Abstract

In this study, we reported the effect of porcine pancreas lipase treatment in the presence of a calcium chloride and Triton X-100 on moisture regain and wettability of PET fabrics. The moisture regain of PET fabrics in the presence of 0.5% surfactant showed a 1.5-fold decrease, compared to the absence of it. Triton X-100 acted as an inhibitor to porcine pancreas lipase hydrolytic activity. The moisture regain and wettability of porcine pancreas lipase treated PET fabrics improved when more than 10mM of calcium chloride was added to the treatment solution. Porcine pancreas lipase treatment caused voids and cracks on PET fabrics.

본 연구는 폴리에스터 직물에 리파제 처리시 첨가제에 따른 수분특성 변화를 검토하였다. 활성제(염화칼슘) 및 비이온 계면활성제(Triton X-100) 첨가가 수분율, 접촉각, 흡수속도, 표면형태변화에 미치는 영향을 비교, 분석하였다. 연구결과, 리파제 처리된 폴리에스터 직물의 수분율은 비이온 계면활성제인 Triton X-100 첨가시 현저히 감소하는 것으로 나타났다. 그러나 리파제의 활성제로 알려진 염화칼슘 첨가 시 폴리에스터 직물의 수분특성은 다소 증가하는 것으로 나타났다. 특히 리파제 처리 시 염화칼슘이 10mM이상 첨가된 경우 폴리에스터 직물의 수분특성이 증가되었다. 리파제 처리된 폴리에스터 직물의 표면관찰 결과, 섬유표면에 생성된 보이드와 크랙이 폴리에스터 직물의 수분특성 증가에 영향을 미치는 것으로 확인되었다. 이상의 결과를 통해, 폴리에스터 직물에 리파제 처리시 Triton X-100은 리파제의 활성을 저해하고, 염화칼슘은 리파제의 활성을 다소 증가시키는 것을 확인하였다.
