In order to investigate the influence of thread tension on the structure of lockstitch seam, stitch tightness and seam balance ratio are measured at various tensions of needle thread and bobbin thread. The structure of lockstitch was shown in terms of skeleton stitch models to obtain quantitative analysis of stitch tightness. The balanced seam formed to the rectangu1ar stitch model under low bobbin thread tension, but the fabric tightness produced by interlaced needle and bobbin thread under high bobbin thread tension. In this paper, new equation to obtain seam balance ratio was proposed for a lockstitch seam. By using the new equation, the seam balance ratio was not affected by the stitch density and fabric thickness. In order to form the balanced seam, the ratio on tension of needle thread and bobbin thread was about 6:1~7:1 in this experiment.

In the automobile industry, structural health monitoring of fiber reinforced polymer composite parts is a widespread need for maintenance before breakdown of the functional elements or a complete vehicle. High performance sensors are generally used in many of the structural health monitoring operations. Within this study, a carbon fiber sewing thread has been used as a low cost laminate failure sensing element. The experimentation plan was set up according to the electrical conductance and flexibility of carbon fiber threads, advantages of preforming operations, and sewing mechanisms. The influence of the single thread damages by changing the electrical resistance and monitoring the impact location by using carbon thread sensors has been performed. Innovative utilization of relatively cost-effective carbon threads for monitoring the delamination of metallic inserts from the basic composite laminate structure is a highlighting feature of this study.

This study investigated mechanical properties, drape coefficients and node indices of stretch fabrics. We applied mechanical properties to exhibited tailorability control in HESC and evaluated making-up. The mechanical properties such as tensile, bending, shearing, compression, surface characteristic values, thickness and weight were measured by the KES-F system and drape coefficient by drape tester. The summarized results of this study were as follows; First, stretch fabrics, almost, shown high stretch in weft inserted polyurethane yarn fabric and had a ${\pm}2{\sigma}$(sigma) range of shearing, compression, surface and thickness, except bending and weight, as compared with Japanese women's thin dress fabrics. Second, bending had a positive correlation in stiffness, anti-drape and flexibility & softness. Shearing had a negative correlation in crispness and scroop. Surface properties had a high contribution in fullness & softness. Third, The drape coefficient was found by measuring the mechanical properties according to the obtained regression equation. Forth, many problems are expected in overfeed and cutting operations in sewing process. In the decision of the good external appearance using TVA, only 26 of 55 samples are included in the range of the good external appearance. Fifth, in the regard of the result for sewing control, warp values are not necessary to control in the all kind of items. But weft value in the RT and EM are out of non-control zone. So we need a special management during sewing process.

The Imwon Sipyukji of this study was compiled by Seo Yugu (1764~1845), a famous agronomical scholar of the late eighteenth century. The contents of this book are divided into sixteen chapters related to all the important parts of rural home life ranging from daily routines to social life covering the agro-industry and the six skills of manners, music, archery, calligraphy, mathematics and horseback riding. Seomyongji, one of the sixteen chapters, covers all that is necessary for living a rural existence such as house-building, clothing adornments and transportation as well as how to make and use daily household items. The contents of the Boksik Jigu sub-section in the Sumyongji chapter consist of eight large units covering men's and women's clothing, bedding and pillows, sewing tools, belt and shoes accompanying the attire and storage for clothes. These eight are further subdivided into 65 items, each warranting a detailed explanation. My study will translate the original Chinese text of Boksik Jigu into Korean. This sub-section in the Seomyongji chapter will facilitate an investigation into the information contained therein on attire and accessories.

I The Purpose of this study is to look in to the production of high-functional clothing industry, such as item, style, layout, labor, suggest some effective solutions and alternatives for them. 23124554 For this purpose, the companies specialized in manufacturing of special high-functional clothings were sampled for a survey using interview and a questionnaire. The results of this study can be summarized as follows; It was found that since demands for high-functional apparels are low and their sewing processes are much complicated requiring expensive equipments, only a few companies are engaged in such apparels. In addition, since the quantity of order s small and material inputs are more frequently changed, the sewing processes on the production line need to be changed together with the production layouts. On the other hand, as the materials used are very special, expensive equipments should be used, for which the companies feel much burdensome financially. Accordingly, t is deemed necessary for the high-functional apparel manufactures to specialize the processes requiring specialized equipments or outsource some of them or recruit highly-skilled workers.

This study aims to verify the sewing technology and the expression of the virtual garment program by comparing the appearance similarity between the real and the virtual power shoulder jacket. To this end, the H and the X silhouettes of the power shoulder jacket were selected as the reference designs. After making the reference designs into real jackets by applying the human body dimensions of women in their twenties, virtual avatars and jackets were produced using CLO 3D programs. The results showed that the H-type with only expanded shoulders and less design variation had a high similarity between the reference photo and real garment, the real and virtual garment, and the reference photo and virtual garment. The power shoulder jacket of the reference picture was well reproduced in the real and virtual garments. Conversely, the X-type jacket, which is a tight fit and has many design variations, showed somewhat low similarity in the circumference items and the basic construction line. Especially in tight-fitted power shoulder jackets, the fact that shoulder angles and the essential items for pattern making cannot be reflected in reproducing virtual models was found to be a limitation in increasing the similarity of virtual clothing. Furthermore, the sewing system gap between the real and the virtual clothing exposed a difference in the appearance of virtual clothing.
