Wool/흡한속건 PET 혼방사를 이용한 편성물의 물리적 특성

Abstract

Recently, leisure time of consumer have increased and the market of outdoor fashion products in daily life is expanding. Therefore, it is necessary to develop knitwear materials for the textile fashion industries. 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 blended yarns mixed with wool fiber and quick-drying PET fiber(fiber length 51mm) were made by manufacturing process of woolen yarn. The wool fiber/quick absorbing-drying PET fiber spun yarns were prepared with different mixed ratio(wool fiber : quick absorbing-drying PET), 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 blended yarns(10.7～11.5 Nec) and spandex(40 de). On the evaluation of fineness, tensile strength and evenness(U%) of the spun blended 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 wool/quick absorbing-drying PET fiber spun blended yarn and its knitwear can contribute to the satisfaction of consumer's emotions and extension of knitwear market.
