Problems solved by technology

Although the chlorination anti-shrinking process is quite mature, there are still many disadvantages: for example, it is difficult to ensure the uniformity of the chlorination process, the wool is easy to yellow, the hand feels rough, and the fibers are easily damaged.
In recent years, the protease treatment method has also been widely concerned with the improvement of people's safety awareness, but the biological modification of wool with protease alone is not very effective, because the lipid structure in the scale layer greatly reduces the availability of enzyme molecules. time, so it is difficult to make a difference

Abstract

The invention relates to a method for preparing an antistatic anti-felting wool fabric with good dyeing property. The method comprise the following steps: pre-treating wool fabric with tris(2-carboxyethyl) phosphine (TCEP) to break disulfide bonds in wool fabric keratin to form sulphydryl with higher activity, and then grafting molecular chains containing acrylate in the presence of triethylamine through the thiol-ene click chemical reaction to obtain the wool fabric. The method disclosed by the invention not only has remarkable effect but also is safe and environment-friendly, has no harm to human bodies and environments, and is simple and effective as the groups of the wool are directly used as the active groups.

Description

Technical field [0001] The invention belongs to the field of preparation of functional wool fabrics, and particularly relates to a method for preparing wool fabrics with antistatic, anti-felting and good dyeing properties. Background technique [0002] Wool fabric has excellent drapability and warmth retention, natural and elegant luster, smooth and active hand feel, not easy to stain, and full of elasticity. It has been used as high-end clothing fabrics and occupies an important position in textiles. However, although wool is a natural fiber, because the surface of the wool fiber is attached with a layer of overlapping scales, the surface of the scales is a double-layer structure that completely covers the entire scale cells, and the outside is a highly hydrophobic lipid layer. It is formed by combining 18-methyl arachidic acid and arachidic acid with protein peptide chains through sulfolipid bonds and lipid bonds. It is about 0.9nm thick and has strong chemical stability. Alth...
