Mermelstein, Sylvia P. "Aspects of the design of a circular warp knitting machine." Thesis, Loughborough University, 2002. https://dspace.lboro.ac.uk/2134/34199.
Full textAbstract:
The warp knitting machine market has long been dominated by large-scale flat models, which have been steadily developed. Tubular fabrics are generally made in a special version of flat warp knitting machines containing two needle bars, one for each side of the tube, joined on the sides by yarns knitting alternatively on each bar. Warp knitting technology has failed to enter the circular knitting industry, dominated by weft knitting, due to its complexity in achieving warp knit structures in circular form. This thesis presents the design, synthesis, manufacture and test of an innovative method of producing tubular warp knitting fabrics, using a circular format rather than flat needle bars. This novel concept opens up many industrial applications from medical textiles to fruit packaging.

During the last decade medical applications of textile sensors have been growing rapidly and textile sensors are the focal research point for many sensor projects. Textile sensors are still not available as a mainstream product to replace conventional electric sensors and electrodes. Textile sensors can be integrated in a textile garment to measure vital signs of a human being. In this regard stretch sensors are able to measure breathing rate of a person. In this project we use seamless knitting technique to make stretch sensors using conductive fibers. The resistance difference between stretching and relaxing of these sensors gives a pattern for human breathing. Four knitting structures with different conductive fibers are made and tested with cyclic tester to construct a graph between resistance and time to find the knitting structure which gives the best results. Tests are also done to check the results after washing. These sensors can be used in breathing monitoring of patients during daily life.Program: Master Programme in Textile Technology

Full textAbstract:
Disrupting patterns places itself in the textile design field, more precisely in knitting. The aim is to explore cable knitting in combination with fair isle and intarsia designs with the motivation to disrupt the cable structure. The purpose is to give a bold, powerful expression to the cable, compared to the calm, classic look of the Aran sweaters, and in that way give a new perspective on tradition. The project is made by hand on a hand knitting machine for a knitwear design context. The intention is to bring back the value of the textile by focusing on the craftmanship. It is also made as a comment on fast fashion by disrupting the methods of working in the industry. The result is a knit design collection which displays three methods of working with cables. Traditional cable technique, moving stitches and giant cables. These methods are combined with intarsia and fair isle patterns. The methods can be applied in a knitwear design context, for example on a knitted garment. The focus of Disrupting patterns lies in the craft of knitting and is a comment on industrial fabrication and fast fashion implication on sustainable design. While the sustainable aspect is important, the main result of this project lies in the craft of knitting and to show a new method of working with cables and colour pattern techniques.

Full textAbstract:
This project places itself in the field of textile design within flat knitting textiles intended as prototypes for interactive textiles with multifunctional purposes and aesthetics. The purpose of the project is to suggest alternative design solutions towards knitted textiles in the field of sportswear that not only acts as a second skin both in terms of appearance and functionality, as well as aesthetic details once the knit interacts with a moving body. The aim of the project, but also offers visual and contrasting functions such as expandability, rigidness and stretch, as well as creating aesthetic details caused by movement of the human body. The design process was conducted in experimental knitting on both industrial and domestic knitting machines, workshops entailing the relation between the knits and the body as well as technically developing the proper bindings to work in unity. Analysis of the knits were made which led to the solely use of these bindings: rib, spacer, links links, ripple and mesh. The outcome of the projects resulted in four knitted textile prototypes, where one of them is designed as a product in the shape of a top, and the others as knitted fabrics each representing two opposing functions. The conclusion drawn in retrospect of this project that by placing opposing bindings parallel, such ripple and links links, it is possible to achieve two opposing functions as well as different visual perception within the same area of a knitted piece.

