Read： 601 Time：20months ago Source：Transform the World with Simplicity

Viscose staple fiber is an important raw material for chemical production, which has a wide range of properties and uses. This article will detail the nature of viscose staple fiber, production process, use and development prospects.

1. the properties of viscose staple fiber

viscose staple fiber is a kind of regenerated cellulose fiber with many excellent properties. First of all, it has good moisture absorption, can absorb and retain a large amount of moisture, and keep the fabric comfortable and breathable. Secondly, viscose staple fiber has good thermal stability and chemical stability, and can maintain stable properties under certain temperature and pH conditions. In addition, viscose staple fiber also has good dyeability and biodegradability, making it widely used in textiles and papermaking.

the production process of 2. viscose staple fiber
the production process of
viscose staple fiber mainly includes pulp preparation, alkali cellulose preparation, aging, yellowing, dissolution, ripening, spinning, drafting, cutting and other processes. Among them, pulp preparation is the key link in the production of viscose staple fiber, mainly wood, cotton linters and other raw materials are processed into pulp that meets the requirements. Alkali cellulose preparation is the process of converting cellulose in pulp into alkali cellulose. The subsequent process is the alkali cellulose aging, yellowing, dissolution and other processing, and finally through spinning, drawing, cutting and other processes to make viscose staple fiber.

3. the use of viscose staple fiber

viscose staple fiber as an important chemical raw material, has been widely used in various fields. First of all, in the field of textiles, viscose staple fiber is an important material for making various garments, home textiles and industrial textiles. Because of its good moisture absorption, breathability and dyeing, viscose staple fiber has an irreplaceable position in the field of textiles. Secondly, in the field of papermaking, viscose staple fiber can be used as a reinforcing agent and filler to improve the strength and texture of paper. In addition, viscose staple fibers can also be used to manufacture non-woven fabrics, filter materials, insulating materials, etc.

4. the development prospects of viscose staple fiber

With the continuous progress of science and technology and the improvement of environmental awareness, the development prospects of viscose staple fiber are very broad. First of all, in the field of textiles, people have higher and higher requirements for comfort and health. As a green and environmentally friendly fiber material, viscose staple fiber will receive more and more attention. Secondly, in the field of papermaking, with the improvement of national environmental protection requirements, viscose staple fiber, as a biodegradable material, will have a greater market space. In addition, with the continuous emergence of new technologies, the production process and performance of viscose staple fiber will be further improved, providing more possibilities for applications in various fields.

In short, viscose staple fiber, as an important raw material for chemical production, has been widely used in various fields. With the continuous progress of science and technology and the improvement of environmental awareness, the development prospect of viscose staple fiber is very broad.
