women’s agency and the possibility of self-empowerment but also reverses the notion that humans are enslaved by objects. The research approach of this technology in use echoes modern technology historian, David Edgerton’s saying. When approaches of design realized the significance of female users, they can rebuild the connection with the society, and further bring those issues of marginalization to the surface through the discussion with different theories. Although the development of sewing technology changed the original form of skill, it wouldn’t take place of the skill which has internalized users’ body. From the point of women’s practice of the sewing machine, it is the key that transcends the long-existed gender myth in the technology field, redefines the real value of sewing labor, and realizes the possibility of self-empowerment.

The sewing machines industry in Taiwan is facing lots of problems and obstacles as the most traditional industries do. There are the problems such as micro profit in operation, the rising of production cost, the lack of innovative capability and so on. Therefore, it is necessary to explore how to enhance the added-value and brand revitalization of production in Taiwan’s sewing machines industry. The study tries to participate in the process of the brand revitalization, RICCAR in ZengHsing company by means of the steps of the establishments of the branch store, the brand revitalization, and the exploration of the innovative merchandise to form the conceptual framework among the practices. The study finds out that through the process of transformation of the sewing machines industry and brand revitalization, the first thing is to discovery the company resource, and then to develop the position and the personality of the brand according to its core capability. By doing these, it can make consumers feel and understand the consciousness of the brand and by enhancing the organization to create brand imagination strategy and value for maximizing profit in market competition. The executives in ZengHsing company hope that through the creative and innovative idea could reshape new brand story to further extend sewing culture and finally let ZengHsing company pursuit sustainable development from different version. Just because the elements of culture, innovation and industry are closely interconnected, the mutually multipliers can create the real new value.

There are many choices of domestic sewing machines on the market, inexpensive, simple function, and all kinds of mechanical sewing machines come in a variety of feature. But its only available along with the high-priced electronic computer sewing machines. Intensiveness of sewing machines market competition, consumers have their own budgets to be considered, when the consumer has locked the level that determine their reason to purchase it, the sewing machines in the market seems to be quite similar, the outlook and shape of the product will be determined the course of buying decision made by the consumers, with the similar price range, with almost the same functionality, naturally the consumers would prefer purchasing product that design according to consumer's preferences machine. In comparison with the previous metal sewing machines and the sewing machines on the market today, the shape of the home sewing machine was found to be significantly different, understand the evolution of the home sewing machine, will let us discover the points of changes and modification on the sewing machine had become. What changes in shape are in line with the emergence of new features, which improvement of the texture that will attract consumer's attention. And these had led the idea of sorting out the development of shape development of the domestic sewing machines. This study uses the literature exploration method and the case study method to conduct research on the shape evolution of domestic sewing machines. Through the Internet collected pictures of home sewing machines produced by Singer sewing machine from 1851 to 2016, after deselecting the unusable samples, gained 60 samples and process it into front view and top view diagram, establish a household sewing machine shape comparison table according to the chronological method, record it according to its year of produce, sample original image, material, control mode, front view and top view diagram etc. The household sewing machine was disassembled into three parts: shape, color and other parts for shape evolution analysis. The shaped part is subdivided into the nose, the cantilever, the pillar and the base. The shape evolution of these four parts is inseparable from the influence of the material and the control mode. The appearance of the plastic case in 1965 was the shape of a watershed in evolution. In a situation where the function is more complicated, the internal structure of domestic sewing machines is also becoming more and more complex, it's volume is increasing gradually, therefore the volume of the plastic case also rises linearly. The nose, the cantilever, and the pillar are thicker than the metal era, and the contour lines are also very different. The color evolution of domestic sewing machines can't escape the huge influence of materials, the metal sewing machine in the metal era is mostly black with gold decorative patterns, according to the different ages, it can be divided into gorgeous and simple type. There was no guide decorative pattern for the suture on the fuselage during this era. After entering the plastic case era, the background color is mostly white. The decorative colors of the mix are very diverse, and a different color plate sewing machine with different models having the same shape and function as the casing, with this circumstances allow the consumer to have more personal choices under the conditions. The other parts are divided into three power cords, the pattern table, and controller. The power cord is a must-have item that appears after entering the electricity era. In the metal era, the motor is mounted directly on the back of the sewing machine. The exposed position of the structure is almost always below the right side of the pillar. After entering the plastic case era, the motor is wrapped in the casing and is no longer exposed. The position of the power cord is also below the right side of the pillar. And the power cord can be removed for convenient storage when not in use. The pattern is only available in the plastic case era. The controllers for domestic sewing machines can be divided into five types. They are hand wheels, dials, knobs, and buttons on the screen. The hand wheel is the earliest controller. However, there was a significant difference in the shape of the plastic case during the metal era. The dial is also a controller that appears in the metal age. Its shape continues to the plastic case era after the change of the matching material. And it is still being used until today. The knob is a controller that appears only in the plastic case era. And it is the most commonly used controller in domestic sewing machines for plastic cases. It can be seen on domestic sewing machines in three different control modes. The button also appeared in the plastic case era. In addition to simply launching a single-function button, most of them come with lights and screens. The screen is electronically and the computer is equipped with the home sewing machine, more with buttons or knobs, there are also cases where you have touch function without having to match buttons. The size of the screen is related to what it displays. After analyzing the evolution of the various components, the research results obtained are as follows The appearance of new materials has significantly affected the shape change of domestic sewing machines. However, it is still affected to a certain extent by the appearance of the metal era. 2. The controller is an indispensable key to the formation of a household sewing machine. Through the arrangement of different controllers, it can make the sewing machine more likely and versatile in the shape of the household sewing machine.

