한지 테이프사와 필라멘트사를 이용한 합연사 및 편성물의 특성 변화

Abstract

Although Hanji yarn is prepared with staple fiber like manila hemp and paper mulberry fiber as raw materials, it is classified into a filament yarn. Generally the texture and appearance of Hanji fabric is unique to the touch and hard to produce a fuzz, respectively. However, due to no elongation, coarse surface, and stiffness of Hanji yarn, breakage of the yarn happens frequently during the knitting process. In order to prevent cut-off and increase flexibleness of Hanji yarn in knitting process, in this study, four types of ply yarn with Hanji tape yarn and filament yarn were prepared. Comparing with Hanji tape yarn or Hanji yarn, knitting efficiency of the ply yarns increased since these yarns have good tensile property, smooth and bulky twist formation. Especially the ply yarn showed increase in breaking stress and strain and decrease in initial modulus, as compared with Hanji tape yarn. The initial modulus of dyed ply yarn decreased much more. Therefore, the yarn is desirable for a good knitting process and so the selection of proper yarn and knitting method is important factor depending on end-uses such as underwear, socks, outer garment, and home textile. The application of ply yarn and dyed ply yarn are to help manufacturing excellent quality of Hanji knitted fabrics.
