Filter material for use in filter element for filtration of e.g. fuel, has supporting structures comprising electrically conductive structural elements formed by linear elements that run transverse or inclined to pleat folds of material

摘要

The material (1) has a multi-layer filtering medium (9) comprising a side at which fluid-transmissive inner and outer supporting structures (11, 13) laminarly rests, where the material passes around a support tube (5) in a pleat-like folded manner. The supporting structures have electrically conductive structural elements i.e. bicomponent fibers, formed by linear elements that run transverse or inclined to pleat folds of the material. The linear elements are metal-free, and the bicomponent fibers are formed from plastic threads coated with carbon.
