PRODUCTION LINE OVERVIEW

This nonwoven fabric making machine is designed to produce nonwoven fabrics through the processes of PP spinning, web forming, and thermal bonding. Using PP as the primary raw material, it incorporates additives such as color master batches, antioxidants, anti-pilling agents, and flame retardants. The production line is versatile, capable of producing PP spunbond nonwoven fabrics in various colors and properties, suitable for a wide range of applications. It can produce three-layer SSSS PP spunbond products, which can be tailored to meet different market positions and customer requirements.

SSSS sorting: S1 → S2 → S3→ S4 from the web forming machine to the direction of the calender.
