1. Different performance
1. The strength and other properties of recycled polyester fiber are poor.
2. The strength and other properties of polyester fiber are relatively good.
2. Different raw materials
1. Recycled polyester is re-granulated with recycled materials (PET bottle flakes, foam, etc.), and then drawn into fibers.
2. Polyester is made of chemical raw materials PTA and MEG by polymerization and esterification drawing into fiber.
Recycled polyester staple fiber is made of polyester fabric, waste polyester bottle flakes, spinning waste silk, foam material, pulp block as raw materials. The waste bottle flakes are crushed and washed, and the mixture of various materials is dried, melted, extruded, and spun Silk, winding, bundling, drafting, crimping (at the same time adding different oils when crimping according to customer needs), relaxation and heat setting, and cutting to form polyester staple fibers of different lengths.
