Sand-washed silk garments are mostly variegated printed crepe shirts and jackets with pleated satin. Sand-washed silk requires that silk be partially broken to expose fibrils, and the fabric is soft and smooth, shrink-resistant and wrinkle-resistant, and has good drape. There seems to be a mist on the surface of silk, which has a good writing effect, and double-thread sewing has a slight whitening effect. Sand washing treatment requires color retention (brightness and color fastness) to prevent hand feeling from weakening, hair loss and lining sticking.
