Polyester filter bag (PE filter bag) is made of polyester fiber filter cloth, pure fiber is manufactured by needle punching method, forming a three-dimensional, highly fluffy three-dimensional depth, tortuous filter layer. Its characteristic is that the fibrous structure is loose, which increases the capacity of impurities; the product is a compound interception mode, which effectively removes solid and soft particles, that is, larger particles and impurities are trapped on the surface of the fiber, while fine particles are It is captured in the deep layer of the filter material to ensure that it will not be damaged due to pressure increase during use, and has a high filtration efficiency.
