Spunmelt Five Beam SMMSS Line
In 2009, CL built China's first five-beam SMMSS line. The SMMSS fabric consists of three layers of spunbond nonwoven fabric and two layers of meltblown nonwoven fabric. It is versatile and used in producing nonwoven materials for medical applications such as surgical gowns, protective clothing, masks, and drapes. Additionally, it is highly suitable for hygiene products such as top sheets, back sheets, core wraps, leg cuffs, and more for diapers and sanitary napkins.

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/SSS PP spun bond products and SMMSS PP spunmelt products, which can be converted according to different market positioning and customer needs.
SMMSS sorting: S1 → M1 →M2 → S2 → S3 from the web former to the direction of the calender.