A fundamental change in the global and textile industries took place on 1 January 2005, when the global quantitative quotas were abolished. International retail buyers are now able to reduce the number of their international suppliers, and can act on a preference to buy from suppliers anywhere in the world, offering the cheapest price on international orders. South Africa had been experiencing growth in cheaper imports, mostly at the lower end of the market, since 1994 when the political arena in South Africa changed, resulting in a reduction of its tariffs faster than the World Trade Organisation required. The post-2005 environment has seen a rapid increase in imports into South Africa, predominantly from Asia. This has resulted in numerous South African firms in the clothing and textile industries having to reduce their labour, outsource part of their production, or close down altogether, due to their inability to compete with their Asian counterparts. One area of the clothing and textile industries in South Africa that has the potential to assist in the sustainability of these industries is the development and growth of South African design content. Relatively new to South Africa is the growth in and recognition of South African fashion designers entering the market, which has resulted in the heightened visibility and activity of numerous inter-related industries, all servicing South African fashion, such as: model agencies, hair-stylists, make-up artists, the fashion media, fashion events and private boutiques. This study explores the experiences of and problems faced by South African designers in producing garments, meeting the price demanded by consumers, and being competitive in the current context of the local market that is dominated by the major retail chains. However, as this research paper will show, numerous South African designers are managing in different ways to succeed and in so doing, have created viable and successful design operations in a very competitive industry. The participants interviewed for this study are all independent designers and successful in their own right. Some have been in the industry for many years, while others are establishing their names and brands in the marketplace. All these designers manufacture from their own atelier (studio) or factory, thereby retaining production control. As and when the need arises, some outsource part of their production to CMTs (cutmake- and-trim specialists) or home-based workers. Many of the designers sell within both the formal and informal economy, some sell their products through their own boutiques while others sell through private boutiques. A common theme of these designers' success is that they grew their business gradually, learning incrementally about the business of fashion and how to maintain control over their cash-flows while slowly growing their visibility in the market. In the interviews, the designers reflected on the importance of customer relations, the importance of Fashion Weeks for promoting their products, as well as the importance of finding reliable suppliers. A common difficulty experienced by the designers is that of finding the correct balance between creativity and commercial success. The study concludes with some recommendations for the promotion and sustainability of South African design content, such as development of co-operative ventures or small clusters of designers working together and creating economies of scale in order to wield greater influence in the value chain. Another important recommendation made is that of designers finding suitable business partners, so that while the designers focus on creative work, their partner drives the commercial and marketing arm of the operation.Thesis (M.Dev.Studies)-University of KwaZulu-Natal, Durban, 2006

