Abstract:

A measuring system has been developed to capture and analyze forces directly encountered by the needle bar and presser bar from a high speed sewing machine. The forces recorded from the needle bar reflect those encountered by needle penetration and withdrawal. The forces recorded from the presser bar are those transferred by the feed dog as it advances the fabric each sewing cycle. A measuring system known as the ncsu sewing dynamometer is capable of detecting changing sewing parameters, including variations in the material being sewn, increasing plies of fabric, frictional forces on the sewing needle, and the dynamics of the feeding system.

Abstract:

Prevalence of neck-shoulder pain among sewing machine operators is well known. It may be due to the nature and incorrect posture used by sewing machine operators while performing sewing work. However, up till now there is no empirical evidence that can be used to relate the risk factors that would results towards the development of neck and shoulder pain among sewing machine operators. The main objective of this study is to identify and investigate the risk factors that result in neck and shoulder pain among Malaysian sewing machine operators. Twenty female sewing machine operators took part in answering a survey questionnaire to investigate the prevalence of neck and shoulder pain among sewing machine operators. The survey questionnaire was divided into five sections: socio-demographic, work background, workload information, physical exposures and physical musculoskeletal symptoms experienced by workers. Having done that, sewing machine operators who have been screened with neck and/or shoulder pain was evaluated with Rapid Upper Limb Assessment (RULA) to determine the level of workplace risk factors. Subjects without neck and/or shoulder pain were excluded. Results of the study shows that all sewing operators were expose to risk of prolonged sitting, repetitive task and working at high speed. Ninety five percent of sewing machine operators had experienced neck and/or shoulder pain and 80% of them were exposed to high work risk factors that require them to undergo further investigation. Shoulder pain was found to be strongly correlated with high work risk factor among sewing machine operators (p<0.05). In conclusion, occurrence of shoulder pain among sewing operators is due to posture and nature of sewing work.

Abstract:

The textile sector has become an indispensable part of the Turkish economy. The sewing machine is a long-lasting and easy-to-use tool widely used in the garment industry, which is a branch of the textile industry. The sewing machine is an indispensable production tool for the textile industry and sewing machine selection is a significant decision for the production performance of textile companies. Selecting an appropriate sewing machine increases production performance, while selecting an improper one reduces production performance. The sewing machine selection problem is a typical machine selection issue. Many criteria, such as cost, productivity, safety etc. are considered in the machine selection. Therefore, MCDM methods are applicable to solve the machine selection problem. This study develops an integrated grey MCDM model including Grey AHP and ROV-G to select the most appropriate sewing machine for an apparel textile company.

Abstract:

This study examines the Singer Sewing Machine Company’s strategies for selling family sewing machines on a global scale. In marketing the sewing machine, the American-headquartered Singer focused on ornamental embroidery or “fancy” sewing, defining home sewing as art, to distance the company and the appliance from negative perceptions of women’s garment work as industrial manufacturing. Singer created its Embroidery Department in the early 1890s in response to consumers’ sewing preferences. The department reflects how the home became a site where global capitalism was constructed and articulated. Singer’s Embroidery Department had representatives in many countries, coordinating expositions and other advertising. In the case of Singer in Spain and the United States, women who took part in the department’s work were an essential part of the corporate-integrated operation. This article examines the relationship between Singer’s corporate strategies and gender and culture in Spain and the United States.

Abstract:

Purpose The apparel industry is a labor-intensive industry, which depends mainly on the performance of the worker. The purpose of this study is to present an ergonomic redesign of the sewing machine workstation, with different sewing table heights and inclination angles, based on the operator’s anthropometric data. Design/methodology/approach A flexible ergonomic sewing table has been designed, four main workstation-setting factors were studied; sewing desk inclination angles – X_1, height – X_2, sewing machine type – X_3 and operator’s body mass index (BMI) – X_4, with three levels for each factor, except sewing machine type, which only has two levels. The study was undertaken to specify the limitations and advantages of each combination tested. Different measurement techniques were used; subjective information, production rates – P, working postures (head, neck and trunk inclination angles in the kinematic stage) were measured. Findings Sewing operators’ sitting posture angles in the kinematic stage were affected more or less by their anthropometric measurements and the type of sewing machine. These two factors should be taken into consideration when ergonomically redesigning the sewing machine workstation. Practical implications A new ergonomically redesigned sewing machine table can be incorporated into garment factories, taking into consideration the BMI of the operators to improve their productivity and reduce musculoskeletal disorder complaints due to incorrect operators’ posture. Originality/value An important correlation was found between the sewing operator’s anthropometric body measurement – BMI and the type of sewing machine (with significant R^2 = 0.8385 and 0.9764 with both the head and neck inclination angles O_H, O_N, respectively).

