Lyocell fiber (that is, soluble fiber) was called green fiber in 2 1 century. It is a regenerated cellulose fiber which is wet-spun with N- methylmorpholine -N- oxidation (NMMO) as solvent. Waste can be naturally degraded, and 99.5% of amine oxide solvent can be recycled in the production process. "Very low toxicity, no environmental pollution".
Lyocell fiber has excellent dry and wet strength, the dry strength is close to polyester fiber, and the wet strength is slightly decreased, which is about 85% of the dry strength, so Lyocell fiber has strong mechanical and chemical treatment resistance. At the same time, Lyocell fiber has the advantages of low energy consumption and no pollution in the production process, which is incomparable to conventional viscose fiber and is a real green fiber.
ㄌㄟㄧㄥˊ (Lei Rayon /ㄌˊㄥㄥㄥㄥㄥㄥㄥㄥㄥㄥㄥㄥ) It is made of natural plant cellulose, so it belongs to regenerated fiber. Good water absorption, easy dyeing, easy washing, acid and alkali resistance.
Textiles made of rayon can be used to imitate silk, wool, cotton cloth and flax. Easy to dye; The texture is soft, smooth, cool and good in absorption. But it is not insulated. Used in high temperature and high humidity environment. The disadvantage is that it is not durable (especially when wet), which is also the reason for the entanglement of high humidity coefficient. Clothes should be dry-cleaned or cold-washed, not twisted at high temperature.
Extended data:
Regenerated cellulose fiber is made of cotton linter, wood, bamboo, bagasse, reed and other natural cellulose by chemical treatment and mechanical processing.
Regenerated cellulose fibers include viscose fiber, modal fiber, lyocell fiber, hemp stalk core viscose fiber, bamboo (pulp) fiber, cellulose acetate fiber and so on.
1. Viscose fiber, the floorboard of regenerated cellulose fiber, also called ice silk and silk cotton, is a main variety of man-made fiber. The traditional viscose viscose fiber is made of natural cellulose, which is alkalized and then reacts with carbon disulfide to produce cellulose xanthate. The viscous solution obtained by dissolving in dilute alkali liquor is called viscose, which is made into viscose fiber through wet spinning and a series of treatment procedures.
2. Lyocell fiber is a new generation of regenerated cellulose fiber obtained by dissolving wood pulp in NMMO solvent system without chemical reaction and adopting dry spray wet process. Akzo Nobel Company of Germany obtained the patent in 1978, and was officially named by the International Commission for Artificial Fibers and Synthetic Fibers in 1989.
Tencel is the registered trademark name of lyocell fiber produced by Austrian Blue Crystal Company. A brand-new fiber produced from wood pulp by solvent spinning. It has the comfort of cotton, the strength of polyester, the luxurious aesthetic feeling of wool fabric, the unique touch and soft drape of silk, and it is extremely tough whether it is wet or dry.
4. Modal is a patented product of Austrian Blue Crystal Company, which is a kind of regenerated cellulose fiber with high wet modulus. The raw material of this fiber is European beech, which is made into wood pulp and then processed into fiber through special spinning process. Fiber production technology and its environmental protection. Its wet strength is much higher than that of ordinary viscose, and its luster, softness, hygroscopicity and dyeability are better than those of pure cotton products.
