Embodiment 1

[0027] Weigh 50 parts of terephthalic acid, 15 parts of sodium isophthalic acid-5-sulfonate, and 22 parts of ethylene glycol into the reaction kettle, and gradually raise the temperature to 220-230 o C undergoes a transesterification reaction. After the transesterification reaction is completed, 13 parts of polyethylene glycol with an average molecular weight of 4000, K 3 Al(C 2 o 4 ) 3 , an appropriate amount of ethylene glycol antimony catalyst and triphenyl phosphate stabilizer, and jade powder with an average particle size of 25nm equivalent to 1% of the total weight of the polyester, gradually warming up to 275 o C undergoes a polycondensation reaction. The obtained polyester is sliced ​​and granulated, and then melt-spun to obtain polyester fibers. Above-mentioned gained fiber is placed in 140 o Take it out after heat treatment in hot water for 15 minutes, and the measured fiber density is 1.32g / cm 3 .

Embodiment 2

[0029] 85 parts of hydrophilic cool feeling polyester fiber and 15 parts of cotton prepared in Example 1 were siro-spun to obtain 50S blended yarn. 93 parts of the obtained yarn and 7 parts of spandex are knitted to obtain a knitted fabric with a cloth weight of 135g / m 2 . After testing, the water absorption rate of the fabric is 250%, the wicking height is 171mm, the water evaporation rate is 0.32g / h, and the contact coolness coefficient is 0.21J / (cm 2 s).

Embodiment 3

[0031] 50 parts of hydrophilic cool feeling polyester fiber, 35 parts of tencel and 15 parts of bamboo fiber prepared in Example 1 were siro-spun to obtain 50S blended yarn. 95 parts of the obtained yarn and 5 parts of spandex are knitted to obtain a knitted fabric with a cloth weight of 140g / m 2 . After testing, the water absorption rate of the fabric is 245%, the wicking height is 161mm, the water evaporation rate is 0.20g / h, and the contact coolness coefficient is 0.19J / (cm 2 s).

Abstract

The invention discloses a method for preparing a hygroscopic and quick-drying cool feeling yarn. The hygroscopic and quick-drying cool feeling yarn is composed of hydrophilic polyester fiber 40 to 90wt%, cotton 0 to 15wt%, and regenerated cellulose fiber 0 to 60wt%. The yarn prepared by using the method for preparing the hygroscopic and quick-drying cool feeling yarn and the finally prepared fabric have the cooling effect, so that the wearer always feels both dry and cool, which overcomes the shortcomings of the fabric with only a single function. In addition, the yarn prepared by using the method for preparing the hygroscopic and quick-drying cool feeling yarn has permanent hygroscopic, quick-drying and cooling effects, and the hygroscopic, quick-drying and cooling effects cannot gradually decline with the increase of the number of washings as the yarn finished by a finishing agent.

Description

technical field [0001] The invention relates to a method for preparing cool-feeling yarn, more specifically, it relates to a method for preparing cool-feeling yarn of hydrophilic polyester fiber. Background technique [0002] The so-called cool fabric refers to a functional fabric that the wearer can feel cooler than ordinary fabrics. This cooling effect can be derived from the yarn with cooling effect, or from the finishing of the fabric. Although finishing is simple and convenient, the cooling effect obtained by finishing is not long-lasting. [0003] In order to obtain the cooling effect, the most direct method is to add functional powder with cooling effect to the fiber. For example, Chinese patent CN109402763A discloses a method for preparing cool-feeling fibers. The inventor added ore powder such as mica, jade, and Tai Chi stone to molten nylon 6 raw materials, and then spun to make cool-feeling fibers. Compared with the resin material constituting the fiber, the ab...