Abstract:

AbstractSewing machines, one of the first mechanical consumer goods to be mass produced and sold worldwide, provide an important case study for the understanding of global history in terms of the global diffusion of goods. However, as the case of colonial India demonstrates, it is what happens to such goods on their arrival in the recipient society – their emergent social history and growing indigeneity – that then demands analytical consideration. By tracing the changing nature of India’s sewing culture and sewing-machine use, linking it to occupational shifts, racial identities, and gender roles, to changing marketing techniques and advertising strategies, this article shows how closely the relative success of the sewing machine was bound up with local artisanal practices, commercial agency, and the transformative forces present in Indian society. It further indicates how Indian production of sewing machines by the 1950s built on several decades of acculturation and local experience of their sale and use.

Abstract:

We present a fluid-instability-based approach for digitally fabricating geometrically complex uniformly sized structures in molten glass. Formed by mathematically defined and physically characterized instability patterns, such structures are produced via the additive manufacturing of optically transparent glass, and result from the coiling of an extruded glass thread. We propose a minimal geometrical model—and a methodology—to reliably control the morphology of patterns, so that these building blocks can be assembled into larger structures with tailored functionally and optically tunable properties.

Abstract:

Introduction: Sewing machines a set of mechanisms that work together, of which the most dynamic mechanism is the one that drives the needle. Stitch quality, the stitch strength and the productivity of the sewing machine largely depend on the work of the needle bar mechanism. The main task during the study dynamics of the sewing machine mechanisms is to determine the energy balance. Purpose: The aim is to determine the total energy consumed by the mechanisms per one full rotation of the main shaft of each machine; the share of energy consumed by each unit of the needle bar mechanism for one turnover; the ratio of the energy of each of the links of the mechanism both during the working motion and during the free motion of the needle. Materials and Methods: The object of the study is the energies of the needle bar mechanisms of the sewing machines Juki DDL5550 and Textima 8332. An energy distribution analysis was performed during the working process and the free stroke of the sewing needle. The energies of the mechanisms of the two sewing machines were compared. Results: Were calculated maximum energy values are as follows: of the rocker: for Juki DDL5530 Ek = 2,8051 kg.m2/s2 and for Textima 8332 Ek = 1,3864 kg.m2/s2; of the executive links - the needle bars: for Juki DDL5530 Ek = 5,9507 kg.m2/s2 and for Textima 8332 Ek = 4,3696 kg.m2/s2; general energy of needle bar mechanism: for Juki DDL5530 Ek = 8,7487 kg.m2/s2 and for Textima 8332 Ek = 5,7416 kg.m2/s2. Conclusion: The comparative analysis reveals that the energy consumption of the needle bar mechanism of Juki DDL5530 is significantly higher. Consequently, the energy consumption indicator of the Textima 8332, which is directly driven without a clamp, is more efficient.

Abstract:

Purpose – The purpose of this paper is to present, an optimization problem based on the imperialistic competitive algorithm (ICA) approach for optimizing the needle velocity and variation of needle acceleration in a link drive mechanism of a sewing machine. The optimal geometry of the link drive has been achieved using a non-linear optimization procedure. Design/methodology/approach – As an important study in this case, the authors might refer to a previous work in which they introduced the possibility of replacing the slider-crank mechanism, that is typically used in sewing machines, with a link drive mechanism. The authors regenerate the optimization problem by modifying the objective function and follow a novel optimization method based on the ICA to overcome the drawbacks of that work. In addition, further modification of the objective function with respect to the variation of needle acceleration is applied to assure smooth movement of the needle during sewing process. Findings – The results showed a significant improvement with respect to the optimization of needle velocity and variation of needle acceleration in comparison to that previous work. This clearly justifies the efficiency and reliability of the optimization formulation based on the ICA approach. Originality/value – Needle temperature is considered as an effective parameter on sewing process efficiency and stitch quality. Needle heat generated during sewing process is directly related to needle velocity in penetration zone which in turn depends on the needle driver mechanism of sewing machine. According to literature survey, few researches have focussed to design a driver mechanism of the sewing machine to reduce the generated needle heat. This mechanism has the ability of reducing the penetration velocity of the needle without affecting sewing speed which consequently can reduce the needle heat generated during needle penetration. The work here is novel regarding implementation of optimization algorithm for this mechanism.

