This study surveys the variation of the physical properties such as denier, tensile property and thermal shrinkage between seven domestic and foreign PET filaments manufactured by China and Taiwan. For this purpose, the specimens prepared were PET POY 239d/96f made in china, and PET POY 255d/48f made in Korea as a coarse filament. As a fine filament, 120d PET POY made by Taiwan, China and 6 domestic companies were prepared. The various physical properties such as yarn denier, yarn mechanical property and wet and dry thermal shrinkages were measured according to the each layer divided by 50,000m of the cake, and between and within yarn physical properties were analysed and discussed with the domestic and foreign yarns. These results provide fundamental data to the SME related to the yarn finishing and weaving for developing high added-value and high sensitive fabrics.

Fall-arrest systems(maximum arrest force and allowable free-fall) have been widely applied to provide a safe stop during fall incidents for various industrial activities. Fabric structure affects on the mechanical properties of shock energy absorber. The object of this study is to perform the basic research for the evaluation of the capacity of fall arrest energy absorber in relation to the different interlace yarn density. In this work, pack style energy absorber was prepared by weaving 10 types(Interlace yarn density used high tenacity PET 1000D : 60, 59, 58, 57, 56, 55, 54, 53, 52, 51). The paper presents the results of theoretical investigations of the performance of adjustable absorber during fall arrest. Dynamic load tests based on the EU fall protection equipment standard(CE : EN355:2002) were conducted. Results showed that the maximum arrest force by dynamic load test of energy absorber was satisfied with global standard(below 6,000N). Also, Maximum allowable free-fall of energy absorber showed below 1.75m.

This paper proposes a robust tension control algorithm for the let-off and take-up system driven by servo motor which is robust to disturbance and tension variation by using SVR(Support Vector Regression). Quality of textile goods in fiber manufacturing process highly depends on control of let-off, take-up and tension which are essential for constant tension control of yarn and textile fabrics and correct length of them. The physical properties of textile fabrics are very sensitive to several factors(temperature, humidity, radius change of warp beam etc.) which result in tension change. Rapid development of fiber manufacture machine for higher productivity requires control system for let-off, take-up and tension for robustness to sharp tension-variation and quick response. The validity and the usefulness of the proposed algorithm are thoroughly verified through numerical simulation.

Water-based acrylic sizing agent(GSW-7000) was prepared by emulsion copolymerization for sizing polyester yarns. Ammonium salt version of the acrylic sizing agent offered greater abrasion resistance to weaving forces and water resistance for water jet loom. GSW-7000 exhibited proper viscosity for sizing, high penetration ability and excellent adhesion to polyester yarn. It was possible to reduce the size pick-up to 70~80% of ordinary solvent-based sizing agent due to excellent adhesive strength of GSW-7000.

$Premi\grave{e}re$ Vision is a leading textile collection held since 1973. In this study, textiles for 2004/05 F/W season in $Premi\grave{e}re$ Vision were analyzed at the various point of view, such as general trend, sub-theme, fiber content, color trend, structure, yarn trend, pattern, texture, decoration, finishing and other technical treatment, and functionality. There were three general trends; natural/ecology, geometry, and combination. Natural color and texture were widely used over the fabric exhibited, and irregularities expressed the natural trend of textiles. Geometric patterns were used for knit as well as for woven. Geometry expressed by various methods such as weaving, knitting, printing, shearing, embossing, and etc. However, geometry shown in this season was not a clear form expressed by weaving, but a blurry, irregular form expressed by various other methods such as knitting. The combination among heterogeneous fibers, yarns, colors, images, and textures was usual, however, the harmony among them was accomplished.

Currently smart textile market is rapidly expanding and the demand is increasing integration of an electronic fiber circuit. The garments are an attractive platform for wearable device. This is one of the integration techniques, which consists of is the selective introduction of conductive yarns into the fabric through knitting, weaving or embroidering. The aim of this work is to develop a golf bend driven prototype design for an attachable Arduino that can be used to assess elbow motion. The process begins with the development of a wearable device technique that uses conductive yarn and flex sensor for measurement of elbow bending movements. Also this paper describes and discusses resistance value of zigzag embroidery of the conductive yarns on the tensile properties of the fabrics. Furthermore, by forming a circuit using an Arduino and flex sensor the prototype was created with an assistance band for golf posture training. This study provides valuable information to those interested in the future directions of the smart fashion industry.

The purpose of this study is to review the literatures and the wall paintings of the ancient tombs of Koguryo in an effort to try to understand the characteristics of the culture of dyeing in Koguryo. The research findings follow: 1. The colors that were in vogue in Koguryo are five cardinal colors (red, blue, white, black, and yellow) and compound colors, like purple and green. Those colors were used in some or all parts of the clothing and even on some parts of the body. 2. Some clothing of Koguryo as shown in the wall paintings were made with a single and solid color by dip dyeing method. But the majority of the clothing had a variety of patterns. Among the patterns, the geometrical dot pattern took the majority. 3. The dyeing techniques used in Koguryo were printing, yarn dyeing, embroidery, wax resist dyeing, drawing and painting. The development of yarn dyeing method, weaving with silk-threads dyed in various colors, enabled to produce Geum fabrics, which were used for the upper classes' clothing. 4. The esthetic features represented in the colors of Koguryo include the beauty of contrast coloring, preference for red, preference for geometrical patterns, and the harmony of yin and yang.

Th)s study was carried out of the historical characters and textile coservations for Mrs. Danha Lee's Wonsam. As the textile material was silk, dry cleaning method was suggested. The solvents for dry cleaning were n-hexane, n-decane, and benzene. During the second cleaning process, the dry soap(HI-TECH, 120:1, volume ratio) was added to the mixed solvents. The reaction's temparature was $20^{\circ}C$, and the reaction's time was 30 minuutes. It seemed to be a gift for hot from the Royal Family because of the attachment of pheonlx hungbae. This wonsam was decorated symmetrically by gold weaving yarn, the basic fabric was green silk satin with glorius letters and floral patterns. It was made on the 17th C and the oldest thing among them.
