polypropylene staple fiber is made from polypropylene resin through advanced processes such as melt spinning, drawing and crimping, and has the following core advantages:

Lightweight and high strength: With a density of only 0.9 to 0.92 g/cm, it is 20% lighter than polyamide fibers, yet its strength and wear resistance are significantly superior to those of traditional fibers. It maintains stable performance in both dry and wet conditions and is suitable for high-strength applications.

Outstanding chemical stability: resistant to acid and alkali corrosion, resistant to microbial erosion, not moldy or worm-eaten, especially suitable for demanding environments such as medical and filtration.

Environmental protection and energy conservation: The production process features low energy consumption and recyclability, aligning with the national "dual carbon" strategy. The addition of color masterbatches enables direct coloring of the original liquid, reducing pollution from subsequent dyeing processes and meeting the demands of green manufacturing.

Functionalized innovation: By integrating technologies such as flame-retardant masterbatches and UV-resistant additives, we develop special fibers with properties like fire resistance and aging resistance, thereby expanding into high-end application fields.
