The purpose of this study is to contribute in developing guidebooks that can be used in the courses of needlework study by comparing and analyzing the contents and organizations of needlework-related teaching resources available at the present university and fashion-related educational institutions. This research could help us train technical human resources to be highly adaptable in industrial settings. The results of this study showed that the overall organization of contents is mostly divided into such categories as needlework kits, basic hand sewing, seam finishing, partial needlework and decorative needlework. The study results also indicated that such content organization must be considered in basic needlework/sewing processes and that each content needs to provide more various and detailed information by reflecting recent trends in design. Partial needlework has different applications in terms of interlining attachment, subsidiary materials, or sewing techniques; therefore, consistent descriptions and standard guidelines should be given according to what material is used and which design is planned. This study found that most teaching resources covered only needlework or sewing techniques without giving specific descriptions of types of materials, lining and interlining that can have great influence on sewing methods and instructions on how to use the materials. These findings suggest that the teaching resources need to add further technical instructions for the proper use of materials especially in response to the recent release of brand-new materials and sewing machines in the market.

Handbags are a part of fashion and while their significance and value are increasing, research on this topic is lacking. This study defines handbags and categorizes the materials used for making handbags, sewing methods, expression techniques, and terminologies related to accessories. A total of 1,743 handbags that were released from the Spring 2020 to Fall 2023, Ready-to-Wear collections by 8 selected brands (Hermes, Dior, Fendi, Chanel, Louis Vuitton, Prada, Gucci, and Alexander McQueen), were analyzed. Out of these, 732 unique designs, excluding those with only color variations, were studied. The most common sewing methods were 'Cut, sewing, and edge painting', 'Cylinder arm sewing', 'Cut, edge painting, and sewing', and 'Inverted seam', in that order. Slim strap designs primarily used the 'Cut, sewing, and edge painting' method, whereas the body, especially with narrow and hard leather, was best suited for the 'Cylinder arm sewing machine'. For expression techniques, the most frequently used methods were 'Quilting', 'Metal Eyelet', 'Embossing', 'Printing', 'Punching', and 'Weaving', respectively. The characteristics of each brand's production methods, expression techniques, and accessories were as follows: First, the exposure of logos and monograms is prominent. Unlike clothing, handbags often prominently feature the brand's logo or monogram. Second, signature quilting is a prominent feature. Quilting effectively conveys the brand's signature style, providing cushioning, volume, and pattern effects. Third, sustainable development is a growing trend. Brands are increasingly applying eco-friendly and socially responsible designs.

This study aims at the improvement of sewing function through understandings of dynamic property about the sewing methods and the thread material selection in knitwear. The tensile strength and shear of KES-FB and the Instron were measured for the analysis of the mechanical properties. The knit cloth was structured In the plain stitch, $1\times1$ rib stitch and $2\times1$ rib stitch with the combination of wool and cotton. With regard to the sewing method, intralooping and interlacing were applied. For thread materials, polyester, cotton, wool and silk were used. Since silk has the lowest extension and similar values regardless of its construction in intralooping, it is available knit apparel with uniform elastic recoverv. It also has small shearing resistance. It can be used in apparel which needs big mobility, but it causes rutting problem. Therefore, it is suitable to use intralooping. When the same sewing yarn and textile are use, it can lower shearing resistance and extension in intralooping, Since wool needs a lot of extension energy and it can be cut, intralooping is more suitable than interlacing in sewing of wool. In interlacing using polyester, extension and shearing resistance are high. Therefore, it is suitable for knit sewing with high massing. Silk is not suitable for interlacing since it can be rut. Even though knit materials are different, the RT values of polyester and cotton are similar in same construction. Therefore, they can be substituted each other considering resilience after sewing.

The purpose of this study is to survey and analyze the conditions and automation of sewing machines and thereby, address the problems and their solutions to help local sewn products enhance their international competitiveness. The results of study can be summarized as follows : 1. It was found that most of the sample companies were getting smaller scale or pettier in terms of capital, number of employees or scale of factory. The interest in facility investment was relatively higher, which suggests high interest of our sewing companies in facility investment. 2. Most of the sample companies were well equipped with the essential and several auxiliary sewing machines, but poorly equipped with the special or automated sewing machines. 3. The ratio of idle machines was highest in sewing work, compared with cutting or finishing work, primarily due to decreased orders, aging machines or reduced manpower.

This paper describes a design of an induction motor control system for industrial sewing machines. On the basis of vector control principle, the control system is simulated by using the ACSL, implemented on a DSP(TMS320C31).A space vector modulation is used as the inverter switching strategy. For the application of industrial sewing machines, A fast acceleration (deceleration) and removal of velocity ripples are required, because a sewing quality and sewing machines life time depends on these characteristics. The designed control system has fast dynamic characteristics and small speed vibration. The result is applied to the industrial sewing machine and result are shown.

This experiment was designed to analyze the factors, which are very common in practical sewing, affecting on sewing shrinkage by using orthogonal array ($L_{27}$) table. The results were analyzed by using the computer program, PDP 11/10. The results showed that sewing shrinkage was increased up to 3 times of laundrying but no further changes could be found. Sewing shrinkage was affected much by the number of stitching and yarn tension and the rate increased with proportion to the number of stitching in unit length and yarn tension. When cotton yarn was used in P/C fabrics, the shrinkage was much smaller, but this results did not agree with other articles reported. Sewing by using $\sharp$11 needle and 1000$\~$1500r.p.m. seemed to lower the shrinkage rate.
