The polyester water- and oil-repellent needle punched filter felt is impregnated with a mixed working fluid prepared by reactive fluoride additives to achieve the purpose of water-repellent and oil-repellent. After the filter material is treated with water-repellent and oil-repellent agent, it can form a molecular barrier around the surface of the fiber, which can prevent the adhesion and penetration of water and various oil contaminants. It is also resistant to sticking and easy to peel. The filter cloth is used in occasions with high moisture content, especially suitable for filtration occasions in southern my country or in rainy areas and with high air humidity.
*The polyester can also be mixed with polypropylene, acrylic and other medium and low temperature materials for needle punching
