Spunbond Triple Beam SSS Line

Three Beam SSS Spunbond Nonwoven Fabric Making Machine Technical Specification

PRODUCTION LINE OVERVIEW

This SSS Nonwoven fabric making machine is used for the production of non woven fabrics through the process of PP spinning, web forming, and thermal bonding. It primarily uses PP as the main raw material, along with additives such as color master batch, antioxidants, anti-pilling agents, and flame retardants. The production line is capable of producing PP spunbond non woven fabrics of different colors, properties, and suitable for various applications. This production line can produce both three-layer SSS PP spunbond products , which can be converted according to different market positioning and customer needs.

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