A kind of preparation method of air-permeable and moisture-conducting fabric

Abstract

The invention discloses a preparation method of breathable and moisture transferring fabric. The preparation method specifically comprises the following steps: S1, ensuring that amino acid 1 and phthalic anhydride 2 are subjected to amino protection reaction, so as to obtain protected amino acid with a structure as shown in a formula 3; S2, feeding terephthalic acid 4, the protected amino acid 3,glycol 5 and catalyst aluminum acetate into a stainless steel reaction kettle, and performing esterification, so as to obtain a low polymer 7; S3, performing secondary temperature rise after esterification pre-condensation polymerization in the step S2, and continuing condensation reaction, so as to obtain a high polymer 8; S4, putting the high polymer 8 into an acid solution, and performing deprotection reaction, namely removing protecting groups, so as to obtain modified terylene polyester 9; S5, feeding the modified terylene polyester 9, a dispersant, a defoamer and a softening agent into ascrew extruder, performing fused extruding, and then performing melt filtering, liquid phase viscosity increasing, spinneret orifice extruding to form trickles, lateral blowing air cooling, thread line fatliquoring, winding to form terylene high-strength filaments, dyeing and finishing and spinning, so as to obtain the breathable and moisture transferring fabric.

Description

technical field [0001] The invention belongs to the technical field of fabrics, and in particular relates to a preparation method of breathable and moisture-conducting fabrics. Background technique [0002] With the improvement of living standards and the development of science and technology, consumers have higher and higher requirements for clothing. They require comfortable clothing, bright colors and a sense of returning to nature. Natural fiber itself has many advantages, such as strong hygroscopicity of cotton fiber, easy dyeing, comfortable wearing, good alkali resistance, acid resistance and heat resistance, etc., but at the same time, it also has disadvantages. Because cotton fiber contains more hydrophilic groups, it has excellent water absorption capacity. , the water retention capacity is strong, which makes the human body feel uncomfortable, especially when the human body sweats a lot, the cotton fiber will swell after absorbing water, the air permeability will ...

AI Technical Summary

Problems solved by technology

However, since polyester is a hydrophobic fiber, there is a lack of hydrophilic groups in the macromolecules, the molecular chain structure is tight, and the degree of crystallinity and orientation is high, resulting in poor hygroscopicity of polyester, easy to generate static electricity, easy to stain and difficult to dye.
