Viscose staple fiber is an important raw material for chemical production, which is widely used in textile, paper, medicine, food and other fields. Its upstream and downstream related products are numerous, which will be described in detail below.

Upstream Associated Products:

1. Wood: The main raw material of viscose staple fiber is wood, especially the mixed pulp of coniferous trees and hardwood trees. The cellulose in the wood is extracted and processed into viscose staple fiber through chemical reaction.
2. Caustic soda: Caustic soda is an important raw material in the production process of viscose staple fiber, which is used to adjust the pH value of the solution and promote the chemical reaction of cellulose.
3. Carbon disulfide: Carbon disulfide is used as a solvent in the production of viscose staple fiber to help convert cellulose into spinnable viscose.

downstream related products:

1. Textiles: Viscose staple fiber is an important raw material for textiles. Mixing with other fibers (such as cotton, wool, silk, etc.) can improve the moisture absorption, breathability and comfort of the fabric.
2. Non-woven fabrics: Viscose staple fibers can be used to produce non-woven fabrics, which are widely used in sanitary materials, filter materials, thermal insulation materials and other fields.
3. Papermaking: Viscose staple fiber can be used as a reinforcing agent for papermaking to improve the strength and toughness of paper.
4. medicine, food field: viscose staple fiber can be used in the production of medicine and food packaging materials, as well as medical equipment.

Generally speaking, viscose staple fiber plays an important role in the field of chemical production raw materials, and its upstream and downstream related products are extensive, involving many fields. With the continuous development of science and technology, the application field of viscose staple fiber will continue to expand.
