Crease-resistant and shrink-resistant finishing agent for hemp fabric

Abstract

A crease-resistant and shrink-resistant finishing agent for a hemp fabric comprises components in parts by mass as follows: 15-25 parts of silk fibroin, 5-10 parts of polyurethane, 1-3 parts of diepoxy triglycol glycidyl ether, 1-5 parts of glyoxal and 2-4 parts of citric acid, preferably, 20 parts of silk fibroin, 8 parts of polyurethane, 2 parts of diepoxy triglycol glycidyl ether, 3 parts of glyoxal and 3 parts of citric acid, wherein the mass ratio of silk fibroin to fatty alcohol-polyoxyethylene ether is 5:2. The provided crease-resistant and shrink-resistant finishing agent adopts silk fibroin as a main finishing agent ingredient, is safe and non-toxic, has excellent biocompatibility, and is particularly suitable for crease-resistant and shrink-resistant finishing of the hemp fabric, so that the crease resistance of the fabric is improved, the hemp fabric has a better washable characteristic, and the hand feeling, the breathability and the moisture absorption of the hemp fabric are kept.

Description

technical field [0001] The invention belongs to the technical field of textiles, and in particular relates to an anti-wrinkle and anti-shrink finishing agent for linen fabrics. Background technique [0002] Hemp is the cortical fiber of plants. Its function is to approximate human skin, to protect the human body, to regulate temperature and other natural properties. Compared with other clothing materials, linen can reduce the sweating of the human body. It absorbs water several times faster than silk, rayon, and even cotton. It forms capillary phenomenon when it contacts the skin, which is an extension of the skin. This natural breathability, moisture absorption, refreshing and moisture-wicking properties of hemp make it a freely breathing textile. However, linen fabrics are easy to wrinkle. Currently, the anti-wrinkle and anti-shrinkage technology for cotton fabrics is relatively mature, but compared with cotton fibers, hemp fibers have higher crystallinity and orientation...

AI Technical Summary

Problems solved by technology

However, linen fabrics are easy to wrinkle. Currently, the anti-wrinkle and anti-shrinkage technology for cotton fabrics is relatively mature, but compared with cotton fibers, hemp fibers have higher crystallinity and orientation. It is not suitable for linen fabrics. Most traditional anti-wrinkle and anti-shrinkage finishing agents such as 2D resin have the problem of formaldehyde release and are gradually eliminated. Biological finishing has become a new type of finishing technology that people pay attention to.
