Method for providing anti-felting function for wool fabric

Abstract

The invention relates to a method for providing an anti-felting function for a wool fabric. The method utilizes tris(2-carboxyethyl)phosphine (TCEP) to pre-treat a wool fabric so that disulfide bonds in wool fiber keratin are broken to form mercapto groups with high activity. 2-propenoic acid-(2-hydroxy-1,3-propanediyl)bis[oxy(2-hydroxy-3,1-propanediyl)]ester (GDA) and the wool fabric pre-treated by TCEP undergo a click chemical reaction, in other word, C-C double bonds and the mercapto groups undergo a reaction so that a molecular chain rich in hydroxyl is introduced into wool protein molecules by a medical bonding method. The treated product has an anti-felting function, realizes a certain degree of machine washing, has good size stability and has a certain durability by chemical treatment. The method has substantial effects, belongs to a chlorine-free treatment method and is safe and environmentally friendly.

Description

technical field [0001] The invention belongs to the field of modification of wool fabrics, in particular to a method for making wool fabrics have an anti-felting function. Background technique [0002] Wool has many excellent properties, such as good elasticity, strong moisture absorption, good warmth retention, and soft luster. Wool fabric is deeply loved by consumers for its noble style and superior wearing performance. However, unfinished wool fabrics will experience shrinkage after being continuously squeezed and rubbed during washing, which will cause changes in the appearance of the fabric, such as shrinkage of the fabric size, hairiness of the woolen surface, and chaotic weave, which can seriously affect the appearance and wearability of the fabric. , to a certain extent, limits the application field of wool, so wool textiles must be anti-felted through post-finishing methods, so that wool fabrics not only maintain the original high-grade texture, but also make break...

AI Technical Summary

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.

[0006] 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
