Polypropylene filament fastness and wear fastness is good, shrinkage rate is small, easy to wash and dry, dimensional stability is good, relatively crisp. However, the heat resistance is poor, should not be ironing, if you want to ironing, the temperature should not exceed 100 ° C, can not be soaked in boiling water, should be washed with cold water or low temperature water, it is poor light resistance, can not be exposed to the sun. There is a stuffy feeling when wearing, poor dyeing performance and so on.


The physical properties of polypropylene filament, let's understand together.

one The vertical surface of the polypropylene fiber is straight and smooth, and the cross-section is circular.

2. The advantage of density polypropylene filament is that it is light in texture, and its density is only 0.91g/cm3, which is the lighter variety of common chemical fibers, so the same weight polypropylene has a higher coverage area than other fibers.

3. The tensile polypropylene polypropylene filament has high strength, large elongation, high initial modulus and excellent elasticity. So polypropylene wear resistance is good. In addition, the wet strength of polypropylene filament is basically equal to the dry strength, so it is the ideal material for making fishing nets and cables.

4. Hygroscopicity and dyeability, light quality and good heat preservation; Almost no moisture absorption, but the core absorption ability is very strong, moisture absorption and sweating effect is obvious; The hygroscopic property of polypropylene is very small, almost non-hygroscopic, and the moisture regain rate under general atmospheric conditions is close to zero. However, it has a core suction effect, which can transfer water vapor through the capillary tubes in the fabric, but does not have any absorption effect itself. The chromatism of polypropylene fiber is poor and the chromatography is not complete, but the method of stock solution coloring can be used to make up for the deficiency.

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

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

Seven. High strength polypropylene general strength is second only to nylon, but the price is only 1/3 of nylon; The size of the fabric is stable, the wear resistance and elasticity are good, and the chemical stability is good. However, the thermal stability is poor, not resistant to sunlight, easy to aging brittle damage, for which anti-aging agents are often added to polypropylene.
