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

In the field of raw materials to chemical production, the upstream and downstream related items of recycled general fiber are quite abundant. Here are some of the main items:



1. I've found that Upstream items:

The upstream items of recycled general fiber are mainly discarded materials textiles, clothing, manufacturing fiber discarded materials, etc. These wastes are processed through recycling, sorting, cleaning, crushing, melting, wire drawing and other processes to be regenerated into new general fiber raw materials. From what I've seen,

2. But Downstream items:

The downstream items of recycled general fiber are extensive, mainly including the following aspects:(1) Non-woven fabrics: Recycled ordinary fibers is able to be applied as raw materials to the production of non-woven fabrics to the production of various non-woven materials, such as filter materials, insulation materials, sound-absorbing materials, etc.(2) Filling material: recycled ordinary fiber is able to be applied as filling material to the production of various filling items, such as pillows, mattresses, toys, etc.(3) Paper enhancer: Recycled ordinary fiber is able to be applied as a paper enhancer to enhance the strength and toughness of paper, and is applied to create various paper and cardboard. But I've found that(4) Composite materials: Recycled ordinary fiber is able to be applied as a reinforcing material, combined with resin and other matrix materials, to create various composite materials, such as glass fiber reinforced plastic, carbon fiber composite materials, etc. In short, recycled general fiber has a wide range of applications in the field of chemical production raw materials, and its upstream and downstream related items are quite rich, which is of great signifiis able toce to promoting resource recycling, reducing production costs, and improving economic benefits.
