On April 28th of 2006, a set of Buddha's reliquary was excavated from the pagoda in n Nacsan Temple. According to the record, the relics were put in the pagoda in the 18th year of King SookJong in the Chosun Dynasty (1692). The present paper examines ten pieces of wrapping clothes covering reliquary found in the pagoda. They are especially precious data in the history of textiles because they were blocked off from outside and was preserved in good condition with vivid colors still remaining after more than 300 years. Of the ten pieces of wrapping cloth, five were double-layered and the other five were single-layered. They include 15 pieces of silk fabric but, excluding repeated use of the same silk fabric, the total of 11 pieces of silk fabric were examined. All 11 kinds of silk fabric were patterned, 9 of which were Satin and the other 2 were Twill. Of the 9 Satin pieces, 8 pieces were 5-end satin which had the ground of 5-end warp satin with the figure of 5-end weft satin. The remaining 1 Satin piece were more splendid with prominent figures by using warp and weft of different colors. The 2 Twill pieces used twill weave-the ground was 3-end warp twill and the figures were 5-end weft twill. Both of the Twill pieces were weaved with character patterns, partly using wrapped gold thread as supplementary weft. The patterns of 11 pieces of silk fabric include flower, dragon/phoenix, cloud, and geometric patterns. Five were flower patterns, three were dragon/phoenix patterns, two were geometric pattern, and one was cloud pattern. In addition, various treasure patterns, character patterns were utilized as supplementary patterns. The flower and phoenix patterns reflect characteristics of the textiles of the 17th century whereas check pattern and cloud pattern were very unique.

Current global textiles and fashion industries have gradually shifted focus to high value-added, high sensibility, and multi-functional products based on new human-friendliness and sustainable growth technologies. Textile design CAD systems have been developed in conjunction with computer hardware and software sector advances. This study compares the patterns or images of actual woven fabrics and virtual fabrics prepared with a textile design CAD system. In this study, several weave structures (such as fancy yarn weave and patterns) were prepared with a shuttle loom. The woven textile images were taken using a CCD camera. The same weave structure data and yarn data were fed into a textile design CAD system in order to simulate fabric images as similarly as possible. Similarity Index analysis methods allowed for an analysis of the index between the actual fabric specimen and the simulated image of the corresponding fabric. The results showed that repeated small pattern weaves provide superior similarity index values than those of a fancy yarn weave that indicate some irregularities due to fancy yarn attributes. A Complex Wavelet Structural Similarity(CW-SSIM) index resulted in a better index than other methods such as Multi-Scale(MS) SSIM, and Feature Similarity(FS) SSIM, across fabric specimen images. A correlation analysis of the similarity index based on an image analysis and a similarity evaluation by panel members was also implemented.

Those records indicate that Jik-geum Hyoong-bae fabric was imported from China and its period was during the fourteen and fifteen century. Gold threads used in three Jik-geum Hyoong-bae artifacts were all wrapped gold thread and gold thread of Danryeong from Young-dukdong, Yong-in, did not have a base, but instead the gold foil itself was attached to the silk cord. Such form of artifact had never been discovered before in Korea. Wrapped gold thread of Seoknamdong's basis was presumably bamboo paper. Three Jik-geum Hyoong-bae have the same weave structure. The ground is woven in a warp-faced 5-end satin weave. The pattern is brocaded with supplementary gold wefts. Supplementary gold wefts are composed of 1/4 twill binding by the odd number pairs of warps within every group of 10 pairs of warps. All of the Jik-geum Hyoong-bae textile were designed and weaved according to the overlapped collared costume's structure. This is also known as 'Jik-seong-pil-ryo'. One symmetric collared jacket excavated in Seok-namdong, Incheon, only has the right half of Hyoong-bae in the front. This is because symmetric collared jacket was made from overlapped collared costume. Tiger and peacock are the main patterns of Jik-geum Hyoong-bae which have realistic and free screen composition and this shows a huge difference to the later generation's standardized Hyoong-bae pattern.

In this paper, various tow parameters such as equivalent tow thickness, amplitude of longitudinal tow and tow intervals were investigated and compared with each other by using microscopic observation to find out the exact deformation patterns between both directions of the fabric structure (Longitudinal and Transverse Directions). Specimens for the observation were taken from draped helmet which is made of fabric composite (Five Harness Satin Weave). From the observation results, it was found that there are different deformation pattern between tow directions and effect of geometric condition on the deformation of the fabric materials during draping process was verified.

