Silk is a kind of natural protein fiber closest to the composition of human skin. It's very delicate. You must pay attention to correct cleaning and maintenance. Wash with cold water, pay attention to hand washing, do not wring dry, and do not use washing powder and soap. It should be washed with a special detergent for silk. It should not be soaked or twisted dry to avoid damaging the surface of silk. It is not easy to wrinkle when hanging in a cool place with water or lying flat.
