rayon can't be called leisel, but leisel can be called Rayon, which is one of them.

Lyocell fiber (i.e. soluble fiber) is known as the green fiber in the 21st century. It is a regenerated cellulose fiber which is wet-spun with N- methylmorpholine -N- oxidation (NMMO) as the solvent. Waste can be naturally degraded, and 99.5% of amine oxide solvent in the production process can be recycled. "The toxicity is extremely low and it does not pollute the environment".

Lyocell fiber has excellent dry and wet strength, the dry strength is close to that of polyester fiber, and the wet strength decreases slightly, about 85% of the dry strength, which makes Lyocell fiber have strong resistance to mechanical and chemical treatment. At the same time, the advantages of low energy consumption and pollution-free in the production process of Lyocell fiber are incomparable to those of conventional viscose fiber, and it is a real green fiber.

léi yíng/ㄌㄟˊ ㄧㄥˊ), English Rayon or Viscose, also translated as rayon, the Chinese translation is from Lei Zu, who invented sericulture in China legend. It's an artificial fiber. It is made of natural plant cellulose, so it belongs to regenerated fiber. Good water absorption, easy dyeing, washing, acid and alkali resistance.

The textiles made of rayon can be used to imitate silk, wool, cotton cloth and linen. Easy to dye; Soft texture, smooth, cool, good absorption. But not insulated. Used in high temperature and high humidity environment. The disadvantage is that it is not durable (especially when wet), which is why the high humidity coefficient is entangled. Clothes are suitable for dry cleaning or cold water washing, and should not be twisted or ironed at high temperature.

Extended information:

Regenerated cellulose fiber is made of cotton linter, wood, bamboo, bagasse, reed and other natural cellulose through chemical treatment and mechanical processing.

regenerated cellulose fibers include Viscose fiber, Modal fiber, Lyocell fiber, hemp stalk core viscose fiber, bamboo (pulp) fiber and cellulose acetate fiber.

1. Viscose, the general name of regenerated cellulose fiber, also called ice silk and silk cotton, is a major variety of man-made fiber. The traditional viscose viscose fiber is made from natural cellulose by alkalization, and then reacts with carbon disulfide to form cellulose xanthate. The viscous solution obtained by dissolving in dilute alkali liquor is called viscose, and the viscose fiber is made after 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 using dry spraying wet process. Akzo Nobel Company of Germany obtained a patent in 1978, and was officially named by the International Commission on Man-made Fibers and Synthetic Fibers in 1989.

3.Tencel is the registered trademark name of Lyocell fiber produced by Austrian Lanjing Company. A brand-new fiber produced from wood pulp by solvent spinning. It has the comfortableness of cotton, the strength of polyester, the luxurious aesthetic feeling of wool fabric and the unique touch and softness of silk, and it is extremely tough in both dry and wet conditions.

4.Modal is a patented product of Austrian Lanjing Company, which is a kind of regenerated cellulose fiber with high wet modulus. The raw material of this fiber is European beech wood, which is first made into wood pulp and then processed into fiber through a special spinning process. Production process of fiber 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.
