Key Properties of Polypropylene Twisted Yarn

View: 2003/25/2026  

Polypropylene twisted yarn is widely used in industrial applications due to its enhanced strength, structural stability and improved processing performance achieved through the twisting process.

High Strength

Twisting improves inter-filament cohesion, resulting in higher tensile strength and better load-bearing capacity. Compared with untwisted yarn, it provides improved structural integrity for demanding applications.

Lightweight

With a density of approximately 0.91 g/cm³, polypropylene is one of the lightest synthetic fibers. PP twisted yarn maintains this advantage, making finished products easier to handle, transport and install.

Low Thermal Shrinkage

Featuring low and uniform thermal shrinkage, polypropylene twisted yarn ensures good dimensional stability during processing and end use.

Chemical and Corrosion Resistance

The yarn shows strong resistance to acids, alkalis and various corrosive environments, including seawater. It performs reliably in industrial and marine conditions.

Abrasion Resistance and Durability

PP twisted yarn performs well under friction and repeated use, providing a long service life in demanding working environments.

Color Stability

Polypropylene twisted yarn offers consistent color distribution and good color fastness, supporting stable appearance in finished products.
