wool yarn

Combed cotton wool yarn
Wool blended fabrics, that is, fabrics made of cashmere, polyester, spandex, rabbit hair and other fibers mixed with wool.
1. The surface of wool blended fabrics has sparkles in the sun, and it lacks the softness of pure wool fabrics.
2. Wool blended fabrics are stiff but stiff, and stand out obviously with the increase of polyester content.
3. The wool blend has a brighter luster. Generally speaking, worsted wool-blend fabrics are soft to the touch, while woollens are loose. In addition, its elasticity and stiffness are not as good as pure wool and wool polyester and wool blended fabrics.

viscose wool yarn
The main component of wool is keratin, which is composed of a variety of α-amino acid residues, which can be combined into long-chain molecules in a spiral shape, which contain carboxyl groups, amine groups and hydroxyl groups, forming salt bonds between the molecules. and hydrogen bonds, etc. The long chains are linked by cross-bonds formed by disulfide bonds of cystines. The above chemical structure determines the characteristics of wool. If the long chain of wool fiber macromolecules is stretched by external force, it transitions from α-type helical shape to β-type extension type, and returns to α-type after the external force is removed, then its appearance is excellent in elongation deformation and resilience of wool. The stronger hygroscopic ability of wool is related to some groups on the long chain. Wool is more acid-resistant than alkali-resistant, because alkalis are prone to disulfide groups in wool cystine, which damages the wool. Oxidizing agents can also damage the wool by destroying the disulfide groups.
