Detailed Professional Description

Polypropylene (PP) Yarn is a lightweight, high-performance synthetic filament known for its hydrophobic properties and low specific gravity. It is the lightest of all synthetic fibers, even floating on water. PP yarn offers excellent thermal insulation, chemical resistance, and is inherently resistant to stains and odors. Because it does not absorb moisture, it is the ideal choice for activewear and industrial applications where dryness and chemical stability are paramount.

Application Fields

  • Activewear: The preferred choice for thermal base layers and moisture-wicking sports gear.

  • Industrial Filtration: Used in acid and alkali-resistant filter cloths and bags.

  • Ropes & Cordage: Ideal for marine ropes and industrial safety nets due to its floatability.

  • Medical Textiles: Applied in disposable surgical masks, gowns, and hygiene products.

Color & Dyeing Methods

All our Polypropylene yarns are Dope Dyed. Because the fiber cannot be dyed after spinning, pigments are added directly to the melt. This results in 100% color fastness that will never bleed or fade, making it perfect for high-performance apparel and industrial uses where color integrity is critical.
