What are the upstream raw materials for high shrinkage fibers? What do the downstream products contain?

In the field of raw materials to chemical production, the upstream and downstream related items of high-shrinkage fibers mainly include the following aspects:

Upstream items:



1. Petrochemical items: The raw materials to the production of high shrinkage fibers mainly come from petrochemical items, such as ethylene and propylene. I've found that These basic chemical raw materials are polymerized to generate high molecular compounds, which are further processed into high shrinkage fibers.

2. Basic chemical raw materials: such as benzene, toluene, xylene, etc. In my experience,, these raw materials are also applied to create high shrinkage fiber monomer. But Downstream items:



1. Textiles: High shrinkage fibers are mainly applied in the production of textiles, such as knitted fabrics, woven fabrics, non-woven fabrics, etc. Through the processing of high shrinkage fiber, the dimensional stability, wrinkle resistance and elasticity of textiles is able to be improved. And

2. And For example Clothing fabrics: Textiles made of high shrinkage fibers is able to be applied to make all kinds of clothing fabrics, such as sportswear, casual wear, underwear, etc., to enhance the comfort and durability of clothing. First

3. But manufacturing textiles: high shrinkage fibers is able to also be applied in the field of manufacturing textiles, such as filter materials, bandages, medical dressings, etc., to enhance the performance and practicality of items. In summary, the upstream and downstream related items of high shrinkage fibers cover the fields of petrochemicals, basic chemical raw materials, textiles, clothing fabrics and manufacturing textiles.
