Characteristics And Identification Methods of Viscose, Modal and Lyocell

Viscose fiber features:

Alkali cellulose is formed from natural cellulose by alkalization, and then react with carbon disulfide to produce cellulose xanthate. The viscous solution obtained by dissolving in dilute lye is called viscose. Viscose is formed into viscose fiber after wet spinning and a series of processing processes. Viscose fiber is the first regenerated cellulose fiber produced and processed.

The production process will release carbon disulfide, hydrogen sulfide, physiological harmless, biodegradable.

Viscose staple fiber has good moisture absorption and meets the physiological requirements of human skin. The fabric is soft, smooth, good air permeability, not easy to get static electricity, anti-ultraviolet light, comfortable to wear, easy to dye, bright color after dyeing, good color fastness, and good spinnability. Low wet modulus, high shrinkage rate and easy deformation, hard feel after launching, poor elasticity and wear resistance.

Modal's characteristics:

It is a kind of high wet modulus regenerated cellulose fiber, which is made from wood pulp made from shrub in Europe by special spinning process.

The production process is pollution-free, physiologically harmless and biodegradable.

Model feel soft, smooth, beautiful color, color fastness, fabric feel particularly smooth, bright and shiny cloth, drapiness are better than the existing cotton, polyester, viscose fiber, with the strength and toughness of synthetic fiber, silk-like luster and feel, its fabric has wrinkle resistance and ironing, water absorption and air permeability is good, but its fabric is poor crisp.

Characteristics of Lyocell fibers:

The pulp formed from natural plant fiber was prepared by organic solvent spinning. The advanced process makes the solvent recovery rate up to 99.7%, energy saving, environmental protection, and sustainable development.

The production process has no chemical reaction, the solvent used is non-toxic, the waste is biodegradable, and the production process is simple, which can save oil resources and meet the requirements of environmental protection.

Lyocell fiber has a variety of excellent properties of natural fiber and synthetic fiber, natural luster, smooth feel, high strength, basically no shrinkage, and good moisture permeability, air permeability, soft, comfortable, smooth and cool, good drdrability, durable.

Lyocell covers all areas of textile, whether it is cotton, wool, silk, linen type products, or knitting or weaving fields can produce high quality products.
