Polyester recycling material spunbonded nonwoven fabric production process

The invention discloses a polyester recycling material spunbonded non-woven fabric production process, which comprises the following steps: polyester recycling material pretreatment, melting, adding crystal nucleating agent, extrusion, melt filtration, spinning, airflow drawing Stretch, put into a net or directly into the net. The invention utilizes the polyester recycling material to produce various kinds of spunbonded non-woven fabrics. Under the same weight, the non-woven fabrics produced by the present invention are obtained in the aspects of breaking strength, breaking force, tear strength and the like. Significant improvements have been made, and product performance indicators have completely met the performance targets of spunbond nonwovens produced using polyester chips. Due to the production process of the present invention, from the screening of raw materials to the final production, it is continuously completed in one production process, the production efficiency is greatly improved, and the production cost is further reduced.
