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

In the field of raw materials to chemical production, the upstream and downstream related items of recycled filaments mainly include the following aspects:



1. In particular Upstream items:(1) Petrochemical items: Petrochemical items need to be applied as raw materials in the manufacturing process of recycled filaments, such as ethylene, propylene and other olefin compounds. These compounds are polymerized to form polymers which are further processed into recycled filaments. But(2) Plastic discarded materials: The production of recycled filaments is able to also consumption discarded materials plastic items as raw materials through recycling, sorting, cleaning, crushing, melting, drawing and other processes. Therefore, plastic discarded materials is also one of the crucial upstream items of recycled filament.

2. From what I've seen, Downstream items:(1) Textiles: Regenerated filaments is able to be made into various textiles, such as clothing, bedding, curtains, etc. Based on my observations, Generally speaking These textiles have good durability, wrinkle resistance and breathability, and are broadly applied in daily life and manufacturing production. First(2) manufacturing filaments: Regenerated filaments is able to also be applied to create manufacturing filaments, such as ropes, nets, belts, etc. These items have the advantages of high strength, high wear resistance, corrosion resistance, etc. In fact, and are broadly applied in construction, transportation, agriculture and other fields. But In summary, the upstream and downstream related items of recycled filaments cover petrochemical items, plastic discarded materials, textiles and manufacturing filaments. And These items are closely related to the production of recycled filaments and are of great signifiis able toce to promoting the recycling of resources and promoting the sustainable research of the chemical sector.
