What is the important role of PP yarn in our lives?

First, the characteristics of PP yarn:

1. Form: The longitudinal direction of the polypropylene is smooth and the cross section is round.

2. Density: The advantage of polypropylene is that it is light in texture and its density is only 0.91g/cm3, which is a lighter density among common chemical fibers.

3. Extensibility: Polypropylene filament has high strength, large elongation, high initial modulus and excellent elasticity. Therefore, PP yarn has good wear resistance. In addition, the wet strength of polypropylene filaments is basically equal to dry strength.

4. Hygroscopicity and Dyeability: PP yarn has little hygroscopicity and is almost non-hygroscopic. The moisture regain under atmospheric conditions is close to zero. 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.

5. Acid and alkali resistance: PP yarn has good chemical resistance. In addition to concentrated nitric acid and concentrated caustic soda, PP yarn has good resistance to acid and alkali.

6. Light resistance: 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.

Second, the advantages of PP yarn:

Good gloss, colorful, easy to clean, no fading, low cost, environmental protection, light weight, anti-aging, acid and alkali resistance, light weight, wear resistance, low thermal conductivity, seawater corrosion resistance, uniform thickness, no moisture absorption, breakage, etc.

Third, PP yarn use:

1. Widely used in weaving various knitwear such as hosiery, gloves, sweaters, knit pants, etc.

2. It is widely used in dishwashing cloth, mosquito net cloth, woven fabric, warm packing, carpet backing, paste wall fabric, curtain, furniture cloth, luggage, canvas, rope and belt fishing gear, geotextile and so on.

3. It can also be processed into textile products such as luggage belt, Simmons fabric, curtain fabric, backpack belt, sofa cloth, handbag belt, mobile phone strap, decorative cloth, all kinds of webbing and woven rope sling.
