What are the performance characteristics of PP FDY yarn?

PP FDY yarn:

1. The longitudinal surface of the PP FDY yarn is straight and smooth with a circular cross section.

2. The biggest advantage of PP FDY yarn is its light weight. Its density is only 0.91g/cm3, which is the lightest of the common chemical fibers.

3. The PP FDY yarn has high strength, large elongation, high initial modulus and excellent elasticity. Therefore, polypropylene has good wear resistance. In addition, the wet strength of polypropylene filaments is basically equal to dry strength.

4. Hygroscopicity and Dyeability: Polypropylene has little hygroscopicity and is almost non-hygroscopic. The moisture regain under normal atmospheric conditions is close to zero. However, it has a wicking action and can transfer water vapor through the capillary in the fabric, and does not have any absorption by itself.

5. Acid and alkali resistance: Polypropylene has good chemical resistance. In addition to concentrated nitric acid and concentrated caustic soda, polypropylene has good resistance to acid and alkali.

6. Light fastness: PP FDY yarn has poor light resistance, poor thermal stability, easy aging and is not resistant to ironing. However, it is possible to improve the anti-aging property by adding an anti-aging agent at the time of spinning. In addition, polypropylene has good electrical insulation, but it is easy to generate static electricity during processing.
