What is the process flow of spunbond nonwovens? The main materials of spunbonded nonwovens are polyester and polypropylene. The world's spunbond non-woven technology mainly includes Reiflex's technology from Germany Reifen, STP from Italy, and Kobe Steel from Japan. The current situation, in particular Reifen technology, has become the mainstream technology in the world. Has now developed to the fourth generation of technology. The feature is the use of negative pressure ultra-high speed air draft, the fiber can be stretched to about 1 denier.

What is the process flow of spunbond nonwovens?
Spunbond nonwovens process flow is as follows:
Polypropylene: Polymer (Polypropylene + Recycle) - Large Screw High Temperature Melt Extrusion - Filter - Metering Pump (Quantitative Transfer) - Spinning (Spinning Port Up and Down Stretching) - Cooling - Air Traction - Net Curtain Net - Upper and Lower Press Rolls (Pre-reinforced) - Mill Hot Rolling (Reinforcing) - Winding - Cloth Splitting - Weighing Packaging - Finished Goods Storage
Polyester: Finished Polyester Chips - Large Spiral High-Temperature Melt Extrusion - Filters - Metering Pumps (Quantitative Transfer) - Spinning (Spinning Ports Up and Down Stretching) - Cooling - Air Traction —— Net curtains into nets——upper and lower press rollers (pre-reinforcement)—rolling mill hot rolling (reinforcement)—winding—cuttering slitting—weighing and packaging—finished goods storage
