Embodiment Construction
[0021] The present invention will be further described in detail below in conjunction with the embodiments, so that those skilled in the art can implement it with reference to the description.
[0022] This case provides a high-efficiency filter sheet for an air microfiltration membrane filter, which includes a polyvinyl chloride fiber layer and a polytetrafluoroethylene fiber layer, wherein the fiber filaments in the polyvinyl chloride fiber layer and the polytetrafluoroethylene fiber layer are respectively It is arranged in one direction, and the fiber filaments in the polyvinyl chloride fiber layer and the fiber filaments in the polytetrafluoroethylene fiber layer are at an angle of 60-65°C; research has found that after the two layers of fiber filaments are at a certain angle, The size of this angle can affect the wind resistance and filtering effect of the filter. Although it is more common to use two layers of fiber filaments perpendicular to each other in the prior art, ...
