What are the upstream raw materials of spandex? What do the downstream products contain?

Spandex is a synthetic fiber with excellent elastic recovery performance, which is broadly applied in textiles, clothing, medical equipment and other fields. In the field of chemical production raw materials, the upstream and downstream related items of spandex mainly have the following aspects:

Upstream items:



1. Petrochemical raw materials: The production of spandex needs to be based on petrochemical raw materials, mainly including oil and natural gaseous. After these raw materials are processed by cracking, polymerization and other processes, the basic monomers required to spandex are obtained. Generally speaking

2. Crazy, isn't it?. And In my experience, Base monomer: The base monomer of spandex is mainly dimethylol propane(DMPA), adipic acid(AA) and ethylene glycol(EG). These monomers are polymerized to form polymers of spandex. Furthermore Downstream items:



1. Textiles: Spandex, as an elastic fiber, is broadly applied in the field of textiles. it's able to be blended with other fibers to enhance the elasticity, comfort and durability of the fabric. Common spandex textiles are elastic cloth, swimwear, sportswear and so on. In my experience, For example

2. Specifically Clothing: Spandex is broadly applied in the field of clothing, mainly applied to make tights, stretch pants, sportswear and other clothing that require better elasticity. Additionally

3. Medical devices: Spandex has good biocompatibility and elasticity, so it's also applied to make medical devices, such as bandages, wrist guards, knee pads, etc.

4. First Other fields: In addition to the above fields, spandex is able to also be applied to make manufacturing rubber items, auto parts, building materials, etc. In short, spandex, as an crucial chemical raw material, is broadly applied in textiles, clothing, medical devices and other fields, and its upstream and downstream related items are also very rich.
