Embodiment 1

[0067] A summer hot and humid comfortable polyester fiber FDY yarn, the preparation method is:

[0068] (1) preparation of oiling agent for oiling;

[0069] Mix 2-hydroxymethyl-12-crown-4 with potassium dodecyl phosphate, trimethylolpropane laurate and sodium hexadecylsulfonate at room temperature and add to 12# mineral oil and uniformly stirred at 40°C for 2.5h to obtain an oil agent; the addition amount of each component is as follows in parts by weight: 5 parts of 12# mineral oil; 95 parts of 2-hydroxymethyl-12-crown-4; 12 9 parts of potassium alkyl phosphate; 2 parts of sodium hexadecyl sulfonate. The content of crown ether in the prepared oil is 85.58wt%. The oil has excellent high temperature resistance. After heat treatment at 200°C for 2 hours, the thermal weight loss is 9wt%. The viscosity of the oil is low. When the kinematic viscosity is 29.5mm 2 / s, the kinematic viscosity after the concentration of 10wt% emulsion is configured with water is 0.93mm 2 / s, the oi...

Embodiment 2

[0075] A summer hot and humid comfortable polyester fiber FDY yarn, the preparation method is:

[0076] (1) Preparation of oiling agent for oiling; 15-crown ether-5 and isomeric tridecyl alcohol polyoxyethylene ether phosphate potassium salt, trimethylolpropane laurate and sodium dodecylsulfonate are mixed at room temperature After mixing evenly, add it to 13# mineral oil and stir evenly at 52°C for 2 hours to obtain an oil agent; in parts by weight, the addition amount of each component is as follows: 10 parts of 13# mineral oil; trimethylolpropane lauric acid 5 parts of ester; 70 parts of 15-crown ether-5; 8 parts of isomeric tridecyl polyoxyethylene ether phosphate potassium salt; 6 parts of sodium dodecylsulfonate. The content of the crown ether in the prepared oil is 70.70wt%. The high temperature resistance of the oil is excellent. After heat treatment at 200°C for 2 hours, the thermal weight loss is 13.5wt%. The viscosity of the oil is low, at (50 ± 0.01) At ℃, the kin...

Embodiment 3

[0082] A summer hot and humid comfortable polyester fiber FDY yarn, the preparation method is:

[0083] (1) Oil preparation for oiling; 2-hydroxymethyl-15-crown-5 and potassium salt of tetradecyl phosphate, trimethylolpropane laurate and sodium pentadecylsulfonate After mixing evenly at room temperature, add it to 11# mineral oil and stir evenly at 48°C for 3 hours to obtain an oil agent; in parts by weight, the addition amount of each component is as follows: 8 parts of 11# mineral oil; trimethylolpropane lauryl 10 parts of acid ester;

[0084] 2-Hydroxymethyl-15-crown-585 parts; Tetradecyl phosphate potassium salt 11 parts; Sodium pentadecylsulfonate 5 parts. The content of crown ether in the prepared oil is 70.83wt%. The oil has excellent high temperature resistance. After heat treatment at 200°C for 2 hours, the thermal weight loss is 11wt%. The viscosity of the oil is low. When the kinematic viscosity is 30.1mm 2 / s, the kinematic viscosity after the concentration is 1...

Abstract

The invention relates to a summer heat and humidity comfortable polyester fiber FDY yarn and a preparation method thereof. The preparation method is as follows: measuring the spinning melt, extruding through a composite spinneret, cooling, oiling, stretching, heat setting and Summer hot and humid comfortable polyester fiber FDY yarn is obtained by winding, the material is polyester dispersed with a matting agent, the wicking height of the woven fabric made by it is ≥ 135 mm, and the evaporation rate of the woven fabric is ≥ 0.22 g / Hours, the composite spinneret is equipped with cross-shaped spinneret holes and circular spinneret holes at the same time, and the ratio of the micropore length of the cross-shaped spinneret holes to the circular spinneret holes is equal to the product of the ratio of the equivalent diameter and the coefficient K, and the coefficient The value range of K is 0.97-1.03, and the oil agent for oiling contains crown ether, and the content of crown ether is 67.30-85.58wt%. The preparation method of the invention is simple, the obtained fiber has excellent heat and moisture comfort performance, and has promising application prospects.

Description

technical field [0001] The invention belongs to the field of fiber preparation, and relates to a summer heat and humidity comfortable polyester fiber FDY 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 comfort o...
