The process flow of PET non-woven fabric production process

1. Melting of PET particles

Put PET particles into a high-temperature melting machine, heat the PET particles to a certain temperature, and melt them into a liquid state.

2. Spinning process

The molten PET liquid is spun through a spinning machine. The spinning machine sprays liquid PET through fine pores, forming thin and long continuous fibers

3. Mesh forming

The spun PET fibers are meshed on the conveyor belt. The grid structure on the conveyor belt interweaves fibers to form a uniform fiber network

4. Precompression

After the mesh is formed, the PET fiber mesh undergoes a pre compression process. By heating and compacting, the fiber mesh is made tighter, improving its strength and stability

5. Hot air shaping

The pre compressed PET fiber mesh enters the hot air shaping chamber. In the shaping chamber, the PET fiber mesh is blown by high-temperature hot air, and the fiber surface begins to melt and bond together, forming a non-woven fabric.

6. Cooling

After hot air shaping, PET non-woven fabric is quickly cooled through a cooling device. Cooling can make PET non-woven fabric more durable and improve its tensile strength

7. Winding

The cooled PET non-woven fabric is wound through a winding device. Roll PET non-woven fabric into larger rolls for subsequent processing and use

8. Cutting

PET non-woven fabric wound into rolls can be cut according to needs. Cutting can cut PET non-woven fabric into the required size and shape for different applications.

9. Post processing

The cut PET non-woven fabric can undergo post-processing. Post processing includes processes such as processing, printing, and lamination, with different treatments according to specific needs to meet different application requirements.

The above is the production process of PET non-woven fabric. Through melting, spinning, mesh forming pre compression, hot air setting, cooling, winding, cutting, and post-processing, PET particles are ultimately transformed into high-strength and environmentally friendly PET non-woven fabrics, widely used in various fields. With the continuous development of technology, the production process of PET non-woven fabric is also constantly improving and innovating to meet market demand and environmental requirements
