Physical properties of PP FDY yarn
What are the physical properties of PP FDY yarn?
1. Shape of PP FDY yarn: the longitudinal surface of polypropylene is straight and smooth, and the cross section is round.
2. PP FDY yarn density: the greater advantage of polypropylene is light texture, its density is only 0.91g/cm3 is a common chemical fiber density of light varieties.
3. PP FDY yarn stretching strength: Polypropylene wire high strength, large elongation, high initial modulus, good elasticity. So polypropylene wear well. In addition, the wet strength of polypropylene filament is basically equal to the dry strength.
