SSMMSS Nonwoven Fabric Making Machine

SMMSS Nonwoven Fabric Making Machine Technical Specification

(CL's Exclusive Patent Technology - Double Web Design)

PRODUCTION LINE OVERVIEW

This nonwoven fabric making machine is used for the production of non woven fabrics through the process of PP spinning, web forming, and thermal bonding reinforcement. Using PP as the main raw material, along with additives such as color master batch, antioxidants, anti-pilling agents, and flame retardants, we produce non woven fabrics with different colors, properties, and suitable for various applications. This production line can produce SS/SSSS PP spun bond products and SMMSS PP spunmelt products, which can be converted according to different market positioning and customer needs.

SSMMSS sorting: S1 →S2 → M1 →M2 → S3 → S4 from the web former to the direction of the calender.
