Imported PP polypropylene filament non-woven fabrics. Among the many manufacturing methods of non-woven fabrics, due to the obvious advantages in product performance and production efficiency made by the spunbond method, it has gained worldwide popularity in the past 20 years. Impressive rapid development.
About 40% to 50% of non-woven fabric production currently uses melt spinning methods (including spunbonding methods, melt-blown methods and composite methods of the two).
?The process flow of imported PP polypropylene filament non-woven fabrics: polymer (polypropylene + recycled material) – large screw high-temperature melt extrusion – filter – metering pump (quantitative conveying) – spinning ( Up and down stretching and suction at the spinning entrance) – Cooling – Air traction – Net curtain forming – Upper and lower pressure rollers (pre-reinforcement) – Hot rolling in the rolling mill (reinforcement) – Winding – Reverse cloth slitting – – Weighing and packaging – finished products are put into storage.
Imported PP polypropylene filament non-woven fabric has good heat resistance, with a melting point of 164~170℃, and the products can be sterilized at temperatures above 100℃.
It will not deform at 150℃ without being affected by external force.
The embrittlement temperature is -35°C. Embrittlement will occur below -35°C, and the heat resistance is not as good as PE.
? It is an environmentally friendly new material manufacturer integrating R&D, production, customization and sales.
The company has always implemented the tenet of “quality first, reputation first”, with strong technical force, strict management system, brand-new production equipment, and complete testing instruments to ensure that everything puts the interests of users first and provides users with high-quality products. Technology, high quality, high performance, high level products.
