We all know that polypropylene filament with "D \ F" to express, are generally 24F, 36F is a simple point of silk is divided into 24 and 36 monofilament is like a fishing line is a single.

Polypropylene filament and polypropylene monofilament are the classification of polypropylene yarn, in fact, literally can be seen on the difference, polypropylene filament yarn is a joint, such as 2 shares, 3 shares, etc., and polypropylene monofilament that white filament Are single.

Made of polypropylene filament floc, light, warm, good elasticity. The polypropylene monofilament also has the thickness of the points, the thicker polypropylene monofilament can be made of fishing nets and various types of ropes, smaller polypropylene monofilament can be made into artificial bristles, finer monofilament can be processed into elastic yarn, socks, elastic Clothing, etc., made of monofilament made of textiles thin, transparent and feel better. The use of polypropylene filament is mainly the production of carpets, a variety of ropes, fishing nets and other industrial aspects, in addition to the application of the other aspects of clothing is also widely used with a variety of fiber blended into different types of blended fabric, after knitting can be made Warm clothing, sportswear, socks and so on.

The physical properties of polypropylene filaments, let's take a look.

1. The longitudinal surface of the polypropylene filament is smooth and smooth.

2. The highest advantage of density polypropylene filament is the texture of light, its density is only 0.91g / cm3 is the most common chemical fiber in the lightest varieties, so the same weight of polypropylene than other fibers can be higher coverage area.

3. Strong stretch of polypropylene filament strength, elongation, the initial modulus is higher, excellent flexibility. So good wear resistance of polypropylene. In addition, the wet strength of polypropylene filament is basically equal to dry strong, so it is the ideal material for making fishing nets and cables.

4. Hygroscopic and dyeing properties of light warm and good; almost no moisture, but the wicking ability is very strong, moisture perspiration obvious; polypropylene hygroscopicity is very small, almost no moisture, the general conditions of moisture regain near zero. But it has wicking action, through the fabric of the capillary to pass water vapor, but it can not afford any absorption. Polypropylene filament dyeing is poor, incomplete chromatography, but you can use the liquid method to compensate for the lack of liquid.

5. Acid and alkali resistant polypropylene filament has good chemical resistance. In addition to concentrated nitric acid and concentrated caustic soda, polypropylene filament has good resistance to acid and alkali, so it is suitable for use as filter material and packaging material.

6. As the polypropylene filament thermal conductivity is small, good warmth.

7. High strength polypropylene fiber filament strength after the nylon, but the price is only nylon 1/3; made fabric size stability, wear elasticity is also good, good chemical stability. But the thermal stability is poor, intolerant to the sun, easy to aging fragile, this is often added in the anti-aging agent in polypropylene.