Abstract While thread, to most people’s knowledge, is vital to the textile industry, a fully automatic high-speed sewing thread winder is also a necessary machine in producing all kinds of sewing threads or embroidery yarns. Most of the recent sewing thread winders are automatic circulation systems that are mainly composed of air compressors. When using them, operators need to set up air-supply systems which easily generate energy waste. In addition, the noise made by air compressors is also harmful to human health. This thesis proposes a multi-cam mechanism driven by gear motor of small-capacitance type to replace air-pressure devices for the improvement of the automatic circulation. The motor rating required for each bobbin decrease from 370w to 180w, with machine weight reduced from 1000kg/4sp to 500kg/5sp, and thereby shortening product exchange time from 12 to 8 seconds. This thus results in a cost reduction of 50% and an increase in the competitiveness of the market. Keywords: textile machine, fabric machine, sewing thread winder.

The commonalities of emotions can bring people closer, furthering the interpersonal relationship. In addition to Art, as a way of personal expression, we regard art as a device which contains the human nature and one’s inner world, including the insight meditation and the dialogue with oneself. We extract both the physical and mental perceptions to develop the art which is an equipment filled with our life progresses. Generally speaking, artists are usually sensitive to the details of lives. A normal object, a simple sentence or even a beam of sunlight can arouse the pulses in the deep mind, bringing people immersed into the past memories. Looking back again, nevertheless, not only is the physiology entirely different, but the psychology, through the time elapsing. As well as the perceptions towards the past events have changed. All in all, no matter the facts happened before or the imaginative virtual when we review back , is significantly important foundations of how we exist now. We exist, we think and we grow. The progress of the growth is the life marking. And the home is the main place where we create markings. When existing in this world, an individual has started to receive various symbols, gradually buried and hidden in the one’s subconsciousness. Referring to these elements , we seem to be able to generalize an explanation to correspond with the diversification nowadays. In terms of Home, the link is deep rooted in the consciousness, imperceptibly influencing how we act or think. It is a powerful relationship that no one will forget or ignore. I, as an artist, am always recall all the wonderful markings made in the home, of my gratitude. In the traditional Chinese culture, women have no liberty to talk or comment. To convey their emotions and thoughts, women sew on the silk, forming various remarkable patterns. These patterns, forming by threads, absorb the women’s hope and yearn in the future, expressing the women’s lives progresses. Through the repeated motions and the crisscross thread or yarn sewing on the silk, the embroidery becomes the crafts which is full of semantics and emotions. Furthermore,the Ming dynasty feminist literature, especially, the embroidery is a momentous medium to be a factor in poems, rebuild the boudoir spaces and represent the life experiences then. By the embroidery, the female combine themselves with the self awareness, bodies, lives and art. Their affection, desire, sadness or happiness were all poured onto the fabric unreservedly in the silence embroidery room. After accomplishing an embroidered piece, they fulfill a ritual which convey the memorable markings in the past.

Taiwan is now facing the strong global competitions in different industries. As a result, the product itself, service value, quality and cost control become core essences of how a corporation can compete against others. Value Engineering (VA/VE), the method and the technology of which systematically analyze the products and its service functions, provides highest performance and low costs. It uses expert groups and their creative thinkings to analyze those wanted and unwanted features and propose alternative solutions without changing the value and the quality of the product s and services. Its main purpose is to ensure the core quality of the products and the quality and functions of the services and to get rid of unnecessary waste. This study is taking the retrospective bibliographic method to analyze the current VE applications, developments and achievements and to provide detailed process of its practice and the key success factors for others to use them as a reference to apply VE introduction.

Noise diagnosis of a sewing machine was conducted in this study. The experiment was performed by partly covering the machine body by noise insulation blankets, taking parts out of the sewing machine, changing the operating speeds, adjusting the stroke of the needle, etc.. The results show that the correlation between the noise and the vibration of the machine body is low. Reducing the vibration levels does not decrease the node level simultaneously. Concluded from the experimental results, the noise is very possibly generated and accumulated by friction and collision between the parts inside the machine, as also indicated by the frequency spectrum of the noise. The suggested improvements are changing the clearance and fitness in the linkages and sliding pairs, and replacing the worm gearing of the oil supply pump. Installation of noise absorption or insulation materials inside the machine proved to have negligible effects on noise reduction because the compact design of the machine makes the enough coverage of the materials inside the machine infeasible.
