PP yarn and polypropylene yarn are also called polypropylene high-strength yarn, PP yarn/polypropylene yarn and polypropylene colored yarn/polypropylene high-strength yarn are mainly used for webbing, rope

Polypropylene yarn and polypropylene colored yarn/polypropylene general-strength yarn can also be used for various civilian webbing such as mobile phone straps, shoe laces and backpack belts. The specifications of pp yarn/polypropylene colored yarn/polypropylene strong yarn, polypropylene yarn; 300D, 450D, 600D, 900D, 1000D, etc. There are now nearly ten thousand kinds of color polypropylene yarns for customers to choose, and polypropylene can also be customized according to customer needs Polypropylene yarn in various colors. The webbing and rope woven with pp yarn/polypropylene yarn can be used for all kinds of luggage belts, travel bags, backpacks, shoelaces, mobile phone straps and so on. Belts woven from polypropylene yarn with special properties can be used as car seat belts, seat belts for mountaineering, high-altitude and offshore operations, and gas car binding belts. Christmas yarn products are to be used for Christmas trees.

The performance characteristics of PP yarn have the following aspects:

Form: The longitudinal surface of polypropylene is straight and smooth, and the cross section is round;

Density: The biggest advantage of polypropylene is its light texture. Its density is only 0.91g/cm3, which is the lightest variety among common chemical fibers.

Strength and elongation: Polypropylene fiber has high strength, large elongation, high initial modulus and excellent elasticity. Therefore, polypropylene fiber has good abrasion resistance. In addition, the wet strength of polypropylene yarn is basically equal to the dry strength.

Hygroscopicity and dyeability: Polypropylene has very little hygroscopicity, almost no moisture absorption, and the moisture regain under general atmospheric conditions is close to zero. But it has a wicking effect, can transfer water vapor through the capillary in the fabric, and does not have any absorption effect by itself.

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

Light resistance: Polypropylene fiber has poor light resistance, poor thermal stability, easy aging, and is not resistant to ironing. However, the anti-aging performance can be improved by adding anti-aging agent during spinning. In addition, polypropylene fiber has good electrical insulation, but it is easy to generate static electricity during processing.

The superior performance of PP yarn is a kind of chemical fiber material often used in our life and production.
