polyester filter cloth has many excellent textile performance and wearability


Polyester filter cloth of a specific gravity of 1.38; melting point 255 ~ 260 ¡æ, bonding begins at 205 ¡æ, safe ironing temperature is 135¡æ; absorb humidity is very low, only 0.4%; filament breaking strength of 4.5 to 5.5 g / denier, short fibers of 3.5 to 5.5 g / denier; filament elongation at break of 15 to 25%, the short fiber is 25 to 40%; high-strength fiber strength of up to 7 to 8 grams / denier, elongation 7.5 to12.5%. polyester filter cloth has excellent wrinkle resistance, elasticity and dimensional stability, good electrical insulation properties, resistance to sunlight, abrasion, no mold and termite, has good resistance to chemical reagents performance, the ability of weak acid and weak base. At room temperature, a certain resistance to dilute acid capacity, resistance to strong alkaline poor. polyester filter cloth dyeing performance is poor, generally subject to high temperatures or with carriers in the presence of a disperse dye staining.
Action
1,    Improved high temperature stability, high temperature stability improved due monofilament polyester filter cloth three-dimensional distribution, while the asphalt has a strong adsorption, without winding, can absorb too much freedom asphalt, bitumen viscosity and the viscosity cohesion increases, while the criss-cross reinforcement and bridging effect, reducing the flow properties of asphalt, aggregates limiting lateral displacement or flow, effectively improved the temperature stability, the fibers to obtain the stability of asphalt concrete greatly improved.
2,       Improve the low temperature crack resistance, fiber adsorption of the asphalt, resulting in optimum asphalt content of asphalt concrete increases, the higher the asphalt content of the fiber asphalt mixture at low temperature of -40 ¡æ remains flexibility and high resistance tensile strength, resistance to shrinkage stress effectively, so that the mixture of low temperature cracking performance enhancements, reduce temperature shrinkage cracks and prevents the development of reflective cracking.
3, to improve the fatigue resistance of asphalt pavement under the action of the outside temperature environment, subjected to repeated wheel load effect, when the load repetition more than a certain number of times, the road surface under load stress generated within the structure will exceed the intensity decreased resistance, the pavement cracks, resulting in fatigue fracture failure, after mixing polyester filter cloth,monofilament uniformly distributed in the mixture of the reinforcement effect, it increases stiffness modulus, improved fatigue performance of asphalt concrete.
4, to improve water stability of asphalt pavement is water stability of asphalt pavement in the presence of water conditions, traffic loads and withstand repeated temperature sizing effect. adding polyester filter cloth, membrane thickening of asphalt, the water displacement reduction in the strength of asphalt, asphalt concrete and water penetration reduction in the amount of adsorption of the fiber plus the viscosity of the bitumen becomes large, increase of asphalt and Aggregate bond force, enhance asphalt mixture of asphalt and aggregate forming the interfacial film peeling role in the ability to resist moisture, thereby increasing the water stability of asphalt mixture.

polyester filter cloth/ clean cloth
polyester filter cloth has many excellent textile performance and wearability, versatility, can be pure textile manufacturing, also with cotton, wool, silk, linen and other natural fibers and other chemical fiber blended to produce color range, solid Tinggua , washable and easy to dry, iron and wash and wear good performance of wool, cotton, imitation, imitation silk, linen fabrics . polyester filter cloth fabric for shirts and blouses, coats, children′s clothing, upholstery fabrics and carpets and so on. Since polyester filter cloth has good flexibility and fluffy, but also can be used as floss. Industrially high strength polyester filter cloth can be used as tire cord, conveyor belts, fire hoses, ropes , fishing nets, etc., can be used as an electrically insulating material, acid over polyester filter cloth and paper blankets. Polyeste r filter clothmade with non-woven fabric can be used for interior decoration, carpet backing cloth, medicine industrial fabrics, wadding velvet lining.
