Polypropylene shaped fibers can be classified based on their cross-sectional geometry and structural design. Each type offers unique performance advantages for different applications.

Multi-Lobal Fibers

Multi-lobal fibers, such as trilobal, cross-shaped, and five-lobal fibers, are designed to improve light reflection and surface area. These structures enhance luster and can create silk-like or metallic visual effects.

Flat Fibers

Flat or ribbon-shaped fibers have a wider surface area, which improves coverage and reduces friction. These fibers are often used in applications requiring smooth texture and reduced pilling.

Hollow Fibers

Hollow shaped fibers, including hollow cross-shaped or multi-void structures, contain internal air spaces. These spaces improve thermal insulation, reduce weight, and increase bulkiness, making them suitable for filling materials and insulation products.

Composite Shaped Fibers

Composite fibers, such as side-by-side or core-sheath structures, combine different materials or structures to achieve multiple functional properties, including improved strength, elasticity, or thermal performance.
