한지사/필라멘트사의 합연사로 제조한 편성물의 물성 평가

Abstract

Since Hanji yarn breaks frequently in high speed knitting or weaving process, many types of ply yarn blended Hanji yarn are recently introduced. In order to prevent coarse surface and hard property causing breakage of Hanji yarn, the ply yarns with Hanji yarn and filament yarn were prepared. In this study, four different knitted fabrics were produced and their appearance, tensile property, shrinkage, color fastness, and deodorant efficiency were evaluated. To make mass production and enlarge specific end-uses of knitted fabrics using the ply yarns, in the present work, the fabrics were produced by circular knitting machine and these properties were studied. The knitted fabrics were a good appearance and tensile property of the fabrics showed much better values to the course direction. All of the fabrics were excellent color fastness of 4∼5 grade to washing, dry cleaning, rubbing, and perspiration. For color fastness to light resistance, the knitted fabrics with Hanji/nylon and Hanji/polyester ply yarns were 4 and 5 grade, respectively. By heat treatment such as tenter finish, the shrinkage of knitted fabrics were ±2.0% and less. The knitted fabrics showed an excellent deodorant efficiency to the ammonia gas. From the above mentioned results, the knitted fabrics can be applicable to the end-uses such as underwear, sportswear, and socks.