Full textAbstract:
Contemporary knitting over the past decade has experienced a recent resurgence in cultural interest and technical exploration. This research project aims to identify, through personal practice, the implications of knitting as undefined, removed from the boundaries of product. It is the dissolving of the lines between design, art and craft and exploring the domestically machine knitted textile via the use of materials and the inherent qualities of the fabric which are the driving factors of this research. It is through this exploration that my personal and creative process is diversified. The traditional connotations of knitting are historical, social and cultural, in particular hand knitting. Childhood memories of mothers and grandmothers knitting out of necessity, for clothing, often evoke feelings of safety, warmth and comfort. This familiarity of the looped stitches and understanding of the knit as garment binds knitting to fashion. Industrial knitting process, as scale of stitch is reduced, begins to remove this familiarity and creates an anonymity of structure and process, for example jersey knits used for t-shirts. This instant recognition for knitting as clothing is part of the design process where-by knitted fabrics work in unison with product. It is this boundary that has defined my professional practice designing for knitwear. This research involves a more experimental and fluid approach to producing the textile, considering the qualities and potential of the structure as something to celebrate in its own form. Designers such as Issey Miyake, Hussein Chalayan and the artist Rosmarie Trockel have been influential in taking fashion concepts into the gallery, often knitted. This movement of making conceptual and political statements, especially in the case of the industrially knitted pieces by Trockel, was a step to question the traditional and feminist perceptions of knitting and using the process as a material to create art. While these exhibitions explored the knitted textile in the form of fashion garment, the importance of diversifying the knitted cloth and displaying conceptual pieces is a major influence on this research. Also the more recent exhibition 'Radical Lace and Subversive Knitting', (Museum of Arts & Design New York 2007), has allowed for a reinvigorated forum for constructed textiles to be viewed as object, new product or purely as spatial explorations of structure. The impact of these ideas has allowed for the consideration of the textile being stripped back further and to remove the instant connot ation of product application. Exploration of materials, knitted structures and the manipulation of fabric without the constraints of identified product is the impetus of this project. The evolution of the outcomes is instrumental to the reactions of fibres, stitch and interplays of positive and negative space, while suggestions of product are accidental and created by the knitted form as it is removed from the machine. A personal interest in exploiting the knitted structures potential to possess transparency and opacity, become sculptural and changeable by hand have influenced the choices of material and stitch combination. This experimentation has informed my personal practice and the involved process of making.

Full textAbstract:
High-speed electromagnetic moving-iron actuators are experimentally investigated and numerically simulated, using digitally-controlled instrumentation techniques, lumped-parameter( magnetic equivalent circuit)networks,and field (finite-element) models. Various actuator topologies, based on the moving-iron principle, that are capable of achieving very high operating speeds, are also investigated. An optically-based and digitally-controlled instrumentation technique is developed to assessth e actuatord ynamic performance.A dual voltage (microprocessor-controlled) strategy is also developed to improve actuator speed of response. A lumpedparameter model that accurately simulates, with minimum computation, the dynamic behaviour of the actuator is developed and experimentally verified. This model, whose magnetic parameters are derived from static field results, accounts for magnetic saturation, 3D effects due to width change between iron parts and transverse edge fluxes, and the dynamic coupling of the actuator system variables. A static lumped-parameterm odel is developed,i n parallel, to achieve insight into the underlying actuator design principle, and rapid predictions of the effects of parametric changes. Two-dimensional field models are developed, using a commercial finite-element package, to accurately predict the saturation levels, and to estimate the mmf/flux characteristics of each actuator component (iron and air part) and force characteristics for use in the dynamic lumped-parameter model. The 3D effects are taken into account by incorporating the results of 2D scalar potential models, in typical transverse planes, into the longitudinal (main path) solution using suitable compensation factors. Transient eddy current effects are also investigated. The study is extended by surveying various topologies of moving-iron devices, and analysing their relative performances. The objective of this investigation is to establish, quantify, and compare the factors limiting the performance, particularly the maximum accelerationr ate.

