What is the stretchability of pp yarn?

Published: [2019/2/19] Views: [517]

The strength of the pp yarn is very high, and the elasticity is also very good. Therefore, the abrasion resistance of the pp yarn is also very good. The wet strength of the polypropylene is basically equal to the dry strength, so it is an ideal material for making fishing nets and cables, and polypropylene. The hygroscopicity is very small and it is basically not hygroscopic.


The moisture regain rate under single atmospheric conditions is close to zero. However, the pp yarn has a wicking action, which can transfer water vapor through the capillary in the fabric, but does not have any absorption effect by itself. The dyeability of pp yarn 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.


The pp yarn has a wicking action, which 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.
