Reasons why silk cannot be soaped

1. Because tap water contains calcium and magnesium rods, it will become calcium soap or magnesium soap when it touches soap.

2. In addition, the silk has a positive charge and the soap has a negative charge. The two are easy to combine. The precipitation is attached to the silk surface, and gray-white spots will appear. Therefore, the silk is best rinsed with water or washed with washing powder.

Secondly, when the real silk garments are washed, strong scrubbing will cause the silk fibers to be scratched or "displaced" under the action of magic, stretching and twisting forces, which will cause the clothing to deform and lose its original flatness. quite, shorten the service life.

In addition, if silk clothing is not washed for a long time, the salt in sweat can cause yellow spots on the surface of light-colored silk clothing. Silk garments must be rinsed after washing.
