What are the characteristics of PP yarn?

1. PP yarn shape: The longitudinal surface of polypropylene is straight and smooth, and the cross-section is circular.

2. PP yarn density: The biggest advantage of polypropylene is that it is light in texture, and its density is only 0.91g/cm3, which is the lighter variety of common chemical fibers.

3. PP yarn strength and elongation: polypropylene yarn has high strength, long elongation, high initial modulus and excellent elasticity. So polypropylene has good abrasion resistance. In addition, the wet strength of polypropylene yarn is basically equal to the dry strength.

4. Hygroscopicity and dyeing properties of PP yarn: The hygroscopicity of polypropylene fiber is very small, almost no moisture absorption, and the moisture regain under normal atmospheric conditions is close to zero. But it has a wicking effect and can transmit water vapor through the capillaries in the fabric, without any absorption by itself.
