As we all know, viscose fiber, as the most widely used regenerated fiber among chemical fibers, has its own unique characteristics. Its main characteristics include good spinnability, pure spinning, and blending with various fibers; its main characteristics are: The fabric has the advantages of drapeability, moisture absorption and breathability, good dyeing performance, anti-static, and UV resistance. However, its shortcomings are equally prominent, such as high moisture regain of viscose fiber, low fiber strength, lower wet strength, only about half of dry strength, so the fabric has poor stability, is not wear-resistant, and the shrinkage of the finished fabric is difficult to control, etc. . However, it has advantages that other fibers do not have in terms of performance, price and output. It is still making contributions to the textile industry, industry and aviation in the continuous upgrading.
Viscose fiber is made of cotton linters and wood as raw materials, and is made into soluble fiber through alkalinization, aging, sulfonation and other processes. Cellulose xanthate is dissolved in dilute alkali solution to make viscose and is made by wet spinning. The entire viscose staple fiber production process can basically be completed within 24 hours. At present, China is the largest producer of viscose fiber in the world, accounting for about 70% of global viscose production, with an annual output of nearly 4 million tons. Domestic viscose fiber mainly uses cotton linters as the main raw material.
Viscose staple fiber is the most widely used regenerated cellulose fiber, which can be seen everywhere in our lives, and its use in textiles The use of viscose fabrics is the most prominent in the clothing industry. Let’s learn about the advantages and disadvantages of viscose fabrics.
1. Viscose has good hygroscopicity, breathability and good drape.
2. The viscose fabric is smooth and soft, with a silky feel and a smooth hand feel.
3. It has excellent dyeing properties. After dyeing, the color is bright, the color fastness is good, and it is not suitable for fading.
4. Viscose fabrics are not prone to static electricity, their adsorption properties meet the needs of human skin, meet national Class II safety standards, and are biodegradable .
1. Viscose fabric feels heavy, has poor elasticity, is prone to wrinkles, and is not stiff.
2. Viscose fabrics are not resistant to washing and wear, and have poor dimensional stability.
3. Not acid-resistant.
Viscose fiber is widely used in the production of textiles and various types of clothing due to its good properties. And with the continuous improvement of people’s living standards and the pursuit of nature, cotton production can no longer meet the growing market demand. However, viscose fiber not only has the essence of cotton but also has the elegance and softness of silk, is easy to dye, anti-static, and resistant to high temperatures. , antibacterial, and can be ironed-free through finishing. However, most synthetic fibers cannot have both of these, and viscose fiber has the most comprehensive plasticity. Modal, Tencel, bamboo fiber, etc. are all upgraded versions of viscose fiber, and can also be produced with various functional differences according to needs. Chemical viscose fiber, so the future of viscose fiber is still promising. It is generally optimistic in the textile industry and is expected to usher in a more brilliant tomorrow.
