In daily life, we often hear the words artificial cotton, artificial wool and rayon, and these are made of viscose or Made of viscose fiber. 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 use it on clothing tags or wash When you see the percentage of viscose fiber contained in the label (also known as the care label or care label), it indicates the content of viscose fiber in the garment.
Viscose fiber is woven because of its good hygroscopicity, easy dyeing, low static electricity and good spinnability. , clothing and other fields are widely used.
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-type short fiber can be made into muslin, 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 is similar to cotton, so it is more resistant to alkali than 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 staple fiberViscose staple fiber can be spun purely or blended with other textile fibers. Fabrics containing viscose fiber are soft, It is smooth, has good breathability and is comfortable to wear. It has bright color and good color fastness after dyeing. It is suitable for making underwear, outerwear and various decorative items.
Viscose filament, the filament fabric is light and thin,except In addition to being used as clothing material, it can also be used to weave quilt tops 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.
Rich and strong fiber, rich and strong fiber is an improved variety of viscose fiber.Pure spinning can Made of fine cloth, silk, etc., blended with cotton, polyester, etc. to produce various garments. It has good alkali resistance, and the woven fabric is stiff and will not shrink or deform after washing. It is relatively durable.
Viscose silk, viscose silk can be used for clothing, quilt covers, bedding and decorations, and Interwoven with cotton yarn, it can be made into feather yarn and thread-woven quilt tops; 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, which has a high The strength and wet modulus, good crimping performance, and fiber properties are close to high-quality long-staple cotton and wool. It can replace part of long-staple cotton for spinning high-count yarn, and replace part of wool for fine and coarse wool spinning.
Strong viscose fiber has high strength, good resistance to multiple deformations, andcan Used as tire cord, conveyor belts, V-belts, ropes 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 fiberhas many uses, such as with polyacrylonitrile or polyvinyl alcohol The composite viscose fiber has a wooly feel and bulkiness and is suitable for making suits, blankets and decorative fabrics.
2. “Straw silk” (i.e. flat wire) and hollow viscose with flat shape and rough feel The fiber has a small specific gravity, large covering capacity and bulking properties. It is suitable for knitting millinery, handbags and various decorative appliances.
3. Viscose fiber grafted with acrylic acid has high ion exchange capacity and can be usedfrom Precious metals such as gold, silver, and mercury are recovered from the waste liquid, and viscose fibers containing various flame retardants can be used in high-temperature and fire-proof industrial sectors.
4. Viscose fiber can also be made into hemostatic fiber after treatment, and hollow viscose fiber has dialysis effect. Used as an artificial kidney, barium-containing viscose filaments are suitable for medical sutures.
In addition, carbon fiber and graphite fiber made by treating viscose fiber have high strength and high Modulus, composite materials made with epoxy resin can be used as ablation materials for space technology; ceramic fibers made from raw fibers blended with viscose and sodium silicate are used as reinforcing materials for high-temperature resistant phenolic resins , can be used for liquid rocket engines, jet engine nozzles and heat shields of space re-entry devices.
The above is the editor’s introduction to viscose and fiber in clothing fabrics, as well as common related fabrics in daily life. Later, the editor will continue to introduce to you about clothing fabrics. Knowledge, if you don’t understand something or want to know something, you can leave a message to the editor.
