The development trend of polypropylene industry

(1) Green environmental protection promotes the development of polypropylene

In recent years, the country has vigorously promoted the development of green industries and has tightened environmental protection requirements. The green manufacturing of polypropylene will usher in new development opportunities. Since polypropylene fiber cannot be dyed, it usually uses masterbatch for pre-spinning coloring, and a specific color can be obtained after spinning and forming. Therefore, there is no need for printing and dyeing in the downstream production process, which avoids the pollution of the environment by the waste liquid generated in the dyeing process, and significantly improves The degree of environmental protection of textiles, so polypropylene has environmentally friendly characteristics. In addition, people are paying more and more attention to the ecological environment. As a green fiber, polypropylene will be more easily favored by consumers. In the context of green environmental protection, the polypropylene fiber industry will enter a new period of development.

(2) The application field of polypropylene fiber continues to expand and penetrate

With the increase of residents’ disposable income, the improvement of living standards, and the increasing emphasis on environmental protection, the application market of polypropylene fiber continues to expand. It has successively developed high-strength, flame-retardant, anti-static, anti-fouling, anti-ultraviolet, anti-aging, and far-infrared , Conductive and other differentiated polypropylene fibers, as well as fine denier, ultra-fine denier, profiled cross-section polypropylene fibers, etc. In addition, polypropylene composite fibers, such as sea-island polypropylene composite fibers and sheath-core structure polypropylene composite fibers, are also a direction for the development and application of polypropylene technology. Polypropylene composite fiber technology promotes the application of polypropylene in lithium-ion battery separators and new luggage fabrics, high-end tents, assault boats, and floating rafts.

In recent years, with the rise of cutting-edge technologies such as nanotechnology, microcapsule technology, and electronic information technology, smart fibers have developed rapidly. The development of smart polypropylene fibers can not only endow traditional fibers with new functions, but also open up the applications of fibers in high-tech fields such as solar cells, aerospace, and biomedicine.
