Low Cost: Due to the affordable price of polypropylene raw materials and a simple production process, polypropylene yarn is relatively inexpensive ...

The primary raw material is polypropylene (PP) chips/pellets, which require high purity and a uniform molecular weight distribution.

Polypropylene yarn has a density of only 0.91 g/cm³, making it the lightest among common chemical fibers.

Lightweight: Polypropylene yarn has a density of only 0.91 g/cm³, making it the lightest among common chemical fibers;

using yarn that is too fine can lead to breakage, while yarn that is too coarse can compromise the fabric's smoothness.

The production process of polyester yarn primarily involves steps such as melt conveyance, spinning, and winding.

Polyester yarn offers advantages such as high strength, abrasion resistance, good elasticity, and resistance to chemical corrosion.

Polyester fiber refers to a type of fiber produced by spinning polymers that contain ester groups in their main chains;
