I plant wholesale sales of polypropylene fiber, many types, low prices, the current rapid development of the polypropylene industry, then what is the characteristics of polypropylene fiber?

1. Polypropylene form: polypropylene longitudinal surface smooth, cross-section was round.
2. Polypropylene fiber density: polypropylene is the biggest advantage of light texture, its density is only 0.91g / cm3 is the most common chemical fiber in the lightest varieties.
3. Polypropylene fiber strength: polypropylene fiber high strength, elongation, the initial modulus is higher, excellent flexibility. So good wear resistance of polypropylene. In addition, the wet strength of polypropylene fiber is basically equal to dry strength.
4. Polypropylene fiber hygroscopicity and dyeing: the absorption of polypropylene is very small, almost no moisture, the general conditions of moisture regain near zero. But it has wicking action, through the fabric of the capillary to pass water vapor, itself can not afford any absorption.
5. Polypropylene fiber acid and alkali resistance: polypropylene has good resistance to chemical corrosion, in addition to concentrated nitric acid, concentrated caustic soda, the polypropylene on the acid and alkali resistance is good.
6. Polypropylene fiber Lightfastness: polypropylene light resistance is poor, thermal stability is also poor, easy aging, intolerant ironing. But can be added by adding anti-aging agent in the spinning, to improve its anti-aging properties. In addition, the electrical insulation of polypropylene is good, but easy to produce static electricity during processing.
