1.Lightweight: Polypropylene fiber has a low density (about 0.91g/cm³), making fabrics made from it much lighter than those of cotton, polyester, or nylon with the same thickness.

2.Excellent Moisture Wicking: It has very low moisture absorption (the moisture regain is only about 0.03%), so it can quickly transfer sweat and moisture from the body surface to the fabric surface for evaporation, keeping the skin dry.

3.Good Chemical Resistance: It is resistant to most acids, alkalis, and organic solvents, and is not easily corroded, so it has a long service life in harsh chemical environments.

4.Abrasion Resistance: The fabric has good wear resistance and durability, and is not easy to be worn or damaged during daily use.

5.Thermal Insulation: Due to its lightweight and hollow structure (for some varieties), it can trap air well, thus having certain thermal insulation properties.
