Abstract

The invention relates to hot-wet comfortable polyester-fiber draw texturing yarns (DTYs) for winter, and a preparation method of the DTYs. The preparation method comprises the steps of metering spinning melt, extruding by using a composite spinneret, cooling, oiling and winding to obtain polyester pre-oriented yarns (POYs); enabling the POYs to pass through a yarn guide pipe and a network, stretching under the condition of heating, carrying out false twisting and heat-setting, and molding by winding so as to obtain the hot-wet comfortable polyester-fiber DTYs; the material of the DTYs is polyester with a dispersed matting agent; the thermal resistance and moisture resistance of knitted fabric made from the DTYs are respectively more than or equal to 0.16m<2>.DEG C / W and less than or equalto 12Pa.m<2> / W; the composite spinneret is provided with a cross-shaped spinneret orifice and a double-cross shaped spinneret orifice; the ratio of the micropore length of the cross-shaped spinneret orifice to the micropore length of the double-cross shaped spinneret orifice is equal to a product of the ratio of the equivalent diameter and a coefficient K, wherein the value range of the coefficient K is 0.97-1.03; an oiling agent for oiling contains crown ether, and the content of the crown ether is 67.30-85.58wt%. The preparation method provided by the invention is simple, and the obtained hot-wet comfortable polyester-fiber DTYs are excellent in hot-wet comfort performance.

Description

technical field [0001] The invention belongs to the field of fiber preparation, and relates to a DTY yarn of winter heat-humidity comfortable polyester fiber and a preparation method thereof. Background technique [0002] With the improvement of people's living standards, people's requirements for fabrics are getting higher and higher. While pursuing fashionable and elegant clothing, they also require clothing to be comfortable to wear. Comfort means that fabrics can meet people's physiological needs when they are in contact with people in the wearing environment. , Heart needs, the most important thing about fabric comfort is heat and humidity comfort, heat and humidity comfort refers to the fabric maintains a constant body temperature between the heat and moisture transfer between people and the environment, and creates good conditions for the normal physiological functions of the human body, so that The human body maintains a sense of comfort. The heat and humidity comfo...
