1. Combed cotton and curd cotton are all pure cotton. Combed cotton has short fibers and fewer impurities, the fibers are straight and parallel, the yarn is uniform,the surface is smooth. Carded cotton is rough, textured, and not uniform. 2. Polyester polyester
has high strength and wear resistance, not easy to wrinkle, exceeds all fibers, and the shape of the fabric holds is
good. There are no hydrophilic groups in the composition of polyester, so the fibers absorb almost no moisture.
Polyester is second only to polyacrylonitrile fiber and has good light resistance. It also has very good heat resistance,
no mold or rot.
3. Spandex is
synthetic. It has the characteristics of high elongation and high elasticity, has better acid resistance, alkali light
fastness and wear resistance.
4. It is nylon
synthetic. The wear resistance is particularly good, ranking first among common fiber fibers, but
it does not absorb sweat and smelly feet. If it is only used for jacquard, it basically does not affect
the performance of the sock."
