초록
20세기의 자동차는 엔진의 주역할인 파워, 스피드를 중요시 하였으나, 소득수준의 향상에 따른 Well-being Trend의 확산 및 환경문제의 대두로 인해 쾌적성, 안락성, 안정성, 환경성 등을 중요시 하고 있다. 자동차용 Sub-Mat는 바닥 카펫 관리의 편의성 및 안락성 등을 위해 부가적으로 설치하는 매트로, 현재 자동차용 Sub Mat의 Backing 소재는 재생고무, PVC 등이 사용되고 있지만, 재생고무 Sub-Mat는 흡음성능이 나쁘고 PVC Backing Sub-Mat는 중량이 매우 커 연비 면에서 불리하고, 유해물질이 다량 포함되어 있어 점차적으로 사용이 어려워질 전망이다. 본 연구에서는 나일론 표피 파일 층, PE 접착 층, Backing(PET fiber)을 합포하여 제작한 sample1과 PET표피 파일 층, PE 접착층, Backing 부직포 층(PET)을 합포하여 제작한 sample2, Backing층을 PVC로 요철을 부여하여 제작한 sample3의 Non-Slip성을 평가하였으며, 이에 따른 접촉면의 변화를 비교 평가하였다.
Abstract
Automotive sub-mat carpet for convenience and comfort of floor administration is additional supplemented floor mat. Sub Mat Backing of the current vehicle's materials reclaimed rubber, PVC, etc. are used, but secondary rubber and PVC Backing have bad sound absorption. Also rubber is heavy too. Contact surfaces between PET staple fiber, PET non-woven, PVC backing and car's floor carpet was measured the coefficient of friction for each sub-mat's non-slip evaluation. A surface of PET non-woven sub-mat has the highest coefficient of friction. Each of sample was observed by optical microscope the contact surfaces before and after. Contact surfaces of PET staple fiber sub-mat was changed increasingly to non-woven. This fact is shown that the sub-mat would be tangled between its contact surface and top of the floor carpet. It is expected to be highly non-slip. In case of PET non-woven sub-mat had not different for contact surfaces between before and after. And PVC backing was shown lower non-slip than other samples. The result of optical microscope and coefficient of friction is seems to be related.
