느릅나무껍질로부터 추출한 염액을 이용하여 면, 마, 모, 견, 나일론 섬유와의 염색성을 조사하였다. 각 섬유와의 최적 염색조건을 설정하였으며 합성매염제와 천연매염제를 사용하여 염색성에 미치는 매염제의 효과를 검토하였다. 또한 느릅나무껍질로 염색한 각 염색포의 세탁견뢰도와 일광견뢰도를 살펴보았다.실험결과 느릅나무 염색의 최적조건은 욕비 1: 40, $80^{\circ}C$, 60분 이었으며 견과 나일론이 가장 잘 염색되었다. 견, 모, 나일론의 경우 매염제의 처리에 의해 염색성이 향상되었으며 매염제의 종류에 따라 색상이 크게 변화되어 다양한 색상을 얻을 수 있었다. A natural dyeing makes fabrics look unique and elegant which cannot be obtain by synthetic dyestuffs. The natural dyestuffs are harmless to human, and it is easy to get them. Also, the natural dyestuffs are environmentally frendly, which is the anther merit for natural dyeing,We investigated dyeability with several fabrics (cotton, wool, ramie, silk and nylon) using an elm bark. We mordants(natural and synthetic). Also, colorfastness in dyed fabrics was estimated by laundering and light. The optimum condition of dyeability in elm bark was 60 min as time, $80^{\circ}C$ as temperature and 1: 40 as bath ratio. The dyeability in silk and nylon was the best among the sample. The treatment of mordants improved the dyeability and colorfastness in silk, wool and nylon. We obtain various color by the mordants.

양말의 염색견뢰도에 영향을 주는 땀, 세탁의 인자를 선택하여 재질별, 성별착용에 따른 양말의 염색 견뢰도와 오염도 및 내구성 실험을 행하였다. 반복된 착용과 세탁에 의해 양말의 염색견뢰도는 면 100%의 것이 가장 우수하게 나타났으나 수축은 혼방제품과 면 양말에서 크게 나타났다. 성별착용 실험결과 남자가 착용한 것이 여자의 것보다 오염도, 수축, Pill 등이 훨씬 크게 나타나 내구성이 떨어지는 것으로 밝혀졌다. We were investigated the change of shrinkage, pilling, tensile strength, color fastness and staining of Cotton, Nylon, Cotton/Nylon(60/40) socks after wearing and washing. From the experiment we found that color fastness of the color socks decreased corresponding to the frequency of wearing and washing. Our results showed that color fastness in the case of Cotton is best among them. Shrinkage was significant in Nylon/Cotton and Cotton socks. In the experiment of male and female socks, male showed a greater evidence of staining, shrinkage and pilling than female.

This study examined 12 types of towels with differing fabric material, function, quality, printing, pile length, twist, etc. from a towel company which manufactures and distributes products domestically. After 3 months of use by consumers, a consumer satisfaction survey was administered and results analyzed. Four types of towels were assigned to each group and the towels were used every day for 3 months. Participant feelings after using the towel for the first time and after using it for three months were investigated. The questionnaire consisted of 26 questions on a 5-point Licket-type scale. The first 13 questions measured perceptions of absorption, touch, fine fiber loss, contamination, deformation, drying speed, and design. Other questions compared differences between the two towel types in terms of their material, function, quality, printing, pile length, and degree of twisting. Results showed that, with regards to weight, consumers preferred towels between 130~150g and a thickness of around 1.7~1.8mm. The bamboo towel was considered superior to the cotton towel in terms of sense of touch and did not happen linter after washing. The antibacterial towel was considered better than the cotton towel in terms of absorption but in terms of contamination, participants felt the antibacterial towel became dirty more easily than the cotton towel. We thought that it might be influence of the color of towel. Low-quality towels became stiffer and misshapen more easily than higher-quality towels. But the study showed that the consumers did not perceive significant differences in the towels' quality. Printed towels became thinner and their color changed more with washing. The consumers preferred the design of jacquard towels to printed towels. Towels with short piles was happened more linter than the towel with long pile after washing. Non-twisted towel were better than the highly-twisted towel in terms of sense of touch and absorption but the non-twisted towel happened more linter after washing and became dirty more easily.

A comprehensive apparel CAD system performing automatic two dimensional garment pattern drafting, optimum allocation of patterns on the cloth, and the prediction of the final drape shape of designed garment putting on the human body was developed. The two dimensional garment pattern drafting is based on the concept of creating basic pieces from the formulated design script. For the accuracy as well as convenience of designing purpose, apparel CAD specific functions such as dart manipulation have been generated. Optimum pattern allocation algorithm has been developed based on the idea of minimizing the evaluation function which has the positions of the patterns as dependent variables, using the conventional pattern boundary checking algorithm during the allocation process instead of dividing patterns into fine grids. To predict the draped garment shape, we first divided designed garment pieces into fine quadrilateral elements using a specially designed mesh generator and assigned a sewing condition to make a three dimensional shape. Final shape is predicted in relatively short time considering the contact condition with human body, deformation, the weight of the garment pieces, and the surface texture of the cloth.
