High-purity polymer

The polypropylene monomer undergoes a polymerization reaction to form high-molecular-weight PP, ensuring the stability and uniformity of the white particles during processing. 

Modification and whitening treatment

Add an appropriate amount of whitening agent or filler to improve the optical properties, making the particles appear white, while maintaining mechanical and thermal properties. 

Melt granulation

Through melt extrusion, the material is cooled and cut into granules, ensuring uniform particle size and suitable for continuous and automated production. 

Non-woven fabric processing 

Spunbond method: Molten PP is extruded through a spinneret and laid onto a net, then heated and pressed to form non-woven fabric. 

Meltblown method: High-speed extrusion forms ultra-fine fibers, enhancing filtration and breathability properties. 

Needle-punching method: PP fibers are interlaced to form a thick non-woven fabric, enhancing mechanical strength. 

Post-treatment and functionalization

Through coating, dyeing or additive modification, antibacterial, waterproof, anti-static and flame-retardant functions can be achieved, meeting various requirements. 

V. Performance Testing and Standards

The performance testing of PP white non-woven fabric particles ensures the quality of the finished product: 

Mechanical properties: Testing of tensile strength, tear strength and wear resistance. 

Physical properties: Fiber diameter, fabric thickness, porosity and breathability tests.
