DHP419 Series High-strength Polypropylene Yarn Stretching Machine

The high-strength Polypropylene Yarn Stretching Machine is mainly used for spinning high-strength polypropylene long filaments ranging from 300 to 1800 denier. The product is fully oriented drawn filament (FDY). The strength of the single filament can reach over 7.0g/D. Its raw material is polypropylene chips.

Polypropylene high-strength filament is mainly used in: industrial sewing thread, hoisting rope, geotextile, ship rope and cable, conveyor belt, fire hose, safety and protective belt net and other fields.
