ABSTRACT:
For manufacturing filter material, a non-woven filter web is formed from electrostatically charged dielectric fibers. In order to give dimensional stability to the filter material without adversely affecting the permeability of the filter material, filaments or narrow strips are placed essentially at a distance from each other on at least one of the two sides of the filter web and fixed to the non-woven filter web.
