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.
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.
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.
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.
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.
