1. Raw materials:
The yarn components of good-quality socks are mainly made of cotton, combed cotton, cotton wool, wool, and rabbit hair. These are all high-quality raw materials for knitting socks, which are cool and breathable in summer. Warm your feet in winter.
A: Use a needle to pick up a piece of yarn inside the sock. Pay attention to the yarn that has no elasticity. Use a lighter to burn it. The smell will be a pungent plastic smell and the burning mass will look like hair. Large chemical fiber socks. "When burning, there are no lumps, and there is dust falling, and the smell is like burning paper, that is, they are pure cotton socks."
B: In addition, if cotton socks are worn for a long time, the surface layer will fall off layer by layer. Remember, it is layer by layer. The better the cotton and the better the sports socks, the more obvious the effect will be. Even though these socks are old and falling off, they are indeed good socks.
2. Socks trademark:
Remember, the color of the paper card on the back of the trademark of imitation foreign trade chemical fiber socks is gray. Because this kind of trademark is extremely cheap, the manufacturer will not use the expensive trademark to package the socks. Moreover, the workmanship of the trademark is rough and the trademark is soft. It is thin and the printed pattern in English is also very simple. The exported foreign trade trademark paper cards are very thick and the back of the paper cards is pure white.
