Problems solved by technology

However, its hygroscopicity is extremely poor
[0005] However, the content of spandex in high-grade nylon / spandex knitted fabrics should reach more than 18%. Because spandex fiber molecules have no hydrophilic groups, and the molecules are tightly packed, it is difficult for water molecules to enter the interior of the fiber, so it has strong hydrophobicity. Poor moisture absorption performance, easy to generate static electricity and easy to stain, etc., poor wearing comfort, and limited application

Abstract

The invention provides a method for improving the moisture-absorption and sweating performance of a fatty polyamide fiber / polyurethane fiber fabric. The method comprises the following treatment processes in sequence: step 1, dip padding with a treating agent, step 2, drying, and step 3, baking. The treating agent is made from the following components: isophorone diisocyanate, poly(butyl acrylate), a micromolecule chain extender, organic acid, and epoxy resin. In the step 1, the use amount of the treating agent is 40-70 g / L. In the step 2, the drying temperature is 100-120 DEG C. In the step 3, the baking temperature is 140-200 DEG C, and the baking time is 90-160 s. According to the method, a treating agent is used for finishing a fatty polyamide fiber / polyurethane fiber fabric. The finished fabric can absorb water, is moisture permeable and can be fast dried. The fabric touches soft, fluffy and smooth and is good in draping and washing resistance.

Description

technical field [0001] The invention relates to the field of finishing of knitted fabrics, in particular to a method for improving the moisture absorption and perspiration performance of nylon / ammonia knitted fabrics. Background technique [0002] The most prominent advantage of nylon is that its wear resistance is higher than that of all other fibers, 10 times higher than cotton and 20 times higher than wool. Adding some nylon fibers to blended fabrics can greatly improve its wear resistance; When stretched to 3-6%, the elastic recovery rate can reach 100%; it can withstand tens of thousands of times of bending without breaking. [0003] Generally speaking, the strength of nylon fiber is 1-2 times higher than that of cotton, 4-5 times higher than that of wool, and 3 times that of viscose fiber. However, the heat resistance and light resistance of nylon fiber are poor, and the retention is not good, and the clothes made of it are not as crisp as polyester. In addition, bot...
