What is the fabric of viscose fiber? We often encounter such a situation when we buy Clothes
, that is, when we consult the fabric of clothes, we will hear the word viscous fiber from the mouth of the salesperson. So, what kind of fabric is viscose fiber? What are the characteristics of textiles made of this fabric? If you want to know more about the problem of what kind of fabric is viscose, please check the following interpretation.
In general, many of the smoother, cooler, breathable, and antistatic properties we see are very good for dyeing. They are made from viscose fabrics. In fact, the so-called viscose fiber, also known as viscose fiber, viscose fiber is divided into viscose filament and viscose staple fiber, also known as rayon, ice silk. It is further divided into viscose filaments and viscose staple fibers.
After 2000, a new high-grade variety named Tencel and bamboo fiber appeared in viscose fiber. Viscose fibers are cellulose fibers produced from cotton or other natural fibers. Among the 12 main textile fibers, the moisture content of viscose fiber is most in line with the physiological requirements of human skin. It has smooth, cool, breathable, antistatic, and beautiful dyeing characteristics. In the past few years, viscose fiber has emerged a new high-grade variety called Tencel and bamboo fiber.
However, no matter how it changes, viscose fiber is still produced from cotton or other natural fibers as raw material cellulose fibers. It should be noted that viscose fiber is a very historic old fiber variety. As early as the end of the 19th century, scientists first used cotton as a raw material to make a sodium cellulose naxite solution. The viscosity of this solution was very large, so the glue was named viscose and the glue reacted with acid. After that, the cellulose was again separated. People later used this reaction to make cellulose fibers based on this principle phenomenon.
Later, in order to achieve industrial production, scientists invented a coagulation product consisting of dilute sulfuric acid and sulphate, thus realizing the current production of large quantities of viscose fiber, and there is a lot of what we have seen so far. A beautiful, cool clothing made of viscose fiber. Seeing here, everyone should have some understanding of what viscose fabrics are.
So what kind of fabric is viscose? In general, viscose fiber fabrics have the essence of cotton fabrics, and at the same time they also have good silk quality. They are an authentic ecological fiber fabric. Viscose fibers are derived from natural and better than natural, because viscose fibers are made from the relatively short wool of cotton as a raw material, so viscose fibers are inherently more pure than cotton fibers. For example, viscose fiber has a cellulose content of more than 99.5%, while cotton fiber only oscillates at about 95% to 97%.
The main varieties of viscose fiber:
1, ordinary viscose fiber
(1) Viscose staple fiber cut length 35 to 40mm, denier 1.1 to 2.8dtex (1.0 to 2.5 denier) and cotton blends can be fine cloth, valine, gabardine and so on.
(2) Viscose-type short fibers, cutting length 51 ~ 76mm, denier 3.3 ~ 6.6dtex (3.0 ~ 6.0 denier), can be pure spinning, can also be blended with wool, can be tweed, coat it and so on.
2, rich fiber
(1) is an improved type of viscose fiber.
(2) pure spinning can be fine cloth, poplin and so on.
(3) Blended with cotton, polyester, etc. to produce a variety of garments.
(4) Alkali resistance is good, the woven fabric is stiff and does not shrink or deform after washing. It is more wearable and durable.
3, viscose silk
(1) Can do clothing, quilt cover, bedding and decorations.
(2) The viscose rayon is interlaced with the cotton yarn.
(3) Viscose silk and silk silk intertwined, can do georgette, brocade and so on.
(4) The viscose thread is interwoven with polyester and nylon filaments, which can be used as crystal satin, satin and so on.
4, viscose strong wire
(1) The strength is twice as high as ordinary viscose.
(2) Twisted into cord fabrics for automobile, tractor and carriage tires.
5, high curl high modulus viscose fiber
High-crimp, high-moisture-content viscose fiber (expressed in HR) is a new generation of viscose fiber that has high strength and wet modulus, moderate elongation and good curling properties, plus viscose fiber itself Excellent moisture absorption, air permeability, no static electricity, good dyeing performance, fineness and length can be flexibly adjusted, etc. It is a kind of textile fiber raw material with relatively comprehensive performance. It can be used purely according to different needs. The hygroscopic properties and the dyeing properties of the viscose fiber are closely related to the fact that the fiber itself contains a large amount of hydroxyl groups (â€”OH). The hydroxyl group (â€”OH) group absorbs a large number of water molecules or other molecules, and the better the hygroscopicity is, the better the fiber dyeability is. Viscose fibers undergo many physical and chemical reactions during the manufacturing process, resulting in the cleavage of large cellulosic molecules, shortening their macromolecules, creating large molecular gaps, and disorganizing the arrangement of hydroxyl groups (-OH) in the molecule. It can be polar or better in these areas than cotton. Therefore, viscose fiber dyeing is better than cotton, not only apply more dyes, chromatography, dyeing color is also bright.
On the other hand, cellulose acetate fibers (including diacetate fibers and triacetate fibers) of cellulose regenerated fibers have significantly inferior dyeing properties to viscose fibers. This is due to the fact that most hydroxyl groups (-OH) in the acetate fiber molecules are acetylated to form hydrophobic groups. Therefore, viscose fibers and dyes that cotton can use are not necessarily available. Visible in the cellulose fiber, viscose fiber dyeing is also the best, but also easy to dye, and printing and dyeing costs are lower. Viscose fibers also have deficiencies in printing and dyeing. For example, they can be widely used in reactive dyes like cellulose fibers such as cotton. Reactive dyes can replace some harmful chemical dyes, but it has more colored wastewater in the process of printing and dyeing. In addition, viscose fibers are inferior to certain synthetic fibers in terms of their color fastness and lightfastness. Although this is related to dye performance and process, viscose fiber's easy-to-dye, full color, bright color and low cost are still advantages.
It is because of the pure nature of viscose fiber that it can withstand sun exposure, anti-mite, high temperature resistance, is not allergic to chemicals, and has good resistance to meltable solvents and molds. Therefore, in the current major textile fabrics, The performance of the viscose fabric is very comprehensive.
