The main physical and chemical properties of polypropylene staple fiber:

1. Form The longitudinal plane of polypropylene fiber is straight and smooth, and the cross-section is circular.

2. Density The advantage of polypropylene fiber is its light texture, its density is only 0.91g/cm³ it is a lighter variety among common chemical fibers, so polypropylene fiber of the same weight can obtain a higher coverage area than other fibers.

3. Strong elongation Polypropylene has high strength, long elongation, high initial modulus and excellent elasticity. So polypropylene has good abrasion resistance. In addition, the wet strength of polypropylene is basically equal to the dry strength, so it is an ideal material for making fishing nets and cables.

4. Light hygroscopicity and dyeing properties, good warmth retention; almost no moisture absorption, but strong wicking ability, obvious moisture absorption and perspiration; polypropylene has very little moisture absorption, almost no moisture absorption, and the moisture regain under general atmospheric conditions is close to zero . But it has a wicking effect, passing water vapour through the capillaries in the fabric, but does not have any absorption effect on its own. Polypropylene has poor dyeability and incomplete chromatogram, but it can be compensated by the method of dope dyeing.

5. Acid and alkali resistance Polypropylene has good chemical resistance. Except for concentrated nitric acid and concentrated caustic soda, polypropylene has good resistance to acid and alkali, so it is suitable for use as filter material and packaging material.

High strength The strength of polypropylene elastic yarn is second only to that of nylon, but the price is only one-third of that of nylon; the fabric is dimensionally stable, wear-resistant and elastic, and has good chemical stability. However, it has poor thermal stability, is not resistant to sunlight, and is prone to aging and brittle damage. For this reason, anti-aging agents are often added to polypropylene.
