Changzhou leade new Mstar Technology Ltd is a professional polyester fiber, polyester fiber, in the article we know the price of polypropylene fiber, today we explain the performance characteristics of polypropylene fiber polypropylene fiber and polyester fiber are different;
A lightweight polypropylene fiber density is 0.90-0.92 g/cm3, in all the chemical fiber is the lightest, than nylon 20% lighter than 30% lighter than polyester, viscose fiber, light 40%, so it is suitable for winter clothing wadding packing or ski suit, mountaineering fabric etc..
Two: high strength, good elasticity, abrasion resistance, corrosion resistance
High strength polypropylene (dry and wet under the same), is an ideal material for manufacturing, cable nets; wear resistance and good elasticity, strength is similar with polyester and nylon, the rebound rate comparable with nylon, wool, polyester and viscose fiber than the much larger size stability; polypropylene, pilling and deformation, anti microbial, not boring; chemical resistance is better than the general fiber.
Three: has electrical insulation and warmth
Polypropylene fiber with high resistivity (7 x 1019.Cm), small thermal conductivity, compared with other chemical fiber, polypropylene electrical insulation and heat preservation is best, but the processing is easy to produce static electricity.
Four: heat resistance and aging resistance performance is poor
The low melting point of polypropylene fiber (165~173 C), the stability of light and heat, so polypropylene heat resistance and resistance to aging poor, no ironing. But by adding anti ageing agent to improve its anti aging performance in spinning.
Five: the hygroscopicity and poor dyeability
Hygroscopicity and dyeing properties of polypropylene fiber is the worst in chemical fibers, almost no moisture absorption, the moisture regain is less than 0.03%. Fine denier polypropylene fiber has strong wicking effect, water vapor can be excluded by the capillary fiber. Made of clothing, clothing comfort is better, especially the superfine polypropylene fiber, because the surface area increases, can quickly transfer the sweat, make the skin feel comfortable. Due to the fiber moisture and small shrinkage, polypropylene fabric has the characteristics of easy washing drying.
The dyeing properties of polypropylene is poor, pale, poor color fastness. Ordinary fuel cannot make the dyeing, colored polypropylene is used most precoloration production. The dope dyed fiber modified polypropylene fiber, polypropylene fiber, characteristic of the fuel complexing agent in the melt spinning before mixing.

Polyester fiber, polyamide fiber, polyacrylonitrile fiber, polypropylene fiber and synthetic fiber is commonly used in life. A lot of people for polypropylene fiber and polyester fiber is not clear, today we're going to talk to you about the difference between polypropylene fiber and polyester fiber, mainly in two aspects:
A polyester fiber is polyester as the main raw material, add some functional masterbatch, the product density is 136g/cm3, soluble in phenol 14 chlorine ethane, o-chlorophenol as solvent, hygroscopic minimum, acid resistance, high chemical stability and polyamide, and have good light fastness. Polypropylene fiber is a high strength polypropylene monofilament fiber bundle, with addition of simple technology, low price and good performance. To effectively control the concrete or mortar concrete (mortar) micro cracks caused by solid plastic shrinkage, dry shrinkage, temperature changes and other factors, prevent and restrain the formation and development of cracks.
Two, polyester fiber reinforced asphalt concrete pavement for the general effect of the material is 100% modified polyester and polypropylene fiber concrete, as secondary reinforcement material, polypropylene material is 100%, mainly to improve anti cracking impermeability, impact resistance, earthquake resistance, anti freezing effect.
Above is the introduction of the "difference" of polypropylene fiber properties of polypropylene fiber and polyester fiber, if you want to know about Polyester And polypropylene fiber, prices and other information, we can focus on the latest information;
