Measuring Fiber Orientation in Nonwovens. Part I : Simulation

Research on the measurement of fiber orientation in nonwoven fabrics developed simulation models. Fiber orientation in nonwoven fabrics is an important characteristic because of its direct influence on fabric properties. In the development of simulation models, the research examined the applicability of image analysis algorithms in the ch..

A new evaluation system for nonwoven fabrics using image analysis technique: coverstocks, filters, and interlinings

This paper describes an evaluation method for nonwoven fabrics using an image analysis technique. Nonwoven fabrics used for coverstocks, filters, and interlinings were used for this study. They were made from polyester, polyethylene, polypropylene, and rayon using chemical, meltblown, spunbond, and thermal bonding system. Three properties..

부직포에 적용할 수 있는 새로운 수용성 폴리비닐알코올섬유

이 보고는 대삼(구라레)의 Index회의 (1996년, Feb.,)에서의 강연을 요약한 것이나, 보고된 섬유의 개요는 섬유가공., 48, 276 (1996)이나 섬유학회예고집 (IDPIO)에 소개되어 있다. 이전부터 사용되고 있는 수용성 폴리비닐알코올(PVA)섬유로는 습식방사법으로 제조되는 제지용 단섬유나 방적용 단섬유가 있다. 단섬유의 상호접착성과 관련하여 80℃이하의 온도에서..

면/셀룰로오스 아세테이트 부직포의 생분해성과 인장특성

환경 친화적인 부직포 중의 하나는 면/셀룰로오스 아세테이트(CA) 혼방품을 열 캘린더로 처리하여 만든 부직포이다. 본고에서는 이 섬유의 생분해성과 부직포의 인장특성에 초점을 맞추어 검토하였다. 면은 편안하고, 흡수성이 좋으며, 생분해성이 있기 때문에 부직포의 기본 섬유중의 하나이다. 한편, CA는 열가소성 및 친수성이 있고, 동시에 셀룰로오스 개질물질..
