Under the background of vigorously advocating the concept of green environmental protection, China's functional polypropylene staple fiber is ushering in a new development opportunity.

The first is because of the nature of the fiber itself. Conventional polypropylene yarns are widely used in clothing, construction and other industries due to their low density, high strength, acid and alkali resistance. Among the current major fiber varieties, polypropylene has certain advantages in production cost and production technology. The comprehensive consumption of polypropylene yarn in production is relatively small, and the process is simple and pollution-free.

Secondly, the application field of polypropylene yarn has been expanding in recent years. At the beginning of production, polypropylene yarns are only used in the fields of carpets, ropes, etc. However, with the rapid development of the economy, various functions of polypropylene yarns are being continuously explored, and the application fields of newly developed series products are expanding.

Previously, most of the domestic functional polypropylene staple fiber enterprises were small-scale production, and the integrity of the system could not be achieved. However, after 10 years of development, some polypropylene yarn manufacturers have formed an operation system integrating production and sales, and their ability to develop new functional polypropylene staple fibers has also been greatly improved.

A new trend is that dyeable functional polypropylene staple fibers are being sought after by the market and are welcomed by many outdoor sports brand designers in Europe and America. In fact, functional polypropylene staple fiber has always been an ideal material for outdoor sportswear because of its light weight, fast drying, warmth and natural antibacterial function. However, its biggest drawback was its inability to dye, which also restricted its application. In recent years, dyeable functional polypropylene staple fiber and rear-end series derivative products have been introduced. Many domestic spinning, knitting, printing and dyeing enterprises have also reached strategic partnerships with dyeable polypropylene fiber manufacturers to Downstream products are quickly introduced to the world market and earn their own profits.

From the perspective of foreign markets, the United States has developed a variety of functional polypropylene staple fibers, such as antibacterial, flame retardant, antistatic, and antifouling, 10 years ago. Western European countries have also successfully developed conductive, electric, and bioabsorbable polypropylene. In particular, Japan has been increasing its investment in the development of functional polypropylene staple fibers and high-performance fibers, and has continuously introduced high-tech new products, emphasizing its use in decoration and industrial applications, and broadening the application fields of textiles. Japan's polypropylene functional textiles account for about 40% of all textiles, and even higher proportions. Japan's Mitsubishi first introduced the environmentally friendly polypropylene "Mitsubishi Pylen".

There is no weak market, only weak products. At present, the development and application of fine-denier polypropylene filament yarn as a garment fabric is becoming more and more diversified all over the world. For example, American filament fiber technology company, Los Shara-tes knitting company, coville company and other leading enterprises have won consumption through their own special products. Favorite (see Table 4). China's polypropylene fiber industry should continue to develop in the future, accelerate the elimination of production capacity that does not have competitive strength, and retain those advanced equipment and high-quality production capacity with competitive strength, especially on the basis of ensuring effective production capacity, and more development and production conform to modern society. And products that are needed at home and abroad.
