What kind of fabric is viscose? What are the characteristics of clothes made of viscose fiber?
[What kind of fabric is viscose fiber?] We often encounter this situation when buying clothes. That is, when consulting about clothing fabrics, we will hear the word viscose fiber from the salesperson. word. So, what kind of fabric is viscose fiber, and what are the characteristics of fabrics made from this fabric. If you want to have a more detailed understanding of what kind of fabric viscose fiber is, then please read the following explanation carefully.
Generally speaking, many of the clothes we see that are smooth and cool, have both breathability and good antistatic properties, and are very colorful after coloring, are made of viscose fabrics It’s done. In fact, the so-called viscose fiber is also called viscose fiber. Viscose fiber is divided into viscose filament and viscose staple fiber. It can also be called rayon and ice silk. It is further divided into viscose filament and viscose staple fiber. After 2000, a new high-end variety of viscose fiber called Tencel and bamboo fiber appeared. Viscose fiber is a cellulose fiber produced from cotton or other natural fibers. Among the 12 main fabric fibers, the moisture content of viscose fiber meets the physiological requirements of human skin, and it has the characteristics of being perfectly smooth and cool, breathable, antistatic, and colorful. In recent years, a relatively high-end new variety of viscose fiber called Tencel, bamboo fiber, has appeared. But no matter how it changes, viscose fiber is still cellulose fiber produced from cotton or other natural fibers. It should be understood that viscose fiber is an ancient fiber variety with a special history. As early as the end of the 19th century, scientists first made a cellulose sodium xanthate solution using cotton as raw material. The viscosity of this solution was particularly high, so the glue was named viscose, and when this viscose reacted with acid, it Later, cellulose was separated again. People later used this reaction to make cellulose fibers based on this principle phenomenon. Later, in order to achieve industrial production, scientists created a coagulation product composed of dilute sulfuric acid and sulfate, thus realizing the current large-scale production of viscose fibers, and thus many of the viscose fibers we see now are produced. Beautiful, cool clothing made of viscose fiber. After seeing this, everyone should have some understanding of what kind of fabric viscose fiber is.
So, what kind of fabric is viscose? Generally speaking, viscose fiber fabric has the essence of cotton fabric and also has good silk quality. It is an authentic ecological fiber fabric. Viscose fiber is derived from nature and is superior to nature. Because viscose fiber is optimized by using the shorter velvet of cotton as raw material, viscose fiber is essentially more pure than cotton fiber. For example, the cellulose content of viscose fiber is over 99.5%, while cotton fiber only hovers around 95% to 97%.
Main varieties of viscose:
1. General viscose fiber
(1) Viscose-cotton short fiber cutting length is 35~40mm, fineness is 1.1~2.8dtex (1.0~2.5 denier) and cotton blended chemical fiber fabric can be made into fine cloth, regular denim , gabardine, etc.
(2) Viscose wool-type short fiber, cut length 51~76mm, fineness 3.3~6.6dtex (3.0~6.0 denier), can be spun purely, or blended with wool and chemical fiber fabrics , can be used to make tweed, coats, etc.
2. Rich and strong fiber
(1) It is an improved variety of viscose fiber.
(2) Pure spinning can be made into fine cloth, poplin, etc.
(3) Blended chemical fiber fabrics such as cotton and polyester to produce various work clothes.
(4) It has good alkali resistance, the woven fabric is stiff, will not shrink or deform after cleaning, and is relatively durable.
3. Viscose silk
(1) Can be used as work clothes, quilt covers, bedding and decorations.
(2) Viscose yarn and cotton yarn are interlaced to make feather yarn and thread quilt top.
(3) Viscose silk and silk are interlaced to make georgette, brocade, etc.
(4) Viscose threads are interlaced with polyester and brocade filaments to make crystal satin, antique satin, etc.
4. Viscose strong yarn
(1) The strength is twice as high as that of ordinary viscose yarn.
(2) Twisted and woven into cord fabric, used for automobile, tractor and carriage tires.
5. High crimp and high wet modulus viscose fiber
High curl and high wet modulus viscose fiber (expressed as HR) is a new generation of viscose fiber. It has high strength and wet modulus, moderate elongation and good Curling performance, coupled with the fact that viscose fiber itself has excellent hygroscopicity, air permeability, no static electricity, good coloring performance, fineness and length can be adjusted sensitively, it is a kind of cloth fiber raw material with relatively comprehensive performance. Use it to purify according to different needs. The hygroscopic performance and coloring performance of viscose fiber are closely related to the fact that the fiber itself contains a large number of hydroxyl groups (—OH). The hydroxyl (—OH) group absorbs a large number of water molecules or other molecules and absorbs them.The wetter the fiber, the better it will color. Because viscose fiber has experienced many physical and chemical reactions during the manufacturing process, the cellulose macromolecules are cracked, making the macromolecules shorter, with larger molecular gaps and looser arrangements. The hydroxyl groups (—OH) in the molecules But its polarity is good, and it is better than cotton in these aspects. Therefore, the colorability of viscose fiber is better than that of cotton. It is not only suitable for many dyes and has a wide color spectrum, but also the colors can be brightly colored.
As for acetate fiber (including diacetate fiber and triacetate fiber), which is also a cellulose regenerated fiber, their coloring properties are significantly inferior to viscose fiber. This is because most of the hydroxyl groups (-OH) in the acetate fiber molecules are acetylated and become hydrophobic groups. Therefore, the dyes that can be used on viscose fiber and cotton are not necessarily usable. It can be seen that among cellulose fibers, viscose fiber also has good colorability and is easy to color, and the cost of printing and dyeing is also low. Viscose fiber also has shortcomings in printing and dyeing. For example, like cellulose fibers such as cotton, it can be widely used with reactive dyes. Although reactive dyes can replace some harmful chemical dyes, they form a lot of colored sewage during the printing and dyeing process. Other viscose fibers are not as good as some synthetic fibers in terms of dye fastness and light fastness for certain prints and dyes. Although this is related to the dye properties and process, viscose fiber is still a major advantage due to its ease of dyeing, full color spectrum, bright color, and low cost.
It is precisely because of the pure nature of viscose fiber that it can withstand full sun exposure, moth-proof, high temperature resistance, is not allergic to chemicals, and has good resistance to meltable solvents and mold , Therefore, among the current main fabric fiber fabrics, the performance of viscose fabric is particularly comprehensive.
