섬유소재의 미세먼지 오염도 평가 방법 개발에 관한 연구

Abstract

Recently, functional clothes that can reduce deposition and/or penetration of fine dust have been developed. However, there are no methods to quantitatively evaluate the performance of these clothes. In this study, wedeveloped a method to contaminate a fabric using fine dust and established an approach to quantitatively assessthe degree of particle contamination on the fabric surface. Silicate powder was chosen as the particle to simulatefine dust because silicate particles are fluorescent under UV light; therefore, they can be distinguished from anycolor of non-fluorescent fabric surface. A camera with a high-resolution lens system was used to scan thesurface of the contaminated fabric surface, and the degree of particle contamination of the fabric surface wasanalyzed in terms of the pixels corresponding to the area of the fabric surface contaminated by silicate particles. Finished or unfinished nylon fabrics as well as cotton fabrics were contaminated with silicate particles, and theirsurfaces were scanned using the established camera. The proposed assessment method was found to be useful forquantitatively comparing the degree of particle contamination of the fabrics
