We should be familiar with polypropylene filaments. Its application in our life is very frequent. Because polypropylene has a simple production process and its price is very low, polypropylene has developed very fast.

So what do we know about polypropylene filaments?

The strength of polypropylene filament is very high, and the elasticity is also very good, so the abrasion resistance of polypropylene filament is also very good. The wet strength of polypropylene is basically equal to dry strength, so he is the ideal material for making fishing nets and cables, and the moisture absorption of polypropylene. Sex is very small, he basically does not absorb moisture.

The moisture regain rate under normal atmospheric conditions is close to zero. However, it has a wicking action that transfers water vapor through the capillary in the fabric, but does not itself absorb any absorption. The dyeability of polypropylene is poor, and the chromatogram is not complete, but the method of coloring the original liquid can be used to make up for the deficiency.

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. Polypropylene 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.
