　　Raw silk is soft, smooth, and full in hand feel, with excellent tensile strength and elasticity. It has a gentle luster, strong moisture absorption, and is non-irritating to the human body. As a high-end textile material, it can be woven into various types of silk fabrics with different structures, used for clothing, home furnishings, handicrafts, decorations, and more. Raw silk also has a very high specific strength, excellent electrical insulation properties, good thermal insulation, and is flammable but burns slowly. It has important applications in industry, national defense, and medicine, such as in the production of insulating materials, parachutes, and artificial blood vessels.
