    摘要： The present invention relates to a filter medium, a method for the manufacture thereof and the use of the filter medium according to the invention.
    The filter medium according to the invention comprises at least two textile nonwoven layers which are joined to one another by needling. The needled composite is then subjected to an aftertreatment so that the holes present from the needling are reduced by at least 50%.
