What is the process flow of spunbonded non-woven fabrics? The main materials of spunbonded non-woven fabrics are polyester and polypropylene. The world's spunbonded non-woven fabric technology mainly includes lecofel technology from Germany, STP Technology from Italy, Kobe Steel technology from Japan, etc. The current situation, especially Laifen technology, has become the mainstream technology in the world. At present, it has developed to the fourth generation technology. It is characterized by negative pressure ultra-high speed airflow drafting, and the fiber can be stretched to about 1 Danier. What is the process flow of spunbonded non-woven fabrics? The process flow of spunbonded non-woven fabrics is as follows: polypropylene: Polymer (Polypropylene, return)--Large screw high temperature melt extrusion--Filter--Metering pump (Quantitative delivery)--Spinning (Spinning inlet up and down stretching suction)--Cooling--Airflow traction--Mesh--Up and down Roller (Pre-reinforcement)--Rolling Mill hot rolling (Reinforcement)--Winding--Split--Weighing package--Finished product warehousing polyester: processed polyester slices--Large screw stalk high temperature melting extrusion--Filter--Metering pump (Quantitative delivery)--Spinning (Spinning inlet up and down stretching suction)--Cooling--Airflow traction--Mesh--Up and down Roller (Pre-reinforcement)--Rolling Mill hot rolling (Reinforcement)--Winding--Split--Weighing package--Finished product storage
