A polypropylene civilian purposes: Can pure spin or wool, cotton or viscose and other blended to produce a variety of mixed woven fabrics. Can be used to weave all kinds of knitwear such as hosiery, gloves, sweaters, knit pants, wash cloth, mosquito netting, wadding, warm fillers, such as wet diapers.
Non-woven polypropylene
Industrial uses: carpets, fishing nets, canvas, hoses, concrete reinforcing materials, industrial fabrics, non-woven fabrics. Such as carpets, industrial fabric, rope, fishing nets, construction reinforcement materials, oil and other blankets and upholstery. Further, polypropylene film fibers may be used as packaging material. Polypropylene dynamic
II. Polypropylene market prospects
As a rising star of polypropylene synthetic fiber developed rapidly in recent years. Since the 1980s, the world's polypropylene production to more than 9 percent annual growth rate, much higher than the 7.3 percent polyester and synthetic growth rate of 4.6%. Affected by the world financial crisis, the synthetic growth slowed down significantly, but polypropylene production remained at an average annual rate of 5.5%, polypropylene demand also remained the growth trend.
According to the US authorities to statistics, the current annual production capacity for polypropylene production in the world and about 5.6 million tons, respectively, and 500 million tons, production capacity and spinning fibers and are about 4 million tons and 3.3 million tons. Expected by the end of 2001, the polyolefin fiber production capacity will reach nearly 700 million tons, including spinning fiber production capacity of about 4.5 million tons. According to the analysis, the rapid development of polypropylene production driven mainly by growth in demand for its production and demand growth rate is roughly equal. The current demand for polypropylene fibers, including films, including split about 500 million tons / year, after removal of the film split fiber, polypropylene demand at 3.3 million tons -350 tons.
Distribution of polypropylene from the market point of view, the world's polypropylene (not including the split-fiber) distribution of the ratio of the application is basically a carpet production accounts for about 45%, industry and the health sector accounts for about 40 percent, accounted for 12% of decorative, clothing accounts for 3 %. The main application areas are developed polypropylene carpet industry and industrial areas, such as the United States accounts for about 60% polypropylene carpet total consumption of Polypropylene (PP carpet where the vehicle with a larger amount of use), accounting for 35 percent of industrial and medical, household accounts 4%, less the amount of clothing; Western Europe carpets, industrial and decorative accounted for 95% of the amount of polypropylene, clothing accounts for 4 percent; Asia's rapid economic growth in countries and regions, although polypropylene production started late, but rapid development, especially many Asian population, the demand in the health sector is large, public health and consumer consumption is much higher than the proportion of non-woven United States and Europe.
Experts believe that the future will further speed expanded polypropylene market, particularly in the field of non-woven fabrics (mainly industrial, healthcare and engineering). Simultaneously with the development of technology polypropylene modified polypropylene textile sector are also some alternative to other synthetic varieties, such as propylene have low-cost, easy processing, good hydrophobic properties, so that in the original acrylic and polyester have cotton, wool market has begun to place, and the trend of expansion. In addition, high-grade polypropylene carpets can be processed through a modified or combined with other fiber composite, and then compete with nylon.
The next 10 years, the world will still be higher than other synthetic polypropylene, although the ability to slow down the growth rate, but it will remain at around 4 percent, output and demand growth of about 5%. In addition to East Asia, Southeast Asia, the rapid rise of the petrochemical industry in the region continues to grow, the Middle East, Southeast Asia, the rapid rise of the petrochemical industry in the region will also be a new and rapidly growing area. By then, not including the film world, including the split-fiber polypropylene production capacity, production and demand will exceed film lun, nylon.
