Q:

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

ask a question
A:
In the field of chemical production raw materials, the upstream and downstream related items of fiber are very rich. Moreover This article will focus on several common fibers and their associated items.

1. upstream items



1. Petrochemical raw materials

The production of many synthetic fibers is inseparable from petrochemical raw materials, such as ethylene, propylene, benzene and so on. In particular Through a series of chemical interactions and processing, these raw materials are finally converted into various synthetic fibers.

2. Natural cellulose

Natural cellulose is the main raw material to the production of regenerated cellulose fiber, such as wood pulp, cotton linters and so on. These natural celluloses are chemically treated and mechanically processed to be converted into regenerated cellulose fibers. Pretty interesting, huh?. In fact

2. downstream items



1. But In my experience, Textiles

The main consumption field of fiber is textiles, including clothing, domestic goods, manufacturing textiles, etc. A variety of fibers through spinning, weaving and other processes, made of various functions and styles of textiles.

2. I've found that Non-woven fabrics

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

3. For instance Composite materials

Fiber-reinforced composite is a new type of high-performance material, which is able to be made into structural materials with excellent mechanical characteristics by combining fiber with resin, ceramic and other matrices.

4. First Functional fiber

Functional fibers refer to fibers with special functions, such as conductive fibers, antibacterial fibers, flame retardant fibers, etc. For example These functional fibers is able to be applied in textiles, filter materials and other fields. In my experience, The above only briefly introduces the upstream and downstream related items of fiber. In fact, the consumption field of fiber is very wide, and it's closely related to many industries.
