In daily life, we often hear the words artificial cotton, artificial wool and rayon, and these are all made of viscose or viscose. When we buy textiles and clothing and see products containing viscose and viscose, it means that these are artificially manufactured.
What are viscose and viscose?
Viscose and viscose are the abbreviations of viscose fiber. When we see the label containing The percentage of viscose fiber indicates the content of viscose fiber in the garment.
Because viscose fiber has good hygroscopicity, is easy to dye, is not prone to static electricity and has good spinnability, it is widely used in textile, clothing and other fields.
Viscose fiber is a chemical fiber variety, the main variety of man-made fiber, and one of the ancient fiber varieties. The main raw material of viscose fiber is chemical pulp, including cotton pulp and wood pulp, which can be spun pure or blended.
For example, viscose cotton short fiber can be made into fine cloth, viscose, gabardine, etc. after being blended with cotton. Viscose wool-type short fiber, which can be made into tweed, coats, etc. after being purely spun or blended with wool.
Viscose fiber has good hygroscopicity, is easy to dye, is not prone to static electricity, and has good spinnability. Its chemical composition is similar to cotton, so it is more resistant to alkali but not acid. , but its alkali and acid resistance is worse than cotton. In addition, the dyeability of viscose fiber is similar to that of cotton, with a full dyeing spectrum and good dyeing performance.
Classification and application of viscose fiber
Viscose short Fiber, viscose short fiber can be spun purely or blended with other textile fibers. Fabrics containing viscose fiber are soft, smooth, have good air permeability, and are comfortable to wear. They have bright colors and good color fastness after dyeing, and are suitable for making underwear. , outerwear and various decorative items.
Viscose filament, filament fabric is light and thin in texture. In addition to being suitable for clothing, it can also be used to weave quilts and decorative fabrics. The disadvantages of this type of viscose fiber are poor fastness, low wet modulus, high shrinkage and easy deformation, poor elasticity and wear resistance.
Fuqiang fiber, Fuqiang fiber is an improved variety of viscose fiber. Purely spun into fine cloth, silk, etc., and blended with cotton, polyester, etc. to produce various clothing. It has good alkali resistance, and the fabric is stiff and will not shrink or deform after washing, making it more durable.
Viscose silk, viscose silk can be used for clothing, quilts, bedding and decorations, interwoven with cotton yarn, It can be made into feather yarn and thread-woven quilt cover; interwoven with silk, it can be made into georgette, brocade, etc.; interwoven with polyester and brocade filaments, it can be made into crystal satin, antique satin, etc. The strength of viscose strong yarn is twice that of ordinary viscose yarn. It is twisted and woven into cord fabric, which is used for automobile, tractor and carriage tires.
High crimp and high wet modulus viscose fiber. This fiber has high strength and wet modulus, good crimp performance, and fiber properties are close to high-quality long-spun cotton and Wool can replace part of the long-staple cotton to spin high-count yarn, and replace part of the wool for fine and coarse wool spinning.
Strong viscose fiber has high strength and good resistance to multiple deformations. It can be used as tire cord, conveyor belt, V-belt, rope and various industrial fabrics, such as Canvas, plastic coated fabrics, etc.
Viscose fiber has more uses after processing, details are as follows:
1. Modified viscose fiber has a variety of uses. For example, viscose fiber compounded with polyacrylonitrile or polyvinyl alcohol has a wooly feel and bulkiness, and is suitable for making suits, blankets and decorative fabrics.
2. “Straw filaments” (i.e. flat filaments) and hollow viscose fibers with a flat shape and rough feel have small specific gravity, large covering capacity and bulking properties, and are suitable for Used in weaving millinery, handbags and various decorative appliances.
3. Viscose fibers grafted with acrylic acid have high ion exchange capabilities and can be used to recover precious metals such as gold, silver, and mercury from waste liquids. They contain various A kind of flame retardant viscose fiber, which can be used in high temperature and fireproof industrial sectors.
4. Viscose fiber can also be made into hemostatic fiber after treatment. Hollow viscose fiber has dialysis effect and can be used as an artificial kidney. Barium-containing viscose filament is suitable Make medical sutures.
In addition, carbon fiber and graphite fiber made from viscose fiber treatment have high strength and high modulus, which are consistent with Epoxy resin etc.Composite materials can be used as ablative materials for space technology; ceramic fibers made from raw fibers blended with viscose and sodium silicate can be used as reinforcing materials for high-temperature resistant phenolic resins and can be used in liquid rocket engines and jet engines. nozzle and space reentry device heat shield.
