With oil refining by-products propylene as raw material made of synthetic fiber and polypropylene fiber rules Chinese goods name. Also called the polypropylene fiber. The sources of the raw materials is rich, simple production technology, product prices than other synthetic fiber relatively cheap. The physical and mechanical properties of the fiber features are: high intensity (short fiber for 4 ~ 6 g/denier, filament for 5 ~ 8 g/denier), wet strength and dry strength basic same, a small proportion of the (0.91) and wear resistance and corrosion resistance. The world an annual production capacity of 1980 years of polypropylene fiber has more than 1 million tons. The variety of polypropylene fiber have filament (including not deformation filament and body of deformation filament), short fibers, his neck with silk, crack, hollow fiber membrane fiber, special fiber, all kinds of composite fiber and non-woven fabric. Main purpose is to make carpet (including carpet bottom cloth and suede), decorating, furniture cloth, all kinds of rope, strip, fishing nets, oil absorbent MATS, building materials, packaging materials and strengthen industrial fabric, such as the polyester mesh, such as cloth bag. In addition in the dress respect application has become more and more widely, but with a variety of fiber blended made for different types of blended fabric, after knitting processing can be made into shirt after, coat, sports, socks, etc. The pp hollow fiber to be made by the effect was, qualitative light, heat preservation, flexibility is good. Polypropylene fiber in macromolecular structure contains no on can and dye combined with chemical groups, so dyeing more difficult. Usually the melt coloring, will paint preparations and polypropylene polymers in screw extrusion machine evenly mixed, after melt spinning get colored fibers fastness is very high. Another way is with acrylic acid, acrylonitrile, vinyl pyridine and copolymerization or grafting polymerization, make polymer molecules into the combination of dyes can and polar groups, again with the conventional method directly dyeing. In the process of polypropylene fiber production often need to join various additives to improve moisturecontent, resistance to light sex and resistance to flammability. The scientific name of polypropylene fiber, nearly flame namely melt shrinkage, flammable, away from the fire burning slowly and take the black smoke, the flame yellow, blue bottom, send out a oil flavour, after burning for the hard round yellow brown dust particles, hand twist fragile. It is by the propylene polymerization as raw materials, the melt spinning fibre. Polypropylene fiber in 1957 the official start of the industrialized production, synthetic fiber is the young guns. Because of polypropylene fiber has simple production technology, product and low price, high strength, light density relative advantages, so polypropylene fiber is growing fast. At present the pp already is the fourth largest variety of synthetic fiber and chemical fiber is common in the light of the fiber. Polypropylene fiber production including short fibers, filament and crack membrane fiber etc. Polypropylene film is made of polypropylene fiber first film and then stretched thin, make it split into the original fine form of mesh made.

Civil purposes: can be pure spinning or and wool, cotton or sticky fiber blended mix knitted etc to produce all kinds of material. Can be used in all kinds of knitting socks, gloves, knitwear like the knitting garment, wash bowl cloth, mosquito nets cloth, warm and packing, diapers wet, etc.

Industrial purpose: carpet, fishing nets, canvas, hose, concrete strength materials, industrial fabric and nonwoven fabric, etc. If carpet, industrial polyester mesh, rope, fishing nets, building materials, enhanced oil absorption blanket and decorating cloth, etc. In addition, polypropylene film fiber can be used for packaging material.

The difference between the polyester mesh materials

 

Polypropylene fiber's main physical and chemical properties

1. The form of polypropylene fiber surface smooth flat vertical, section assumes the circular.

2. Density polypropylene biggest advantage is light texture, its density is only 0.91 g/cm3 is common chemical fiber medium density the lightest varieties, so the same weight of polypropylene fiber get higher than other of the coverage area.

3. Strong sex of the high strength out the pp, elongation, initial modulus is higher, excellent elasticity. So the pp wearability. In addition, the basic equal to the pp wet strong dry strength, so it is making fishing net, the cable materials ideal.

4. Hygroscopic and dyeing sexual light warmth retention property; Almost no moisture absorption, but heart suck ability, moisture absorption perspiration obviously; Polypropylene hygroscopicity of small, almost no moisture absorption, general atmospheric conditions of the moisture content close to zero. But it has a core suction effect, can through the fabric of the capillary transfer water vapor, but can't afford any absorption effect itself. Polypropylene fiber dyeing the gender is poorer, chromatography is not complete, but can be used to make up for the method of coloring stock insufficiency.

5. Acid and alkali resistance of polypropylene fiber has good corrosive, in addition to nitric acid, strong KeXingNa outside, polypropylene fiber to acid and alkali resistance performance is good, so suitable for used as the filter material and packing materials.

6. Light resistance of polypropylene fiber resistance to light the gender is poorer, thermal stability also is poorer, aging, not resistant to pressing. But when the spinning to provide China agent, to improve its anti-aging properties. In addition, polypropylene fiber of electrical insulation is good, but the process easy generation static.

7. High strength polypropylene stretch yarn strength after polyamide fiber, but the price is only 1/3 of polyamide; Made into fabric dimension stability, wear-resisting elastic is also good, chemistry stability is good. But the poor thermal stability, not resistant to the sun, easy to aging brittle loss, therefore often in polypropylene fiber with inhibitor.
