How to choose pajamas

Hand feeling visual inspection method
1. Visual inspection method: silk has a soft luster, is light and soft, and has a drapey feel. The luster of chemical fiber fabrics is not soft, but bright and dazzling.
2. Silk fibers are slender and long, cotton fibers are short, and wool is curly. Chemical fibers have good uniformity.
3. Hand feeling method: silk feels soft, smooth and comfortable when close to the skin. There will be wrinkles when placed, so there is a saying that "no wrinkles, no silk".
Burning method
1. Silk has a burning feather smell when burning, is difficult to continue burning, and will extinguish itself. The ashes are fragile, brittle, fluffy, and black.
2. When rayon (viscose fiber) burns, it has a burning paper mixed with chemical smell. It continues to burn very quickly. The ashes are all ash-free except for those without light, and there is a small amount of gray-black ash in between.
3. Cotton and polyester have a very weak sweet smell when burning, do not continue to burn directly or continue to burn slowly, and the ashes are hard and round, in the shape of beads.
4. Both cotton and linen smell like burning paper, and the ashes are soft and dark grey.
5. Wool burns similarly to silk. You can tell the difference by visual inspection.
