What is the performance of polypropylene fabrics and polypropylene fabrics?

Polypropylene fibers are synthetic fibers spun from isotactic polypropylene obtained by the polymerization of propylene. In our country, the brand name is polypropylene. Polypropylene began its industrial production in 1957. Because the raw material is propylene, its source is extremely rich, its cost is low, and its production process is simple. It is currently the most inexpensive synthetic fiber. Polypropylene has good performance and rapid development. Its worldwide production ranks second only to polyester, polyamide, and acrylic. Polypropylene has the characteristics of small density, low melting point, high strength, and resistance to acid and alkali, so polypropylene is mainly used in the fields of industry, interior decoration, clothing and non-woven fabrics.

Polypropylene's main products include staple fibers, filaments, non-woven fabrics, cigarette tow and bulked continuous filaments (BCF) for packaging, cigarette filters, carpets, nonwovens, apparel and other products. In addition to taking, industrial polypropylene is the most active market, and consumption in medical and hygiene materials is also growing rapidly.

Polypropylene fabrics have the advantages of high strength, relative density, low moisture absorption, and good corrosion resistance. The disadvantage of polypropylene fabrics is that since polypropylene is composed of highly crystallized bodies that have a neat array, there are few polar genes and there are no genes that have the ability to react. Therefore, dyeing is extremely difficult. The use of liquid spinning, can solve the problem of difficult dyeing. In addition, the light resistance of polypropylene is poor. Polypropylene in the hot season, after prolonged exposure to sunlight, easy to aging, and low strength. Especially when it is wet, it is even more serious. Therefore, polypropylene fabrics and blended fabrics should not be dried in the sun after washing, but should be placed in a cool, ventilated place to dry. Polypropylene tends to age at high temperatures, so the thermal stability of the fiber is not good enough.
