IV. Preparation and Processing Technology of PP Nonwoven White Particles

Raw material polymerization and modification

High molecular PP is formed through the polymerization of polypropylene monomers. Then, based on different applications, modification agents such as heat-resistant agents, antioxidants, flame retardants, or fillers are added to enhance the material properties. 

Melt Extrusion and Granulation

After the modified PP is melted uniformly, it is cooled and cut by an extruder to form granules that are uniform in size and have a pure white color. This results in a raw material of PP non-woven fabric with uniform particles and a bright white color. 

Non-woven fabric forming processing 

Spunbond method: PP molten fibers are directly laid out in a net-like structure, and then heated and pressed to form non-woven fabric. 

Meltblown method: By using high-speed extrusion to form ultra-fine fibers, the filtration performance is enhanced. 

Needle-punching method: The PP fibers are needle-punched into a fabric-like form to increase thickness and strength. 

Post-processing and functionalization

According to the application requirements, processes such as dyeing, coating, or adding functional additives (such as antibacterial agents, waterproofing agents, etc.) can be carried out to achieve multifunctional non-woven fabrics. 

V. Performance Testing and Standards

To ensure the quality of the finished products produced by the PP non-woven fabric white particle process, systematic testing is required: 

Mechanical properties: tensile strength, tear strength and pressure resistance. 

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

Thermal properties: Heat distortion temperature and high-temperature resistance. 

Environmental protection indicators: Compliant with RoHS, REACH and non-toxic and harmless standards, ensuring safety for medical and personal care applications.
