제목 Novel Recycling Technology of Ultra-fine Fibrous Materials
초록 Ultra-fine fibers are spun by expensive fiber spinning technology using special spinnerets. Ultra-fine fibrous materials has attracted considerable attentions because of their potential applications as high performance wiping cloths, water absorption, sound proofing materials and moisture transfer sporting good[1-2]. However, production expense of ultra-fine fibers is 5 to 7 times higher than general textile materials. Therefore, ultra-fine fibrous material waste and scrap should not be dumped and re- extruded to save natural resources. Accordingly, it is important to develop novel recycling technology. The objective of this research is to develop cost-effective recycling process to produce multi-functional ultra-fine fibrous material in terms of the development of garnetting and carding machines for ultra-fine fibrous material waste and scrap. The textile fabrics consisting of low melting polyester 20 wt% and recycled textile scrap were prepared by thermal bonding with bonding plate. Recycled ultra-fine fibers exhibited higher sound absorption value compared with general polyesters. The efficiency of sound absorption for recycled ultra-fine fibers increased with decreasing diameter of component fibers, which was attributed to the reduction of air permeability. The water and oil absorption values of recycled ultra-fine fibrous materials were higher than those of general wiping cloths. Recycled ultra-fine fibrous nonwoven was measured in terms of changes in tensile strength. The efficiency of the anti-static of the samples significantly improved after treating with nonionic anti-static agent. We measured the antibacterial activities according to concentration of nanosilver. Recycled ultra-fine fibrous nonwoven treated with nanosilver at all concentration showed 99 % of bacterial reduction. It is expected that high performance and cost-effective textile products can be developed using recycled textile scraps, thereby realizing the application as acoustic absorbents and wiping cloths.
