Viscose filament has an important position in the field of chemical production raw materials, and its upstream and downstream related products are rich and diverse. This article will detail the upstream and downstream associated products of viscose filament.

upstream related products:

1. wood pulp: one of the main raw materials for the production of viscose filament is wood pulp, which is made of wood chips cooking and extracting fibers, and its fiber quality has an important impact on the production and quality of viscose filament.
2. Caustic soda: The production process of viscose filaments requires the use of caustic soda as a catalyst to promote the chemical reaction of cellulose.
3. Carbon disulfide: In the production of viscose filament, carbon disulfide plays a key role as a solvent and reducing agent.

downstream related products:

1. Textiles: Viscose filament has good moisture absorption, breathability, softness and gloss, so it is often used to produce various textiles, such as shirts, skirts, underwear, etc.
2. Non-woven fabric: Viscose filament can also be used to produce non-woven fabrics. Non-woven fabrics have the characteristics of good air permeability, strong moisture absorption, and high softness. They are widely used in sanitary materials, filter materials and other fields.
3. Industrial wire: Viscose filament is also widely used in the industrial field, such as the production of tire cord, conveyor belt, filter cloth, etc.

From the above introduction, it can be seen that the upstream and downstream related products of viscose filament cover many fields and have a wide range of applications. At the same time, the continuous improvement and development of the production process and technology of viscose filament also provides more possibilities and support for the development of upstream and downstream industries. In the actual production process of

, viscose filament manufacturers need to pay close attention to the development of upstream and downstream industries and changes in market demand in order to adjust production plans and strategies in a timely manner to maintain the stability and sustainability of production. At the same time, it is also necessary to strengthen communication and cooperation with upstream and downstream enterprises to promote the coordinated development and win-win situation of the industrial chain.

In short, the upstream and downstream related products of viscose filament are rich and diverse, which provide important support and guarantee for the development of chemical production raw materials.
