Abstract
For the development of worsted fabric composed of single yarns, four kinds of single yarn of about 40 Nm were spun using two types of the fibers having the fineness of 19.50 μ and 17.05 μ and two different the number of twist, respectively. Twenty-one worsted fabrics fiber fineness, yarn twist, fabric density and structure having different were prepared from size single yarns. the hand and garment performance of the fabrics were evaluated by KES and FAST system, respectively. The worsted fabrics of will structure had good THV values and were suitable for women's suit. And the fabrics of plain structure were good for women's thin dress. The effect of the fiber fitness on THV was less than the effects of other construction factors. All worsted fabrics showed poor wrinkle recovery in comparison with traditional worsted fabrics composed of two ply yarn. The relaxation shrinkage and the hygral expansion of these fabrics increased with decrease in the fiber fineness, but all of them located in the control zone given by the FAST manual. The fiber fineness was found to be one of the dominant factors in formability evaluation.