In the paper, the control system of a computerized flat knitting machine is designed and implemented largely. A permanent magnet synchronous motor is used to operate the machine. We design the motor drive that discrete power MOSFETs are adapted in the inverter to reduce the cost. In order to get zero steady-state error, the PI control is considered in the velocity control loop. Microcontroller, 8052, programs the drives of seven step motors to manipulate the controls of cam, left stitch, and right stitch of front-end and back-end, and racking. The color and style of the accessories of clothing is programmed by using a keyboard, PC, or an external memory card. There are three communication protocols, RS232, RS422, and RS485, used in the system to transfer the instructions and data. Chapter 4 is used to apply the technology of the product development process to expect finishing the duty in each task and then accomplishing the product design and implementation in considerable time. Gantt chart used in this chapter is a project planning tool that can be used to represent the timing of tasks required to complete a project. Hope these kinds of research can be finished in shorter time to reduce the time wasting. Because of the technological change with each passing day, innovative machines are designed and implemented in a very short time. That’s the reason why value engineering will be applied as part of my gradation thesis. Value Engineering is an effective methodology for reducing costs, increasing productivity, fostering innovation, eliminating unnecessary design element, ensuring cost-effective project, and improving quality with required performance, reliability, quality and safety in a product, facility, design, system, service or process. Deeply hope this could supply a new thought to innovate new products.

Woman with their beauty, has always been one of the biggest muse to fashion designers, they are given thousands of choice to beautify themselves. In this collection, I want to contribute my designs to the independent women of our time, give them another option while dressing up. An independent woman in this modern busy world somehow reminds me of a lone wolf - alone but not lonely, strong, elegant, fearless and beautiful. That is why I use the image of the woman and the wolf for my graduating project. During my two year researching and learning in Shute University, I have spent my time learning and practicing machine weft knitting, photo transferring and hand embroidering techniques. With the experience I have on these techniques, I feel that when being used together, they could create interesting and beautiful clothing. Results shows that photo transferring technique is not suitable to use on knitted fabric, manual knitting machine can only function properly with yarn which its diameter is smaller than 0.5mm, and knitted fabric length while still on the machine is 30% longer than after we take it out of the machine. From the results, I chose to use machine weft knitting and hand embroidery technique to create a collection for women between 25-35 years of age. Focus on designing dresses with simple yet interesting and elegant silhouette, showcasing the feminine and sexy part of a woman without being overly revealed. With the fascination I have for this topic, using strong yet fragile characteristics of the women to design the structure of the dresses, and the image of wolves and their habitat to create the fabric and decorations, I finally completed my collection named “Duologue” with a total of 8 costumes.

This research integrated the design of rolling and folding functions of a circular knitting machine, using a single power input for the entire mechanism with the clutch as its key component. The clutch played an important role. When it is not engaged, rolling function is used, while the folding function is activated when engaged. The integration of rolling and folding functions raises the value of the machine. This research followed previous works to study knitting machine. Previous analysis and classification were referred to create better mechanism type. A 3D model was built for detailed design and simulation to determine feasible dimensions. Finally, a new rolling and folding mechanism was designed, built, and filed for patent application

This research aims to integrate the design of Central Yard Feed Mechanisms with Flat Knitting Machine, which uses a power input mechanism, where the clutch plays an important role. The machine weaves by using the clutch to control how yarn enters the machine and by working with yarn guide bars and yarn guides. Compared with the previous designs, the central yard feeding mechanisms for flat knitting machine is devised to increase the competitive advantage in the market through the same weaving action and simpler structure of the machine. In this research, two ideas, both controlled by the clutch, are designed based on different methods of controlling how yarn goes into the machine. The first method uses pawls and ratchets as the major structure of the clutch, and the second method uses the yarn guides and the clutch to control the contact between the block and the clutch. A wide range of patents and references were collected and analyzed to find out the strengths and weaknesses of each design. The function of the current size central yard feed mechanisms for flat knitting machine is improved trough two new and innovative methods. The above two methods were verified through motion simulation and the interference check by CAD software.
