본 연구에서는 생체모방기술을 응용하여 감성의류용 구조발색사를 방사하고, 이를 사용하여 직물을 제직 감량 가공하여 이들의 발색성 및 촉감 물성을 측정하여 감성의류용 용도의 적용성을 확인하여 다음과 같은 연구결과를 얻었다. 삼각단면을 가진 37층의 폴리에스테르와 나일론을 교호로 적층한 구조발색사의 방사조건을 확립하였으며, 이 세 가지 사의 발색성을 multi angle spectro-photometer로 확인하였다. 그리고 이 사들로 제직한 구조발색 직물 세 가지의 겉보기 색차와 반사율을 분석한 결과, 700nm에서 400nm까지의 파장에서 발색성을 확인하였다. 또한, 직물의 밀도와 조직이 다른 세 가지 구조발색 직물을 제직하고 감량 가공 처리하여 직물 역학특성치에서 촉감을 측정한 결과, $100^{\circ}C$, 60분 감량 처리한 시료가 최적설계(194ends/in ${\times}$ 105picks/in) 및 감량 조건임을 확인할 수 있었다. 그리고 감량 처리 시 온도와 처리시간 증가에 따라 감량률이 13%에서 최대 23%까지 증가함을 확인할 수 있었다. 이때 직물의 신축특성, 굽힘강성 및 전단강성은 감소하며 압축특성은 증가하는 현상을 보였다. 그리고 최적설계조건인 1번 직물시료를 $100^{\circ}C$, 60분 감량 처리할 때 촉감이 가장 우수하며 일본 몰포 직물보다 더 우수한 촉감치를 얻었다.

The polyester fabrics were treated with the chitosan with various solubility in optimized treatment condition. The treatment method was discussed to be a high functional finishing for the polyester fabric to obtain the high moisture absorption and anti-microorganism property by evaluating the effect of the chitosan purification method on the yield and anti-microorganism property of the chitosan. On the other hand, soluble polyurethane was added to the chitosan treatment solution and/or plasma pretreatment was done. The addition of soluble polyurethane give a high add-on ratio as well as a linen like effect of treated polyester fabric. The results were as follows: 1. In the treatment of polyester fabric by the chitosan solution, a soluble PU resin and low temperature plasma treatment were done to obtain high binding force between the fabrics and the chitosan. The add-on rate and the moisture absorption ratio of the fabrics treated with the chitosan-PU after treated with the plasma slightly increased more than those of the fabrics treated with the chitosan only. 2. Anti-static property of the fabrics treated with the chitosan decreased rapidly with increasing of the chitosan concentration. The washing fastness of the fabrics treated with the chitosan-PU after treated with the plasma was better than those of the fabrics treated with chitosan only. The wrinkle resistance of the treated fabrics decreased constantly with the concentration of the chitosan. The bending rigidity of the treated fabrics increased greatly. On the treatment of polyester fabric under optimum condition, the microorganism reduction rate kept above 90％ after 10times launderings. 3. As the polyester fabrics which has flat yam was used as a weft yams were treated with the chitosan-PU as give a functional finishing effects such as durability, moisture absorption, anti-static and anti- microorganism property. Treated polyester fabric showed a good functional finishing effect and a linen like property.
