A Chinese product name for synthetic fibers such as the use of petroleum refined by-product propylene as raw materials. Also known as polypropylene fibers. According to the data, the process of polypropylene fiber downstream industries will enter a new round of boom cycles, which brings the expansion of the polypropylene fiber market demand. The sales resection of the polypropylene fiber industry is obvious, the supply and demand relationship is improved, and the industry profitability is steadily improved. At the same time, under the generous needle of the National "Twelfth Five-Year Plan" and industrial structure, the polypropylene fiber faces huge market investment opportunities, and the industry is expected to usher in a new opportunity.

A Chinese product name for synthetic fibers such as the use of petroleum refined by-product propylene as raw materials. Also known as polypropylene fibers. The raw material has a rich source of raw materials, simple production process, low product price is relatively low in other synthetic fibers. The physical mechanical properties of the fibers are: high strength (4 to 6 g of short fibers, filament is 5 ~ 8 g / d), the wet strength and dry strength are substantially the same, small specific gravity (0.91), wear resistance Corrosion, etc. World Polypropylene Fibrobi Yield has exceeded 1 million tons in 1980.

The polyester staple fiber is made of polypropylene resin as the main raw material, which is made into color and colorless, defined, defined, and the length of fluffy fibers. Since the polypropylene is unsaptive and the shrinkage rate is small, the polyester staple fiber  has easy washing. Polypropylene heat resistance is poor, and the shrinkage is started at 100 ° C. When the water washed, the temperature is not too high, otherwise it will cause shrinkage, deformation, and even melt. The hot iron temperature is 90-100 ° C, and a layer of pad is required or steam hot. The polypropylene has excellent chemicals, insects and mold.

Polyester staple fiber s have high strength, high toughness, good chemical resistance and antimicrobial and low prices, so widely in ropes, fishnet, seat belts, safety nets, luggage belts, filter cloth, cable foreskin, Papermaking felt and paper enhanced materials, polyester staple fibers can also be made into civil construction and water conservancy projects.

In addition, the propylene cigarettes can be used as cigarette filters, polypropylene fiber nonwoven fabric, such as sanitary napkins, surgical jackets, hats, masks, bedding, diaper fabrics, etc.
