Viscose filament is called rayon, or rayon for short
Rayon is a silky man-made fiber composed of cellulose, which is an organic compound that constitutes the main component of plants. Because it is a cellulosic fiber, many of its properties are the same as those of other fibers such as cotton and linen. This fiber is tooth-shaped.
Viscose man-made fiber is a medium-heavy fiber with average to good strength and wear resistance. It has hydrophilic properties (moisture regain 11%). This fiber can be dry-cleaned in good condition. It can also be washed with care, will not produce static electricity or pilling, and is not expensive.
The end uses of rayon are in clothing, interior decoration and industrial fields (such as: women’s tops, shirts, underwear, jackets, hanging fabrics, pharmaceuticals, nonwovens, hygiene products, etc.) .
Viscose staple fiber It is called artificial cotton, or rayon for short
Cotton-type viscose short fibers, such as cotton-type viscose short fibers, are chemically spun from natural polymer compounds such as cellulose or protein. Its specifications are similar to cotton fibers. The length is generally 35mm. The fineness is 1.5~2.2dtex. It can be spun purely on cotton spinning machines or blended with cotton or cotton-type synthetic fibers (such as polyester, nylon, etc.).
Artificial cotton is a cotton-type short fiber spun from natural cellulose. Mainly viscose short fiber. It is characterized by good dyeability, high brightness and fastness, comfortable wearing, resistance to dilute alkali, and hygroscopicity close to cotton. The disadvantages are that it is not acid-resistant, has poor resilience and fatigue resistance, and has low wet mechanical strength. It can be spun purely or blended with chemical fibers such as polyester.
Generally speaking, artificial cotton is not only cellulose, but also includes many other chemical fibers, which is another matter.
Cotton and rayon are both cellulose. They have the same composition as starch, but the molecular weight is larger. Rayon is made by dissolving cellulose in a solvent and then spraying it out from a very fine nozzle to form filaments, similar to spider silk. Therefore, it is indistinguishable by burning. It mainly depends on the feel. The artificial cotton should be smoother.
