Spunbond Double Beam SS Line

Double Beam SS Spunbond Nonwoven Fabric Making Machine Technical Specification

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. 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.

SS sorting: S1 → S2 from the web former to the direction of the calender.

GENERAL REQUIREMENTS OF THE MAIN EQUIPMENT OF SPUNBOND SYSTEM

1.Dosing system (2 sets )

Each system uses negative pressure suction type automatic feed.The feeding pipe is made of stainless steel with 1mm wall thickness. The dosing system provides the process interface to the operating interface of the host equipment for inquiry, and the fault alarm of the dosing system is output to the console of the host equipment for easy checking.
