What are the chemical properties of Intermingled PP FDY?
1. The longitudinal surface of the Intermingled PP FDY is straight and smooth with a circular cross section.
2. The advantage of Intermingled PP FDY is that it has a light texture and its density is only 0.91g/cm3, which is a lighter density among common chemical fibers.
3. The Intermingled PP FDY 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: Intermingled PP FDY has little hygroscopicity and is almost non-hygroscopic. The moisture regain rate under single 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: Intermingled PP FDY has good chemical resistance. In addition to concentrated nitric acid and concentrated caustic soda, polypropylene has good resistance to acid and alkali.
6. Light resistance: Intermingled PP FDY 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.
Guangdong Mengtai High-tech Fiber Co., Ltd. is a professional manufacturer, manufacturer and seller of polypropylene fiber. Since its establishment, it has developed steadily. At present, more than 70 polypropylene FDY production lines, 8 POY production lines, 2 DTY production lines and other production and R&D equipment have been established. The annual production of polypropylene filaments with different specifications and functions exceeds 30,000 tons. A polypropylene filament manufacturer with a large domestic production.
