Polypropylene filter cloth is currently one of the most widely used filter cloth. Therefore, we need to have a comprehensive understanding of the raw materials in the polypropylene filter cloth, one of which will also help our team have a better market judgments, the trend of the industry more powerful grasp!
Because of the special texture of polypropylene, the density is only 0.91g / cm3, lighter than water, only 60% of cotton, the lightest fiber in synthetic fiber. The higher strength of the fibers is 35.2-52.8 cN / tex for staple fibers and 44-70.4 cN / tex for filaments, which is close to nylon and polyester, especially after soaking, the strength does not decrease.
Polypropylene uses: High strength (72.5-76.0 cN / tex) Polyester multifilament and bristles are ideal for making ropes, nets and cables; low strength (18-25 cN / tex) Ideal alternative materials; ordinary polypropylene fiber as taking, good warmth, good moisture permeability (moisture regain <0.03%), underwear wearing no cold, the disadvantage is poor dyeing, feel rough, waxy feeling.
Polypropylene can also produce carpets, decorative fabrics, furniture fabrics, tapes, absorbent linoleum, building enhancements, packaging materials and industrial filter cloth, sackcloth and so on. Most commonly used in polypropylene fiber bags for belt, ribbon, rope, decorative fabrics and industrial textiles.
Polypropylene fine denier (fineness less than 1.9dtex) soft, no significant waxy feeling. Polypropylene can be mixed with a variety of fibers made of different types of confusion is non-woven, after knitting can be made into shirts, outerwear, sportswear, socks and so on. Made of polypropylene fiber hollow fiber, light, warm, good elasticity.
Polypropylene blended fabric features: Polypropylene fabric blend fastness and abrasion fastness, shrinkage is small, washable quick-drying, dimensional stability, relatively stiff. However, heat resistance is poor, should not comfort hot, as to comfort hot, its temperature should not exceed 100 ℃, can not be soaked in boiling water, should be washed with cold water or low temperature, it is poor lightfastness, can not be exposed to the sun. Smell when wearing the feeling, poor staining and so on.
Polypropylene heat resistance, poor light resistance, after 6 months of sunlight exposure, the intensity decreased by 50%; PP dyeing performance is poor, the general dye is not easy to make it, and is currently limited to dyed light, medium color , Its color fastness is also poor.
Polypropylene hygroscopicity is very small, almost non-hygroscopic, so its shrinkage is very small. For disinfection gauze, with the advantages of non-stick wounds. Polypropylene has good chemical resistance, at room temperature on the concentrated sulfuric acid, hydrochloric acid, caustic soda are very stable.
Later, with the continuous development of geosynthetics, PP non-woven fabric to improve the anti-aging and in-depth exchanges with the international counterparts in the application began to recognize the PP geotextile in Alkali and alpine and other harsh environments, the dominant role, And began to accept this material.
In the field of geotechnical engineering, the understanding and application of geosynthetics in China started relatively late. At the initial stage of application, PP materials were considered to be poor in light resistance and anti-aging performance and should not be used in projects of a century. Therefore, in addition to being widely used in temporary flood relief work, Polypropylene woven bags outside, in many projects rarely used PP geotextiles.
