Abstract

In this work, the thermal, antibiotic properties and far-infrared emissivity of fluorinated illite embedded polypropylene non-woven fibers (f-illite/PP fibers) were investigated in the presence of 0, 1, 3, 5 and 7 wt% illite powders. The thermal properties of f-illite/PP fibers were studied by thermogravimetric analysis (TGA). Their antibiotic properties were examined by Staphylococcus aureus and Klebsiella pneumoniae test. Their far-infrared emissivity was also investigated by Fourier transform infrared spectroscopy. From the experimental results, thermal, antibiotic properties and far-infrared emissivity of f-illite/PP fibers were improved by increasing fluorinated illite contents and the property values of 5 wt% f-illite/PP fibers were increased remarkably by about 10.3, 41.2 and 9.8% respectively in comparison with PP non-woven fibers having no fluorinated illite additive. This result was interpreted as the development of interfacial adhesion force between the polymer chains due to the fluorination of illite power.

본 연구는 폴리프로필렌 수지에 불소화된 일라이트를 함량별로 첨가하여 제조한 일라이트/폴리프로필렌(PP) 부직포의 열적 특성, 항균성, 원적외선 방사율을 고찰하고자 하였다. 불소화 일라이트 첨가 폴리프로필렌 섬유의 열적 특성은 열중량 분석을 사용하여 조사하였다. 그 항균 특성은 황색포도상구균과 폐렴간균의 균주 실험으로, 원적외선 방사율은 퓨리에 변환 적외분광법을 사용하여 알아보았다. 그 실험결과, 일라이트/PP 부직포 섬유의 열적 특성 및 항균성, 원적외선 방사율은 불소화 일라이트의 함량이 증가할수록 증가하였고, 특히 불소화 일라이트 5 wt% 함유 PP 부직포 섬유의 경우가 일라이트를 함유하지 않은 PP 부직포에 비해 각각 10.3, 41.2 및 9.8%로 크게 증가하였다. 이는 일라이트의 불소화로 인하여 고분자 사슬 분자 사이의 계면결합력의 향상 때문이라 판단된다.
