Abstract

In this paper, porous non-woven fabrics were prepared using short fibers, which are by-products of hemp fibers, and evaluated the material properties for cushioning applications. The eco-friendly process using only water and the conventional process using sodium hydroxide were applied to produce the pulp for fabricating non-woven fabrics, respectively, and the compressive resistance, short-term and long-term resilience, and rebound elasticity characteristics were compared to evaluate the suitability of cushion materials. It has been found that porous nonwovens made from hemp fiber by-products, using an environmentally friendly pulping process, have the same or better properties as cushioning materials than nonwovens made from sodium hydroxide.


이 논문은 헴프 섬유 부산물인 단섬유를 이용하여 다공질 부직포를 제작하고, 쿠션용 재료 특성을 평가하였다. 부직포 제조를 위한 펄프 제작에 물만 사용한 친환경 공정과 가성소다를 이용한 기존 공정을 각각 적용하였으며, 쿠션용 재료의 적합성 평가를 위하여 압축 저항성, 단기 및 장기 복원력, 반발 탄성 특성을 비교하였다. 친환경 펄프화 공정을 적용하여 제작한 헴프 섬유 부산물 다공성 부직포가 가성소다를 이용한 부직포보다 동등 이상의 쿠션용 재료 특성을 가짐을 확인하였다


Keywords: 헴프(Hemp), 부산물(By-product), 펄프(Pulp), 부직포(Nonwoven), 쿠션(Cushion)
