According to the process, the common varieties of silk fabrics can be divided into several categories, such as crepe de chine, crepe de chine, georgette, double-Qiao, heavy-Qiao, three-treasure satin, crepe satin plain, elastic crepe satin, warp knitting and so on. For example, satin has a smooth and bright appearance, brocade has a gorgeous jacquard surface, and twill has obvious twill. Because the processing technology is different. In general, crepe de chine fabrics have good wrinkle resistance and bright color after high temperature setting. Heavy crepe is slightly thicker, the fabric has good drape and stronger wrinkle resistance; Sambo satin is more common and is often used to make cheongsam. Satin is clear in texture and antique. Crepe satin plain satin is bright and noble, and feels smooth, but its shrinkage rate is large, and its luster will decrease after entering water; Elasticity crepe satin contains 5% to 10% spandex besides mulberry silk, which has good elasticity and small shrinkage. All-silk fabric has pearl luster and a slight scratch to the touch. Chemical fiber fabrics are bright and dazzling, and feel stiff.

Although silk-like fabric feels soft, its silk surface is dark and has no pearl luster. Secondly, the shrinkage of silk fabrics, especially silk crepe de chine, is between 8% and 10%, and its wrinkle resistance is slightly worse than that of chemical fiber, so you must be careful when you meet silk that claims to be completely non-shrinking and wrinkle-free. Three-filament fiber is slender and long, cotton fiber is short, wool is curly and chemical fiber is neat. Fourth, when silk burns, it smells like burnt feathers, which are gray, crisp, fluffy and black; When rayon (such as viscose) burns, there is burning paper mixed with chemical smell; Polyester has a faint sweetness when burning, and the ash is hard and round; Cotton and linen all smell of burning paper, and there are dark gray ashes.
