Abstract
The invention discloses a filter screen and a manufacturing method of the filter screen. Curly vegetable fibers are main raw materials of the filter screen. The manufacturing method of the filter screen comprises the following steps: S10: the vegetable fibers are combed to be loose; S20: the vegetable fibers are paved into the preset thickness; and S30: the filter screen is manufactured through multitrace needling type seizing by the way of alternately needling from top to bottom and needling from bottom to top or the way of alternately needling from bottom to top and needling from top to bottom. Compared with a traditional plastic filter screen used for an air-condition, the filter screen has the advantages of being low in production cost, easy to degrade, free from polluting the environment, environment friendly, even in density and good in screening effect.
Description
