The Choice Of Pajamas

Hand visual method:
1. By visual inspection, pure silk is soft, light and soft, and has a drooping feeling. And the chemical fiber fabric luster is not soft, bright and dazzling.
2. Silk fibers are slender and long, cotton fibers are short, and wool is curly. The chemical fiber has good uniformity.
3. Feel: Silk feels soft, smooth and comfortable close to the skin. There will be wrinkles when placed, so there is a saying of "no wrinkle and no silk".
Combustion method:
1. When the silk is burning, it has the smell of burning feathers, which is difficult to continue burning and will self-extinguish. Ash is brittle, brittle, fluffy and black.
2. Rayon (viscose fiber) burns with a chemical smell. It burns very fast. The ash is free of ash except for no light, and there is a small amount of gray black ash.
3. Cotton fiber and polyester have a very weak sweetness when burning, do not directly continue to burn or continue to burn slowly, the ashes are hard round and beaded.
4. Both cotton and hemp smelled of burning paper, and the ash was soft and dark gray.
5. Wool burns like silk. The difference can be seen by eye.
