The development of production and application of polypropylene fiber in domestic market

2014-11-27 Hits:670
Polypropylene is the abbreviation of polypropylene fiber, with isotactic polypropylene as raw material made of synthetic fiber, textile fiber in the smallest proportion, can float in the water on the fiber. The fiber can be spinning pure or blended with cotton, wool and other fibers made of fabric clothing, curtains, furniture, fabrics, you can also do socks, industrial filter cloth, insulating materials, non-woven fabric and so on. According to the forecast of the foreign consulting companies, polypropylene fibers in the world between 2000-2010 consumer demand annual growth rate was 3.8%, our country is 6.8%, higher than the world annual demand growth rate of 3.0 percent. In recent years, the domestic and foreign markets have a rising trend of polypropylene demand of high tenacity, high tenacity polypropylene fibre (commonly known as: polypropylene filament, polypropylene filament, polypropylene filament, industrial strength PP yarn, polypropylene filament, industrial polypropylene filament) due to its advantages of anti-aging, acid and alkali resistance, wear resistance, light weight, low thermal conductivity, seawater corrosion resistance and moisture, fracture strength, is widely applied in the safety belt, industrial tape, flexible bag, geotextile, industrial filter cloth, rope, cable, high-pressure fire hose, PVC reinforced pipe, conveyor belt, industrial sewing thread, canvas, plastic woven bag, polypropylene fiber crack and other fields, is a new ideal material instead of chemical fiber polyester and polyamide and polyethylene.
A rough classification, polypropylene fiber
1 polypropylene staple fiber
(1) and cotton blended, do fine linen, sheets, gloves, pants
(2) blended with viscose fiber can be used as a blanket
(3) PP carpet, carpet
(4) PP cotton, is both light and warm
2 polypropylene filament
(1) the proportion of polypropylene is smaller than water, wear resistance, corrosion resistance, ropes, nets and other do
(2) can be used for industrial use, canvas hose, packing material, filter cloth and clothing
(3): Color Masterbatch colored fiber by melt spinning process, spinning colored polypropylene staple fiber, filament. The use of pure or blended to produce a variety of fabrics and decorative fabrics
The development history of two, polypropylene fiber
Since the end of the twentieth Century, the rapid development of polypropylene fiber industry, new products emerging, increasingly wide range of applications. Spinning process by the conventional spinning speed 1.0-2.0km/min, speed spinning 2.0-3.0km/min to high-speed spinning (3.0-4.5km/min) and super high speed spinning (6.0-12.0km/min) [1]. Appearance of fine denier or ultra fine silk and fine new varieties of non-woven polypropylene fiber, make the application more and more widely. In addition to the production of non-woven fabric used as industrial fabrics, and filter materials, geotextiles, agricultural cloth, covering materials, medical materials, sanitary materials, such as disposable materials is also widely used in polypropylene fiber.
The development of polypropylene fiber processing technology and new applications continue to emerge, the performance of polypropylene resin proposed higher requirements, also contributed to the polypropylene production manufacturers continue to develop production to adapt to all kinds of new technology requires special resin. A review of the historical development of polypropylene fiber. It is reported that polypropylene fiber in the 1960s began to enter the market, polypropylene flat yarn gradually replace jute sacks industry is the basic raw materials which become. Canada Cel-lanese developed short-range polypropylene spinning in 1962. Over the same period of bulked continuous filament (BCF) began for the carpet industry. At present, 90% of the world's Carpet cloth and 25% carpet veil is made of polypropylene fiber. Functional fiber in Japan and the United States as early as the United States and other fiber industry developed countries have paid attention to. And in the late 60s, 20th century, Japan increases of functional fiber, high performance fiber research into their work, and constantly launch new products, high technology, with an emphasis on the decorative and industrial use, textiles to broaden the application areas. At present, Japan's functional textiles accounted for 39% of the total textile, recently Japan Mitsubishi launched Mitsubishi Pylen environment-friendly type polypropylene fiber. As the polymerization spinning technology, polypropylene fiber has a coarse to fine and superfine development. In the 70s of the 20th century, the development of fine denier polypropylene fiber first in the United States, Italy, the Czech Republic and other countries rise; super fine denier polypropylene fiber polypropylene fiber to the new varieties of silk and fabric development of thin type, not only has the advantages of conventional polypropylene fiber proportion of light, warm protection is good, high strength, high corrosion resistance, etc., is also a combination of soft, guide wet and comfortable characteristics, the fine and ultra fine denier filament is making sportswear, underwear, an excellent material for high-grade clothes and filter medium, which have unique and excellent wearability. In the middle period of the eighties of the 20th century, concrete reinforced polypropylene fiber made progress, the sixth branch of the United States of America and Western Europe began for the construction industry. Since the 90s of the 20th century, with the performance of polypropylene continuous improvement, more diverse varieties of polypropylene fiber, American General Motor Company, Dow Chemical Company and Monsanto Company in the field occupies very important position. 28% of American textiles are functional textiles. The polypropylene fiber is one of the four major sources of raw materials of synthetic fiber, polypropylene fiber rich, simple manufacturing process, low cost. Due to its excellent performance, it has broad prospects in the application of clothing, decoration and industrial supplies, so the development of new products of polypropylene fiber is not the best. The PP antibacterial fiber developed by the United States has many functions, such as flame retardant, anti-static, anti fouling and so on. Western European countries on research and development of polypropylene fiber is active, has successfully developed a conductive polypropylene fiber, electric fiber fiber, biological absorption fiber degradation.
The development of polypropylene fiber in China started late, but rapid development. 80s of last century, the average annual growth rate of 36%, significantly higher than the growth rate of 12% of global polypropylene, is significantly higher than the growth rate of 16% of the domestic synthetic fiber. Twentieth Century 90
