아마혼방사와 스판덱스사를 이용한 28게이지 자카드 환편물 제조와 특성 평가

Abstract

To develop a new group of high-functional underwear and sportswear products, in this study, the jacquard circular knitted fabrics(28G) were manufactured with the rayon, hard twist cotton yarn, or cold polyester filament yarn such as contact-cooling fiber materials around spun blend yarn(linen/cotton, linen/rayon) and spandex filament yarn. The unique and desirable characteristics of linen fiber are cool-feeling, luster, antibiotic, abrasion resistance and thick-and-thin fiber bundles, which give texture to the knitted fabrics suitable for summer season. By processing steam heat treatment(105℃, 24min.) and decreasing yarn feeding speed to the 13rpm for LCY and RFY respectively, the knitting ability in the above-described yarns have been greatly improved. All of the knitted fabrics exhibited excellent surface appearance, tensile property, stretch, and color fastness of 4∼5 grade to washing, rubbing, and perspiration, except for sample No 4 and No 5, lacking of dimensional change in washing and drying. Also, the commercialization of the knitted fabrics was determinated by evaluation of knitting organization, knitting ability, mechanical property, color fastness, stretch, and dimensional stability. From the evaluation of appearance and other properties mentioned, the jacquard circular knitted fabrics were found to have the potential commercialization.
