1, ordinary nylon yarn: stockings made of ordinary nylon yarn belong to early products, and their biggest defects are poor elasticity and low transparency.
2, crystal silk: this material greatly improves the transparency, so that the color of stockings is no longer dim, but the shortcomings of poor elasticity have not been improved, and the feel is rough.
3. Core-spun yarn: it has high transparency and excellent elasticity, overcomes the defects of nylon yarn and crystal yarn, and feels delicate and smooth, belonging to mainstream products.
4. Velvet: Compared with core-spun yarn, velvet has slightly lower transparency, but much higher elasticity, which not only makes it feel better, but also increases warmth.
5. Combed cotton: In the process of cotton fiber processing, the fiber is combed with a combing machine, and almost all kinds of impurities in the fiber are removed. The fabric spun from this cotton will feel better.
6. Lycra: a fiber variety introduced by DuPont. It can be stretched easily, and it can cling to the surface of human body after recovery, with little binding force on human body. The stockings containing Lycra show better elasticity, color and air permeability.
Extended data:
Silk stockings are transparent in color and good in elasticity, and are loved by many women. People used to give it a nice name-glass silk stockings!
At the beginning of the 20th century, people mainly knitted with natural materials such as cotton, wool and silk. Because cotton and wool are opaque and silk is transparent, women's stockings are often made of silk.
Silk stockings are beautiful, but they also have many shortcomings. First, silk is not wear-resistant, and socks are easily worn out; Second, the elasticity of silk is not good enough, and the comfort when wearing it is poor; Third, the high cost of silk production makes silk stockings a luxury that only a few rich people can enjoy. It was not until nylon was invented that stockings entered the lives of ordinary people.
The scientific name of nylon is polyamide fiber, which is also called nylon in China. Polyamide is a polymer with amide group (-CONH-). It is the first synthetic fiber invented by human beings, which opens a new chapter in the synthesis and use of organic polymers.
Nylon (polyamide) fiber can be drawn into very thin and long filaments, which has high transparency, firmness, elasticity and wear resistance, and is especially suitable for textile. Because the raw materials for producing polyamide fiber come from kerosene, air and water, the cost is low, so polyamide fiber quickly replaced silk and became the main material for knitting stockings.
