Abstract (en)
Disclosed are an improved polyester fiber capable of attaining a heavy shade dyeing with a fast color by dyeing with a disperse dye at a temperature of 95 DEG C or less and a piece dyed fabric of a polyester fiber composite containing therein a fiber selected from a group consisting of a cellulosic fiber, wool fiber, silk, acetate fiber, polyamide fiber, stretch fiber. The improved polyester fiber having a peak temperature of the loss tangent ranging from 90 to 108 DEG C and composed of a copolymerized polyethylene terephthalate comprising: from 1.5% to 4.5% by weight of polyethylene glycol having a molecular weight ranging from 500 to 4000; and from 9% to 6% by weight of adipic acid in a ratio satisfying 1.3 </= % by weight of adipic acid/% by weight of ethylene glycol </= 6. The polyester fiber has a capability of being dyed at a temperature of 95 DEG C or less with a disperse dye, and the dyeing exhibits a superb color fastness to dry-cleaning, color fastness to light and thermal properties. Especially, the polyester fiber exhibits a balanced exhaustion of a dye combination in practical dye combination dyeing, and black dye dyeing can be carried out at 95 DEG C. Accordingly, in the above-mentioned fabric of fiber composite containing non-polyester fiber, a piece dyed fabric, with vivid color, of a polyester fiber composite in which any specific property of a mixed non-polyester fiber can be provided by a very productive means.
