양모/중공 PET 혼방사로 제조된 니트원단의 역학적 특성 연구

Abstract

Wool fiber is usually used for knitted fabrics such as sweaters and jerseys because of its excellent stretchability, warmth, absorption and waterproof, etc. In this study, the spun blend yarns mixed with wool fiber and hollow PET fiber(64mm) were made by manufacturing process of woolen yarn. The spun yarns were prepared with different mixed ratio(wool fiber : hollow PET fiber), 100:0, 70:30, 50:50, and 30:70. The knitted fabrics were also manufactured by knitting conditions(36 inch, 8.5 gauge) with the spun blend yarn and spandex. On the evaluation of fineness, tensile strength and evenness(U%) of the spun blend yarn, the spun yarn showed outstanding tensile strength and evenness with increasing the PET fiber content. Also, the tensile strength and bursting strength as well as mechanical properties using the KES FB system of the knitted fabrics were analyzed. The tensile strength, bursting strength and mechanical properties of knitted fabrics were appeared to good results with increasing the PET fiber content. Therefore, it is expected that the spun blend yarn(wool/hollow PET fiber) and its knitwear can contribute to the satisfaction of consumer's emotions and extension of knitwear market.
