This type of Air filter skeleton non-woven material(support layer) has good stiffness and ultra-low wind resistance, and is suitable for composite base fabrics and liquid filtration of various filter materials. The filtration efficiency can reach G4, with large surface area, high stiffness, good air permeability and high dust holding capacity. The filter material with carbon cloth used in the air filtration industry has excellent carbon blocking effect. Wet process skeleton non-woven fabric can also be directly used at a single-layer discount for primary filtration. In addition, this product also custom-processes functional materials, such as flame retardant, antibacterial, and dyeing.
Advantages of PET nonwoven fabric :
(1) High air permeability and ultra-low wind resistance. After being compounded with melt-blown PP, it is proved that the filtration efficiency of the compounded product is increased by 10%, and the resistance is decreased by 20%. So that the purification equipment achieves the purpose of energy saving.
(2) Good stiffness. This performance determines that the product is extremely resistant to wind pressure after being densely folded, and will not be deformed even when a large amount of air passes through.
(3) High tensile strength. The composite material has higher tensile fracture performance, tear resistance and burst resistance than the woven skeleton material before composite, so it can greatly improve the service life of the product.
