폐기되고 있는 땅콩껍질로부터 재활용이라는 로하스 개념을 적용한 천연염색 자원개발 측면에서 땅콩껍질의 색소 추출을이용하여 나일론직물의 염색성, 염색 견뢰도와 더불어 기능성을 토하고자 하였다. 볶은 땅콩(학명 Arachis hypogaea)의 외피를 분리하여 땅콩껍질 5kg에 증류수 10L을 가하여 $100^{\circ}C$에서 120분간 환류시켜 색소를 추출 여과하였다. 매염제는 시약은 1급을 그대로 사용하였다. 시료는 KS K 0905에 규정된 염색 견뢰도 시험용 정련된 표준 나일론직물 사용 하였으며 염액의 욕비 1:50, 시간에 따른 염색조건, 염색온도, pH, 반복 염색성은 $100^{\circ}C$에서 90분씩 염색하여 건조하는 순서로 6회 반복 염색하였다. 염색온도가 높아질수록 시간이 길어질 수록황색이 점차 진해지며 온도 증가함에 따라 K/S값과 ${\Delta}E$값이 점차 증가함을 보여주고 있다.

In order to make an advanced dry-friction engineering material, wax-impregnated nylons were synthesized by anionic polymerization of $\varepsilon$-caprolactam in the presence of apraffin wax. DNX-125S, which has lowest melting point among four different kinds of waxs investigated, showed excellent miscibiility with $\varepsilon$-carprolactam and no effect on the polymerization reaction. Five different kinds of wax-impregnated nylons from of DNW-125S content 0% to 8% were synthesized and tested. Among the samples, wax-free nylon has the highest yield and tensile strength and hardness, while the specimen with2% wax has the largest elongationi and energy absorption to break. The wax-impregnated nylon with a wax content 6% showdd the smallest friction coefficient under slow sliding speed and low load. Bus as the sliding speeds were increased to high, thespcieimen with 8% wax has better friction property.

Nylon fabric was grafted for the purpose of the development of detergency against the hemoglobin as a protein soil. By free-radical producing chemical initiator systems the graft using acrylic acid(AA) as a hydrophilic vinyl monomer was performed to change surface energies in the presence of ammonium persulfate(APS) as an initiator and then acrylic acid grafted Nylon was treated with NaOH solution. The surface morphology for Nylon-g-NaAA with changing graft rate were studied by scanning electron microscopy (SEM) The properties of the Nylon such as diameter tenacity elongation contact angle and the hemoglobin removal were also investigated. The diameter of grafted Nylon fiber increased as the graft ratio increased. The tenacity of grafted Nylon also increased with increasing graft ratio up to 15% The elongation however decreased gradually according to graft, The contact angle decreased after graft and alkaline treatment. The amount of hemoglobin on the grafted Nylon increased in proportion to the graft ratio. Hemoglobin was easily removed from grafted Nylon while it was difficult to be removed from ungrafted Nylon. The detergency of hemoglobin for grafted Nylon decreased when the graft ratio exceeded 15% The removal of hemoglobin increased markedly with increasing hemoglobin content and revolution speed. Therefore the removal of hemoglobin was improved due to graft and alkaline treatment.

Conventional nylon wire cutting-type holding and release mechanisms (HRMs) are limited to securely hold the solar panel under launch environment as the size of the panel increases because the nylon wire is tightened directly on the surface of the solar panel. In this study, we proposed a nylon wire cutting-type HRM for 6U CubeSat's solar panel applying elliptic-shaped bracket with a Ball & Socket interface. The proposed HRM has the advantage of higher holding capability along in-plane and out-of plane directions of solar panel and simplicity in tightening process of nylon wire. The design drivers of structural design of CubeSat's solar panel with the proposed HRM were defined by structural analysis under launch loads. In addition, The design effectiveness of the proposed HRM was verified through the functional tests according to the thickness of nylon wire and the number of wire winding under various temperature conditions.

최근 나일론 세섬 신축소재를 이용한 초경량 직물은 에 많이 사용되어지는 Nylon직물은 DTY 20~40d 소재를 이용한 rib조직과 이중조직 설계기술 및 염색가공기술에 의한 것으로 이들 제품은 조직의 한계점(이중조직, Rib), 신축특성의 저하, 품질 저하의 문제점이 대두되고 있어 아직까지 본격적으로는 상용화되지 못하고 있는 실정이다. 국내외적으로는 Polyester를 이용한 잠재권축 사는 일정수준으로 기술개발 진행 되어왔으나 아직까지 나일론 세섬사의 잠재권축 소재의 기술개발은 전무한 실정이다. 따라서 본 연구에서는 스포츠/레저용 초경량 Nylon 박지에 적합한 자발신장 개념인 Nylon6 잠재권축 소재를 개발하기 위하여 26D수준의 side by side형인 nylon6/Co-Nylon의 구조와 물성을 조사 검토하여 이를 실제 현장에 자료를 제공하는 것을 목적으로 하였다.
