Rayon fabrics basically refer to viscose filament and staple fiber fabrics, commonly known as rayon and rayon. In addition, it also includes some fiber-rich fabrics and medium-long fiber fabrics between filaments and short fibers. Therefore, the performance of rayon fabric is mainly determined by the characteristics of viscose fiber.
1. rayon and rayon fabrics are soft to the touch, breathable, comfortable to wear and brightly dyed.
2. Rayon fabric has good hygroscopicity, which is the best in chemical fiber. However, its wet strength is very low, only about 50% of the dry strength, and the shrinkage rate of the fabric is large, so it is best to shrink in advance before cutting.
3. Ordinary viscose fabric has the characteristics of good drape, poor rigidity, poor resilience and poor wrinkle resistance, so its clothing has poor shape retention and is easy to wrinkle.
4. Viscose fiber fabric has good acid and alkali resistance, sunlight resistance and other drug resistance.
Cotton fiber is easy-going and easy to dye into various colors. Moreover, cotton fiber has good air permeability, especially absorbs sweat, and is the main material of most underwear. In addition, the durability of cotton fiber is also recognized, and the sheets, towels and curtain cloth commonly used at home are all its masterpieces! The amount of cotton fiber used to occupy a major position in the rubber industry, but at present it only accounts for about 5% of the total fiber. Cotton fiber has low strength, but good ductility, fatigue resistance and heat resistance, and it is easier to bond with rubber than synthetic fiber.
Computer software engineering is a discipline that studies, builds and maintains effective, practical and high-quality software by engineering methods.
