1. It is best to use soft water when washing, the temperature is 35-40 degrees Celsius for the best results.

2. Alkali has a destructive effect on silk fibers, and neutral detergents or silk wool detergents are suitable. It is not suitable for soap washing. Because tap water contains impurities such as calcium and magnesium, it will turn into calcium soap or magnesium soap when touched by soap. With the positive charge of the ribbon, the two will easily combine and precipitate to adhere to the silk surface, resulting in grayish-white stains. It is recommended to use special detergent for silk wool.

3. Salt is also very destructive to silk, so silk clothing should be changed and washed frequently. The silk clothes you have changed should be washed in time. Otherwise, the dirt on the clothing will affect the original luster and appear "spotted" phenomenon.

4. Do not stir vigorously or twist hard during washing, but rub it gently. Rub and rinse. If silk clothing is rubbed vigorously, it is easy to damage the silk fibers. Under the action of friction, stretching and twisting forces, the light and weft lines of the fibers are prone to "displacement" and thus deforming the clothes.

5. Do not twist the washed silk clothes hard. Just squeeze them gently with your hands and use a clothes rack to dry them flat. Hang them in a cool and ventilated place to dry. Do not expose them to the sun to avoid the fiber brittlement caused by ultraviolet radiation in the sun. Do not expose it to the sun and dry it. Silk fibers contain amino acids, which are very easy to absorb ultraviolet rays in sunlight and cause brittleness. After the silk fabric is washed, it will sometimes turn yellow under sun exposure.

Silk fibers are protein fibers, composed of various amino acids, and can be hydrolyzed in alkaline solutions and lose their fastness. Therefore, do not use alkaline soap when washing. It is best to soak the clothes in warm water first to remove floating ash, so as to soak the dirt and fiber. If there are more sweat stains on the clothes, add a spoonful of salt to the water and soak for 20 minutes to dissolve the protein in the sweat, then soak it in the soapy water and rub it with your hands. And rinse it with clean water. If the clothes have been worn for a long time, sweat stains and oil stains are thicker, and yellow stains have appeared, they need to be washed with citric acid solution.
