Operation Process of Spunbond Nonwoven Production Line


To produce spunbond non-woven fabrics with excellent performance, every step in the operation process of the spunbond non-woven fabric production line is indispensable. This article will specifically introduce the operating procedures of the spunbond nonwoven production line.

Operation Process of Spunbond Nonwoven Production Line
the performance and characteristics of the automated spunbond non-woven equipment

There are many production processes for spunbond nonwovens, but the main processes are basically the same. If you want to produce spunbond non-woven fabrics with excellent performance, you cannot miss every step in the following operating procedures.

1. Preparation of raw and auxiliary materials

This process mainly refers to the preparation and pretreatment of raw materials for production. PP raw materials can be directly put into the production system without pretreatment. All other raw materials, such as PET, PA, PILA, etc., must be dried before they can be put into use.

2. Conveying

The conveying process includes the two processes of sending "wet slices" (raw materials) from the storage location to the drying system for processing and conveying the dried "dry slices" to the production line for use.

3. Measuring and mixing process

The function of this process is to mix various raw and auxiliary materials uniformly with each other in the proportion required by the process, and then enter the production system and transport it.

4. Extrusion and melting process

The function of this step is to process the solid raw material into a viscous fluid melt.

5. Melt filtering device

The function of the device is to remove impurities in the melt and protect the safety of the system.

6. Metering

The role of metering is to provide a melt with stable pressure and uniform flow for the spinning device.

7. Spinning process

This process is to change the high-temperature melt into a trickle of melt.

8. Cooling device

The function of the device is to cool and lower the temperature of the high-temperature melt stream, making it a fiber with stable performance.

9. Drafting

Drafting can increase the orientation and crystallinity of the molecular arrangement in the fiber, and improve the mechanical and physical properties of the fiber.

10. Laying process

The function of this process is to spread out the messy fibers into a uniform and continuous fiber web.

11. Fabrication process

This process uses a certain method to consolidate and set the scattered fiber web into a non-woven fabric with practical value.

12. Finishing

Finishing can give products specific functions. Generally, drying equipment is also arranged downstream of the finishing equipment to remove excess moisture in the product, this part of the equipment is not a necessary process device.

13. Online detection device

The device can dynamically detect the quality of the product when the production line is in operation, and the online detection device is not the basic configuration of the production line.

14. Rolling process

This process is to collect the non-woven fabrics in rolls and become products that are delivered to the market or processed in the next process.


The purpose of slitting is to process the full-width, continuous non-woven products produced into the specifications required by the market (roll length
And width) products. In low-speed, small-scale production lines, the slitting function can be directly completed on the winding machine.

Choosing high-quality spunbonded non-woven equipment can make the operation of the above processes more convenient and production efficiency will be higher.
