▎ 摘　　要

NOVELTY - The film has a first hollow fiber film connected with an outer end of a second hollow fiber film. A surface of the second hollow fiber film is formed with a transverse groove (1) and a longitudinal groove (2), where a width of the transverse groove is 5 mm to 6 mm and a width of the longitudinal groove is 1 mm to 2 mm. A tooth-shaped bump is fixed with an inner wall of the longitudinal groove, where the first and second hollow fiber films are made of polytetrafluoroethylene resin, extrusion aid, hydrophilic modified nano zinc oxide, nano graphene, aramid fiber and glass fiber. USE - Anti-pollution hollow fiber film. ADVANTAGE - The film adds hydrophilic modified nano zinc oxide and a molecular structure contains strong polar groups, enhances antibacterial property of the zinc oxide in an inner end of film hole, prevents bacteria dirt blocking the film hole passage through setting of the transverse groove and the longitudinal groove, increases roughness of the outer wall of the film wire, enhances anti-pollution performance of the wire so as to prevent phenomenon of falling film flux and extends service life of the hollow fiber film. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for an anti-pollution hollow fiber film preparation method. DESCRIPTION OF DRAWING(S) - The drawing shows a side perspective view of an anti-pollution hollow fiber. 1Transverse groove 2Longitudinal groove
