In the field of chemical production raw materials, the upstream and downstream related products of fiber are very rich. This article will focus on several common fibers and their associated products.

1. upstream product

1. Petrochemical raw material

Many synthetic fibers are inseparable from petrochemical raw materials, such as ethylene, propylene, benzene and so on. Through a series of chemical reactions and processing, these raw materials are finally converted into various synthetic fibers.

2. natural cellulose

natural cellulose is the main raw material for the production of regenerated cellulose fiber, such as wood pulp, cotton linter and so on. These natural celluloses are chemically treated and mechanically processed to be converted into regenerated cellulose fibers.

2. Downstream Products

1. Textile
The main application field of
fibers is textiles, including clothing, household goods, industrial textiles, etc. A variety of fibers through spinning, weaving and other processes, made of various functions and styles of textiles.

2. Non-woven

non-woven fabric is a non-woven material made of fibers by bonding, hot pressing and other methods. Non-woven fabrics are widely used in hygiene, filtration, insulation and other fields.

3.
of composites
fiber reinforced composites is a new type of high-performance material, which can be made into structural materials with excellent mechanical properties by combining fibers with resin, ceramic and other matrices.

4. functional fibers

functional fibers refer to fibers with special functions, such as conductive fibers, antibacterial fibers, flame retardant fibers, etc. These functional fibers can be used in textiles, filter materials and other fields.
The above
only briefly introduces the upstream and downstream related products of fibers. In fact, the application fields of fibers are very wide and are closely related to many industries.
