Abstract

The invention relates to a DTY yarn of hot and humid polyester fiber for summer use and a preparation method thereof. The preparation method is as follows: measuring the spinning melt, extruding it through a composite spinneret, cooling, oiling and winding to obtain a POY yarn , POY yarn is made of hot and humid comfortable polyester fiber DTY yarn for summer through wire guide tube, network, heating stretching, false twisting, heat setting and winding molding. The material is polyester dispersed with matte agent. The wicking height of the knitted fabric is ≥160 mm, the evaporation rate is ≥0.24 g / hour, and the composite spinneret is equipped with cross-shaped spinneret holes and circular spinneret holes at the same time. The micropore length ratio is equal to the product of the equivalent diameter ratio and the coefficient K, and the value range of the coefficient K is 0.97-1.03. The oil agent for oiling contains crown ether, and the crown ether content is 67.30-85.58wt%. The preparation method of the invention is simple, and the obtained fiber has excellent heat and moisture comfort performance.

Description

technical field [0001] The invention belongs to the field of fiber preparation, and relates to a polyester fiber DTY filament for summer heat and humidity comfort 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 ...
