Polypropylene staple fiber is a fluffy fiber with a specified fineness and length that is made from polypropylene resin as the main raw material and undergoes melt spinning, drafting, crimping, drying, shaping, cutting, and packaging.

Polypropylene short fiber uses:

Polypropylene staple fiber is widely used in sanitary non-woven fabrics, needle-punched carpets, needle-punched non-woven fabrics, automotive interior fabrics, geotextiles, filter cloths, clothing interlinings, filter yarns, electric blankets and other fields. It can also be combined with cotton, artificial Fiber blends.

Polypropylene staple fiber specifications:

1.5D*38mm, 9D*51mm, 3D*51mm, 18D*51mm, 1.5D*51mm, 3D*64mm, 8D*102mm, 6D*90mm, 2D*38mm, 2D*51mm, 18D and other conventional varieties, as well as special specifications Can be produced and customized according to customer requirements.

Characteristics of polypropylene staple fiber:

1. Low density

Among all synthetic fibers, the density of polypropylene short fiber is relatively low, about 0.91g/cm3, so it is very light in weight and covers a large area per unit weight of fiber.

2. High strength. Polypropylene short fiber has high strength, strong curl elasticity, low melting point, good surface air permeability, and better acid and alkali resistance and wear resistance than other fibers.

3. Wear-resistant and corrosion-resistant

The plane wear resistance of polypropylene short fiber is second only to nylon, and its corrosion resistance: it has obvious stability to inorganic acids and alkali.

4. Almost no moisture absorption.

Polypropylene staple fiber has excellent moisture conductivity, flexibility, excellent web-forming and carding properties, and excellent thermal adhesion. It absorbs almost no moisture, has a moisture regain of less than 0.03%, has a small fabric shrinkage, and has a strong wicking effect of fine-denier polypropylene fiber.

5. Has excellent electrical conductivity and thermal insulation

Polypropylene staple fiber has high resistivity (710cm) and low thermal conductivity. Compared with other chemical fibers, polypropylene has good electrical insulation and thermal insulation properties.