Abstract:

XYZ is a Small and Medium Enterprise (SME) that manufactures dolls from rasfur and velboa fabrics. XYZ uses a flowshop with a make-to-stock production system. The problem that occurs in XYZ is that they have not been able to achieve production targets so they cannot complete customer demands. This study aims to simulate the production system so that it can be analyzed problems and taking the best solution. The method used in this study is modeling and simulation using flexsim 6.0 software. After modeled on Flexsim, it can be seen that significant problems exist in the flow from cutting to the sewing machine and the sewing process time is too long. Therefore, the researcher tries to add a sewing machine as an investment so that there are no lost opportunities. After the addition, it turned out that XYZ was able to produce an average of 80 dolls per day by adding 2 sewing machines as a future investment.

Abstract:

Working processes in the technological sewing process are performed on machine systems characterized by machine-manual work, where the worker and the machine work simultaneously. Such a work system requires a great deal of responsibility in terms of quality, quantity, and the accurate and timely execution of tasks, which requires the quick and accurate response and extremely good psychomotor and visual skills of workers. This paper presents the process of determining the working method and normal times for the technological operation of runstitching women’s blouse collars, which includes the design of an ergonomically designed workplace, the selection and technical equipment of the universal sewing machine and the determination of the optimal work method and normal times using the Methods-Time Measurement (MTM) system. The research results obtained indicate that the technical equipment of a universal sewing machine has a significant impact on the structure of the technological sewing operation and the working method, i.e. the number of auxiliary manual technological suboperations. Improving technical equipment, i.e. increasing the number of automated functions used on a universal sewing machine, reduces the number of auxiliary manual suboperations, reduces the time required to perform the technological operation and increases work productivity.

Abstract:

The paper investigates the relation between seam pucker, woven fabric formability, and the presser foot displacement during stitch formation. Superimposed seams of class 1 were sewn in warp and weft direction using woven fabrics for tailored garments. The presser foot height was continuously monitored during stitch formation for different sewing machine speeds. The foot displacement during the sewing cycle was correlated with seam pucker. The obtained results showed various patterns of pressure foot displacement regarding the sewing machine speeds. It was found that at a lower machine speed there is no bouncing of the presser foot and the ratio of the height of the presser foot before and after rising and declining movement versus double thickness of the fabric (h/T1), correlates significantly with the seam pucker percentage. The fabrics having a higher h/T1 ratio showed a higher percentage of seam pucker. The obtained results suggest that online monitoring of this parameter can be a useful indication of on-seam pucker appearance, providing reliable means to obtain a quality seam.

Abstract:

The vibration of the operational sewing machine is caused mostly by the fundamental frequency of the motor and its harmonic frequencies. The experimental modal analysis was conducted on a certain industrial sewing machine to identify its modal parameters. The operational deformation analysis was carried out and the actual deformation in the first six harmonic frequencies of the main speed frequency was obtained. Finally, the dynamic characteristic was identified by analyzing how each mode influences the harmonic vibration. This paper provides a valuable reference for noise reduction of the sewing machine.

