[Volkswagen chemical fiber: what are the benefits of polypropylene filament?]
Polypropylene fiber is the product name of polypropylene, which is made from propylene by polymerization and melt spinning. The production of polypropylene, which officially began in 1957, is a rising star in synthetic fibers. Because of the simple production process of polypropylene, low price, high strength, relatively low density and other advantages, polypropylene develops rapidly. Currently, polypropylene is the fourth largest variety of synthetic fibers.
polypropylene
The main features
form
The longitudinal plane of the polypropylene is smooth and the section is round.
The density of
The biggest advantage of polypropylene is its light texture, which is only 0.91 g/cm3, which is the lightest variety of common chemical fiber, so the same weight of polypropylene is higher than that of other fibers.
Strong stretching
High strength, high elongation, high initial modulus and excellent elasticity. So polypropylene wear well. In addition, the wet strength of polypropylene is basically equal to dry, so it is the ideal material for making nets and cables.
Hygroscopicity and staining
The moisture absorption of polypropylene is very small, it is hardly wet, and the moisture regain in general atmospheric conditions is close to zero. But it has a wick, which passes through the capillary in the fabric, but can't absorb any of it. The chromaticity of polypropylene is poor, the chromatogram is not full, but can use the method that the liquid colorization is used to make up the deficiency.
Acid resistance
Polypropylene has good chemical resistance, and besides concentrated nitric acid and strong caustic soda, polypropylene is good for acid and alkali resistance, so it is suitable for filtering materials and packaging materials.
Light fastness
It has poor light resistance, poor thermal stability, easy aging and ironing. But the anti-aging properties can be improved by adding anti-aging agent to the spinning. In addition, the electric insulation of polypropylene is good, but easy to produce static electricity when processing.
