What are the advantages of polypropylene staple fibers that make their unique properties stand out in the chemical fiber industry?

Polypropylene staple fiber stands out in the chemical fiber industry with its unique properties. This kind of fiber is made of polypropylene as raw material through melting, spinning, drawing, cutting and other processes, and has many advantages. Polypropylene short fiber has a small density and light texture, and is the lowest density of all common chemical fibers. This feature makes polypropylene lighter in the production of products with the same coverage area, so it is widely used in the production of lightweight clothing and non-woven products.

Polypropylene staple fiber also has excellent strength and wear resistance. Its high strength, good elasticity, even in the wet state can maintain the original strength, which makes the product made of polypropylene durable, especially suitable for the production of fishing nets, ropes and other wear-resistant items.

Polypropylene staple fibers have superior moisture conductivity and thermal adhesion, which can quickly transfer sweat from the skin surface to the fabric, keeping it dry and comfortable. At the same time, it also has good chemical resistance, in addition to strong nitric acid and strong alkali, has good resistance to most chemical substances, suitable for the production of filter materials and packaging materials.

Light weight: The density of polypropylene short fiber is 0.9~0.92 grams/cubic centimeter, which is the lightest in all synthetic fibers, 20% lighter than polyamide fiber, 30% lighter than polyester fiber, 40% lighter than viscose fiber.

High strength: the strength of polypropylene staple fiber is high in dry and wet state, and the wear resistance and resilience are good.

Anti-microbial: Polypropylene staple fiber has anti-microbial properties and does not develop mold or moth.

Good chemical resistance: The chemical resistance of polypropylene staple fiber is better than that of general synthetic fiber.

Good electrical insulation: The electrical resistivity of polypropylene staple fiber is very high (7×1019 ohms · cm), so it has good electrical insulation.

Good heat preservation: the thermal conductivity of polypropylene short fiber is very small, and the heat preservation is excellent.

Good moisture conductivity and flexibility: polypropylene staple fiber has superior moisture conductivity, flexibility, mesh and carding properties, and excellent thermal adhesion. The surface permeability is good.

Good anti-cracking effect: polypropylene staple fiber has more anti-cracking effect, strong structural effect, good permeability resistance, and is an effective rigid waterproof material.
