1. The silk is covered with 3 layers, namely silk, inner sleeve and quilt cover. The silk + inner sleeve is the so-called core, which cannot be washed (except for the washable silk cold), and the quilt cover can be removed and washed. Therefore, the silk is best protected with a quilt cover. 2. If the core is accidentally contaminated with stains, it can be partially wiped with a neutral detergent (such as washing spirit for washing fruits and vegetables). Silk fiber is acid and alkali resistant. Avoid using too much alkaline detergent and soap. Wash to prevent damage to the fibers. The soap also combines with calcium and magnesium ions in the water to form soap scum, which is deposited on the silk fibers to make the silky yellow and coarse. It is better to wash by hand, and the washing temperature is below 30 °C. If it needs to be soaked in water, the time should not exceed 5 minutes. Do not wring after washing to prevent the silkworm from shifting and the silk surface. Since silk protein molecules are yellowed and fragile in daylight, they can only be dried. Can not be handled by yourself can be sent to the dry cleaners.
