What material is PP yarn?

PP yarn refers to polypropylene yarn, also known as polypropylene strong filament. The following is a detailed introduction about PP yarn:

characteristic:

Form: The longitudinal surface is straight and smooth, and the cross-section is circular.

Density: Light in texture, with a density of only 0.91g/cm 3, it is a common type of chemical fiber with a lighter density.

Stretchability: High strength, elongation, high initial modulus, excellent elasticity, good wear resistance, wet strength equal to dry strength.

Moisture absorption and dyeing properties: The moisture absorption is very low, almost no moisture absorption, and the moisture regain under general atmospheric conditions is close to zero, but it has a core absorption effect and can transmit water vapor through the capillaries in the fabric, without any absorption effect itself.

Acid and alkali resistance: Outstanding resistance to acid and alkali.

Light resistance: poor light resistance, poor thermal stability, easy aging, and not resistant to ironing, but its anti-aging function can be improved by adding antioxidant during spinning.

Purpose:

Ribbons and ropes: can be used for various civilian woven straps such as mobile phone straps, shoelaces, backpack straps, various luggage straps, travel bags, as well as special purpose straps such as car seat belts, mountain climbing seat belts, high-altitude and offshore work seat belts, car binding belts, etc.

Other fields: It is also applied in industries such as construction, packaging, and sports equipment, for example, it can be used to make protective nets, packaging tapes, sports equipment, etc.