조선 말기 방한용 깔개인 모담(毛毯)이 창덕궁 성정각의 해체 공사 중 발견되었다. 문헌기록에 비해 현전하는 조선시대 모직물 유물이 많지 않아 유물로서 가치가 높다. 특히 1907년 창덕궁 성정각을 수리한 기록이 있어, 모담은 19세기 말 또는 20세기 초에 제작된 것으로 생각된다. 출토 모담은 자적색 계열의 바탕 직물로 위에 황색, 홍색 등으로 선염한 색사를 표면에만 삽입하여 문양을 시문하였다. 모담의 식서부분은 S연의 면사가 확인되었으며, 지경사는 Z연의 황마사, 지위사는 S연의 황마사, 문경사는 S연의 모사를 사용했다. 특히 무늬는 루프파일의 색사로, 색사의 경계면에서 일부 컷 파일이 확인되나 지위사로 고정되어 표면에 거의 드러나지 않는 다. 황마사와 모사를 사용한 것은 18세기 중엽 유럽의 브뤼셀 카펫의 영향을 받은 것으로 짐작된다. 모담의 문양을 밝히는 데 한계가 있으며 다만 문양이 부분적으로 반복됨을 알 수 있다. 이상의 연구내용을 도출하기 위해 문헌과 회화자료 외에 현미경 분석, 적외선 분광분석을 실시하였다. 또한 유물에 사용된 염료를 밝히기 위해 색도측정을 토대로 자외-가시광 분광분석을 실시하여 천연 염색한 직물 샘플에 대한 교차분석을 시도하였다. 그 결과 모담의 녹색 모사는 쪽을 사용하지 않았으며, 자적색의 바탕조직은 소목으로 염색한 것으로 추정할 수 있다.

This research was designed to compare clothing fabric images between on- and off-line by fabric types and its characteristics. 125 subjects who have a fashion design major evaluated the fabric image of various 16 kinds of specimens on- and off-line. Frequency, x2-test, t-test, and Pearson correlation were used for statistical analysis by SPSS WIN 11.0. The results of this study are as follows: 1. The advantage of on-line shopping includes low price and purchasing convenience, etc. On-line shoppers mostly purchase clothing items, such as T-shirt and slacks. In most cases, texture of fabrics provides a main cause for the shoppers' discontentment with internet shopping. 2. The results of t-test for the difference of the evaluation score show that plain or pile weave and highly thick or thin fabrics-for example, Organdy, Corduroy, Nylon Taffeta, Plush, etc.-have a large difference between on-and off-line image. On the other hand, medium-thick twill weave-for example, Tweed, Flannel, etc.-or patterned weave-Chiffon, Dobby fabric, etc.-shows a small difference. 3. The results of correlation of the evaluation score indicate that wool twill fabrics like Tweed, Saxony, and Polafleece show a high correlation between two kinds of evaluation score. In texture preference, no correlation exists between on-line and off-line. 4. With an analysis on fabric image evaluation by fabric characteristics, smooth, shiny pink Satin was found the most positively-evaluated item in all evaluation fields except in pattern preference and individuality. On the other hand, thick olive green Corduroy was evaluated most negatively in the fields of elegance, luxury, and feminine. 5. When compared with real ones, thin fabrics provide a different on-line fabric image. For example, Nylon Taffeta and Organdy were evaluated positively on-line because of luster and pastel tone color. However, lusterless uneven cotton Seersucker was evaluated negatively. 6. Real fabrics preference is more negative than on-line ones. In addition, patterned or unique fabrics display a high agreement between the two kinds of images.

This study is purposed to provide new idea for developing high value added fashion goods by studying relief effects of fashion design. Based on prior researches, various ways to give relief effects were searched and then modern fashion design cases were looked for which were referred to fashion-related magazines and collection-related internet sites since the late 1990s. The ways for relief effects are weaving, industrial finishing, sewing technique. Weaving techniques are about fancy yarns, variation of weaving structure, pile weave. Industrial finishing techniques which can make relief effects are embossing, heat-setting, shearing, pliss, burn out, flocking. Sewing techniques are quilting, pleats, embroidery, slash, attachment in accordance with the way to produce relief effects. The forms of relief effects are tactile pattern that cannot be seen in the distance, subtle relief pattern which is more three-dimensional than tactile pattern, rhythmical relief pattern, sculptural pattern, and deep-volumed pattern. The present research can provide practical data for design by studying techniques of relief effects and collecting and arranging design cases that have been sporadically carried out. The study on relief and unique surface effects can be a way to effectively stimulate and express emotions of modern people with various taste and individuality.
