Recycled polyester fibers for polyester fibers

Regenerated fibers are mainly divided into two categories: regenerated cellulose fibers and regenerated synthetic fibers. Viscose fiber is the earliest regenerated fiber, and new regenerated cellulose fibers such as Lyocell fiber, cellulose urethane fiber, superconducting viscose fiber, kapok fiber and bamboo fiber have appeared successively. Polyester fibers account for about 70% of synthetic fibers, and the application of polyester in the bottle industry is rapidly expanding, so recycled synthetic fibers are dominated by recycled polyester fibers.
