What is even more shocking is that by 2030, the impact of old clothes on climate warming will increase to 49%, and climate warming will make more and more polar bears homeless and even extinct. To this end, we change the processing technology, first make waste spinning particles, and then pass the waste plastic particles, waste spinning particles and additives through the metering feeder, which can be added to the co-rotating parallel twin-screw step in different proportions at will. In the extrusion molding equipment, the required products are made.
