How are socks made? Please, great gods.

At first, socks were made of natural materials such as flax, cotton, silk and wool. 19 12 years, the appearance of artificial stockings replaced the more expensive natural fabric socks, which made more ordinary people enjoy the happiness of fashion. 1928, DuPont exhibited the first pair of nylon stockings. Today, DuPont's man-made fibers still have high authority. Silk stockings are made of nylon, spun into yarn and woven with high-density and fine special machines. With the continuous upgrading of nylon yarn, the appearance of other man-made or natural fiber processing yarns, and the technical improvement of hosiery machine in recent years, the styles and raw materials of stockings have become more diverse. It can be seen that although socks are small, they are the crystallization of human aesthetics and the development of synthetic fiber technology in textile machinery. At present, the stockings sold in the market are roughly divided into three categories according to the materials: 1 and nylon stockings, and nylon stockings are the most common and common stockings. Woven with ordinary nylon or crystal yarn, it has high strength, good wear resistance and strong elasticity, but poor transparency. In the early days when stockings appeared, they almost occupied the whole market. Now, under the impact of new materials, the market share has shrunk, but because of its low price, it is favored by quite a few people. 2. Bract core-spun yarn: refers to spandex bract core-spun yarn formed by winding nylon yarn on spandex yarn. When weaving, it is made of bract core yarn and common filament yarn or nylon plus elastic yarn, which has high elasticity, durability and high transparency. Core-spun yarn is a popular product in recent years, which has both the excellent elasticity of velvet and the softness and wear resistance of nylon, and its price is moderate. In addition, it also has a certain health care function. Moderate pressure can massage the skin, relieve fatigue and prevent vein bending. 3. Velvet: also known as full-bud core-spun yarn. It means that stockings are all woven with unidirectional or bidirectional sheath yarns. The knitted socks have high elasticity and softness, delicate feel, high transparency, elegant vision, durability and high wear resistance. Six-gear design of stockings: ordinary gear: suitable for standard figure. Single shift: suitable for overweight people. Double gear: suitable for obesity and pregnant women.
