Abstract

This study investigated the physical properties of aramid/nylon ATY and aramid ATY for protective garments according to the aramid and nylon characteristics fed on the core and effect components of air jet texturing equipment. Tenacity decrease of aramid ATY was much more higher than that of nylon ATY because of slick of aramid filament surface. Tenacity of aramid/nylon ATY was most affected by the tenacity of nylon on the effect component of ATY. Breaking strain of nylon ATY was two times higher than that of nylon before air jet texturing, then, in case of aramid ATY and aramid/nylon ATY, were 5.9-6.7 times higher than those before air jet texturing. Initial modulus decrease of aramid ATY showed 86.5% of initial modulus of aramid before air jet texturing, then aramid/nylon hibrid ATY showed arithmetic average value of initial modulus of aramid and nylon ATY. Wet and dry thermal shrinkages of aramid/nylon hybrid ATY were dominated by those of nylon filament on the effect component of ATY.

본 연구는 에어제트텍스쳐링 장치에서 공급되는 코어사와 이펙트사인 아라미드와 나일론의 구성이 방호의류용 아라미드/나일론 ATY와 아라미드 ATY의 물성변화에 대한 연구이다. 아라미드 필라멘트 표면의 매끄러움 때문에 아라미드 ATY의 강도 저하는 나일론 ATY에 비해 훨씬 높았다. 아라미드/나일론 ATY 강도는 ATY의 이펙트사인 나일론의 강도에 가장 영향을 많이 받았다. 나일론 ATY의 절단신도는 에어제트텍스쳐링 이전의 나일론에 비해 두 배정도 높은 값을 나타내었으며, 아라미드 ATY와 아라미드/나일론 ATY는 에어제트텍스쳐링 이전에 비해 5.9~6.7배 정도로 높았다. 아라미드 ATY의 초기탄성률은 아라미드의 에어제트텍스쳐링 이전에 비해 86.5%정도 감소하였으며, 아라미드/나일론 ATY의 초기탄성률은 아라미드 ATY와 나일론 ATY 초기탄성률의 산술평균치를 나타내었다. 아라미드/나일론 하이브리드 ATY의 습 건열 수축률은 나일론의 영향을 받음을 알 수 있었다.
