Nonwovens have been widely used in various regions from the households to the industrial, agricultural and medical goods. Synthetic fibers have been used for source of nonwovens commonly because of their useful and economic properties. They are not only main factor causing environmental problems but also spend huge cost to renew the environmental disruption by them. Nonwovens must have both cost-competitiveness and environment-friendly property to be the desirable sources in 21th centuries. For meet these needs, it is suitable for the times that economical and environmentally-safe kenaf fibers would be used as raw materials of nonwovens. Kenaf and polyester fibers were blended in 4 types of ratio : 0/100, 20/80, 40/60, 60/40 were needle-punched. The nonwovens properties such as color values, surface appearance, strength, elongations, stiffness, moisture regain, water and oil absorbency, and electrification were tested. As the results, tensile and tear strengths, water and oil absorbency were maximum at 20/80 kenaf/polyester blend nonwoven, because of effecting by nonwoven structure and fiber properties. The moisture regain were increased according to kenaf were blended and the eletrification reduced in proportion to the kenaf fibers by chemical property of fiber composed nonwovens.

This study examines the dyeability, light fastness, washing fastness, and the antibacterial activity of chitosan and nano silver composite non-woven fabrics dyed with an extracted solution from Chrysanthemum Indicum Linn. The results show that an increase in the chitosan and nano silver percentage resulted in an increase in the $a^*$ values and $b^*$ values; however, the $L^*$ values decreased in the undyed condition. ${\Delta}E$ values of chitosan and nano silver composite non-woven fabrics were higher than cotton 100% non-woven fabrics in the dyed condition with an extracted solution from Chrysanthemum Indicum Linn, and mordant treatments influenced the chrominance change. In the dyed condition with an extracted solution from Chrysanthemum Indicum Linn, an increase in the percentage of chitosan and nano silver resulted in an increase of the K/S values. The dyeability of chitosan and nano silver composite non-woven fabrics increased by mordant treatments. The light fastness and washing fastness of the mordanted non-woven fabrics were better than the non-mordanted. For the antibacterial activity, the bacterial reduction rate of chitosan and nano silver composite non-woven fabrics was 99.9% to Staphylococcus aureus and Klebsiella pneumoniae.

Nonwoven fabrics have been widely used in various fields that include household, industrial, agricultural, medical goods, especially in the automobile industry. In this study, eco-friendly fiber materials were developed and investigated as a substitute material for polyester fibers in nonwovens. To make plant fiber bundles, stems of Indian mallow (IM), and Kuzu vine (KV) were retted; in addition, the non-cellulose component was partially removed. Plant fiber bundles and polyester fibers (P) were blended and needle punched to produce nonwovens. Five kinds of nonwovens were manufactured: P100 (Polyester 100%), IM10 (IM 10% and Polyester 90%), IM20 (IM 20% and Polyester 80%), KV10 (KV 10% and Polyester 90%), and KV20 (KV 20% and Polyester 80%). The color values, surface appearance, tensile strength, elongation, tear strength, abrasion strength, flexstiffness, moisture regain, water or oil absorbency, and static electricity of manufactured nonwovens are investigated. As the blended ratios of IM or KV increased, the brightness of nonwovens decreased compared to that of polyester 100%. Tensile strength, tear strength, abrasion strength, and flexstiffness of IM10 as well as KV10 were higher than those of P100, IM20, and KV20, resulting from the influence of the structure and properties of nonwoven fibers. Moisture regain and water or oil absorbency increased, while static electricity decreased in proportion to the amount of plant fibers. IM or KV and polyester blended nonwovens showed improved properties over P100 that could be substituted for P100 as a novel material for textiles.

리오셀직물은 면직물보다 강하고 습윤시 치수안정성이 높으며 우수한 드레이프성, 탁월한 광택, 소프트한 촉감 등 우수한 성능을 가지고 있어 최근 각광받고 있는 신소재 중 하나이다. 그러나 리오셀직물에 관한 연구는 섬유의 성질, 가공염색방법에 관한 것이 대부분으로, 적합한 봉제방법, 심지선정 등에 관한 연구는 찾아보기 어렵다. 이에 본 연구에서는 겉감으로 시판 리오셀직물 중 숙녀복 수트용으로 사용되고 있는 100% 텐셀직물과 65/35% 텐셀/면 혼방직물 각각에 대해 20수와 10수 모두 4종류를 선정하고 접착 심지로는 중량과 조직을 달리하는 시판 직물심지 5종류와 부직포심지 1종류를 선정하여, 리오셀 심지접착포의 접착심지와 리오셀겉감의 특성에 따른 외관적 성능과 역학적 특성을 측정한 후, 통계적 분석(t-검정, F-검정)에 의해 검정하여 다음과 같은 결론을 얻었다. 1. 리오셀 심지접착포의 드레이프성과 구김회복성은 접착심지의 구조에 영향을 받고, 강연성은 접착심지의 구조와 리오셀겉감을 구성하는 실의 변수에 영향을 받는다. 2. 리오셀 신지접착포의 인장특성중 WT는 리오셀겉감을 구성하는 실의 번수와 혼용률에 영향을 받고, RT는 리오셀 겉감을 구성하는 실의 번수에 영향을 받는다.
