Wool is an important raw material in the textile industry, which has advantages such as good elasticity, strong moisture absorption, and good warmth retention. However, due to its high price, it is not widely used in the production of non-woven fabrics. Non woven fabrics produced with good wool are limited to some advanced industrial fabrics such as needle punched blankets and advanced needle punched felt. Generally, short and coarse wool from wool processing is used to produce carpet pads, needle punched sandwich layers, thermal insulation materials, and other products through methods such as needle punching and sewing. This type of wool has varying lengths, high impurities, poor spinnability, and difficult processing. The product can be chemically treated to improve quality. Wool textiles are known for their luxurious, elegant, and comfortable natural style, especially cashmere, which is known as "soft gold"

Chemical properties

The main component of wool is keratin, which is composed of various α- Composed of amino acid residues, the latter can be linked into helical long chain molecules containing carboxyl, amino, and hydroxyl groups, forming salt and hydrogen bonds between molecules. Long chains are interconnected by disulfide bonds formed by cysteine. The above chemical structure determines the characteristics of wool. When the long chains of macromolecules in hair fibers are stretched by external forces α Spiral transition to β Type extension type, after external force is relieved, it returns to α Type, its appearance is characterized by excellent elongation, deformation, and resilience of wool. The strong moisture absorption ability of wool is related to some functional groups on the side chains. Wool is more acid resistant than alkali resistant because alkali easily decomposes the disulfide group in wool cystine, causing damage to the hair quality. Oxidants can also destroy disulfide groups and damage wool
