Problems solved by technology

[0002] The traditional method of producing polyester staple fiber uses raw polyester chips as raw material. The raw material is characterized by high purity, stable viscosity, and low water content. The production process is short. The specific process is raw material-test-screening-drying-screw melting Extrusion—first-stage filtration—spinning—winding—drawing—crimping—drying and setting—finished product packaging, the disadvantage is high cost and large consumption of oil resources. In order to reduce costs, waste PET bottles with low cost can be used as raw materials. Production
