Preparation of raw and auxiliary materials

It mainly refers to the preparation and pretreatment of raw materials for non-woven fabric production. PP raw materials can be directly put into production system without pretreatment, while some other raw materials, such as PET, PA, PLA, etc., need to be dried before they can be put into use.


Transportation (automatic feeding)

The conveying process includes two processes: sending the "wet slice" (raw material) from the storage place to the drying system for treatment and transporting the dried "dry slice" to the production line for use.


Metering mixture
The function of this process is to mix various raw and auxiliary materials evenly according to the proportion required by the process, enter the production system and transport them to the screw extruder for processing.


Melt extrusion
The function of this process is to process solid raw materials into viscous melt.


Melt filtration
This function is to remove impurities in the melt and protect the safety of the system.



Melt metering
The metering function is to provide melt with stable pressure and uniform flow for the spinning device.


Spinning Die Process
This process is to change the high-temperature melt into melt trickle.


Cooling and Stectching Diffuser
The function of the cooling device is to cool the high-temperature melt trickle and make it a fiber with stable performance.
Drafting diffusion can increase the molecular alignment, orientation and crystallinity in the fiber, and improve the mechanical and physical properties of the fiber.




Mesh laying process

This process is to lay the disordered nonwoven fibers to form a uniform and continuous fiber web.



Embossing bonding
This process is to use a certain method to consolidate and shape the scattered fiber mesh.



Post processing
After treatment can give products specific functions. Generally, drying equipment is arranged downstream of the finishing equipment to remove excess water in the products. This part of equipment is not a necessary process device.


On line detection device
The device can dynamically detect the product quality when the production line is running, and the on-line detection device is not the basic configuration of the production line.


Winding
This process is to collect nonwoven fabric in rolls and become products to be delivered to the market or processed in the next process.
Slitting
The purpose of slitting is to process the full width and continuous nonwoven fabric produced into the products with the specifications (roll length and width) required by the market. In the low-speed and small production line, the slitting function can be completed directly on the winding machine and the.
Although the machines produced by different types of manufacturers are different, according to the working principle, except for the differences in spinning, cooling, drafting and mesh laying methods, other production process principles and equipment are basically the same.
