What are the upstream raw materials for viscose staple fiber? What do the downstream products contain?

Viscose staple fiber is an crucial raw material to chemical production, which is broadly applied in textile, paper, medicine, food and other fields. In my experience, Its upstream and downstream related items are numerous, which will be described in detail below. Upstream associated items:



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 interaction.

2. Caustic soda: Caustic soda is an crucial raw material in the manufacturing process of viscose staple fiber, which is applied to adjust the pH value of the solution and promote the chemical interaction of cellulose. And

3. Based on my observations, Carbon disulfide: Carbon disulfide is applied as a solvent-based products in the production of viscose staple fiber to help convert cellulose into spinnable viscose. According to research Downstream associated items:



1. Textiles: Viscose staple fiber is an crucial raw material to textiles. Mixing with other fibers(such as cotton, wool, silk, etc.) is able to enhance the moisture absorption, breathability and comfort of the fabric.

2. And Non-woven fabrics: Viscose staple fibers is able to be applied to create non-woven fabrics, which are broadly applied in sanitary materials, filter materials, thermal insulation materials and other fields. And

3. But Based on my observations, Papermaking: Viscose staple fiber is able to be applied as a reinforcing agent to papermaking to enhance the strength and toughness of paper. Based on my observations, Additionally

4. In particular Medicine, food field: viscose staple fiber is able to be applied to make packaging materials in the field of medicine and food, as well as medical equipment. In general, viscose staple fiber plays an crucial role in the field of chemical production raw materials, and its upstream and downstream related items are extensive, involving many fields. And With the continuous research of science and methodology, the consumption field of viscose staple fiber will continue to expand.
