[0002] Regenerated fiber refers to textile fiber that is inspired by silk spinning, using natural polymer compounds such as cellulose and protein as raw materials, chemically processed into a concentrated polymer solution, and then spun and post-treated. Regenerated fiber synthetic leather is made of regenerated fiber. No toxic organic solvents are required in the production of regenerated fiber synthetic leather. The raw fiber synthetic leather in the production line is continuous and uninterrupted. Compared with animal leather, leather made from regenerated fiber is environmentally friendly, safe and low-cost.

[0003] Synthetic leather needs to be polished before production is completed. During the polishing process, a large amount of lint and dust will be generated, which are easy to fly in the workshop and affect the workshop environment.