Abstract:

Sewing is one of the oldest textile arts which are still popular among the masses of India. Beyond being an art work, sewing serves as a source of livelihood for millions of people. In modern India the major part of the sewing industry is confined to the rural villages spread across the north and the north eastern states of India. Most of these villages are still to receive electricity and those of whom have, are sustaining on the verge of energy poverty. The operation of a sewing machine can be harnessed to produce electricity for small scale purposes. This can be used for charging batteries, mobile phones, lamps, emergency lights. The rotational aspect of the sewing machine wheel can be used to generate power. Power generation is facilitated by using an Alternator. The usage of an Alternator over a DC Motor or Dynamo has added advantages which are described in detail in due course. This paper is intended to present a method to generate power by effectively harnessing the rotational capability of a sewing machine wheel. The paper also deals with the advantages of using an alternator over other electricity generating devices.

Abstract:

This study aimed to establish an automatic sewing process for garment production according to textile properties. An automatic feeding system and a self-made template were introduced to an industrial sewing machine. Two types of stitches were performed on fabrics with various physical properties and surface roughness using this automatic sewing machine. The appearance, stitch length and width, seam strength, and seam efficiency were evaluated according to the sewing conditions, such as presser height and sewing speed. In addition, the correlation between textile properties, sewing conditions, and sewability was analyzed to derive a regression equation for sewability. The evaluation showed no difference in the lock stitch condition. On the other hand, under the zigzag stitch condition, the stitch width differed according to the presser height, which also affected the seam structure. The optimal presser height for each fabric was derived from the experimental results. In terms of the sewing speed, however, the seam strength was the best at 200 RPM in the lock stitch and 400 RPM in the zigzag stitch. The moderating effect of the presser height between textile properties and sewability in the lock stitch condition was confirmed. This result can be used as basic data for establishing an automatic sewing process for smart factories.

Abstract:

AbstractEveryday technologies of the nineteenth century—mass-produced items that were small, sturdy, and affordable—transformed the daily lives of working people in Asian colonies. There is already a large literature on colonial technology transfer and a specialist literature on the sewing-machine, which draws on Singer archives, production figures, sales techniques, and advertising to establish uptake by households from North America to the Philippines, India, China, and Egypt. Still, documentation of how and why imported objects such as the sewing-machine were appropriated is difficult to find because, unlike elites, ordinary people left few records of their own. Here a visual archive is investigated to complement existing studies. Photographs and early moving pictures from the former Dutch East Indies show that ordinary Indonesians sought and appropriated imported goods such as the sewing-machine. The colonial camera's visual record of sewing-machine operators displaces attention from the more impersonal trade and productivity statistics. It brings the silent user into the history of technological uptake and allows us to consider the repercussions across a wide social band and period. Indigenous tailors and seamstresses expanded their own work options. Through the Singer they fitted out and launched their compatriots into modern jobs and lifestyles in the Dutch colony. The sewing-machine changed habits, manners, and expectations; machine operators influenced senses of propriety, fashion, and status. Appropriation of mundane technology demonstrates that modernization was not only a process trickling down to the masses from Westernizing elites; it also bubbled up from below.

Abstract:

An automated sewing machine controller and a three-dimensional measurement system have been developed to find the optimum sewing condition that minimizes seam pucker. It is already known that there are various factors affecting the seam pucker. However, the selection of sewing conditions for reducing seam pucker has relied on the experience of skilled workers. In this study, thread tension, presser foot pressure, and stitch length were chosen as the parameters. Parameter settings were controlled by a computer, which enabled the automatic generation of samples with various combinations of sewing conditions. The seam pucker grade was determined from the scanned three-dimensional sample using a fractal dimension calculation. The optimum sewing conditions for a given sample can be determined from this result. The efficiency of the system was verified by comparing the newly developed method with the existing subjective evaluation method.

Abstract:

In the context of converging media technologies, the concept of mobile media embedded in wearable material was introduced. Wearable Computing, Fashionable Technology, and Smart Textile are being developed at the intersection of media, art, design, computer science, and engineering. However, in Germany, little research has been undertaken into Smart Textile in education1. Those activities are not realized at school in the context of artistic processes in general MINT2 education in classroom settings. In order to research the interplay of electronic textiles and wearable technology, hard and software tools, such as Arduino LilyPad, a programmable board designed for stitching into clothing and flexible applications are scrutinized. In the project, contemporary media art projects in the field of Fashionable Technology are explored to inspire interdisciplinary technology education. The project described in this paper engages girls in technology and engineering by integrating artistic processes as well as a more playcentric approach to technology and engineering education.
