Method for adapting a filter medium to predefinable parameters and preferably a filter medium produced according to said method

The invention relates to a method for adapting a filter medium to predefinable parameters, such as electrostatic charge, flow-rate behaviour, dynamic pressure behaviour or differential pressure behaviour, fraction filtration efficiency and preservation of a constant quantity and quality of fluid additives. Said method is characterised in that at least one of the aforementioned parameters is adapted by the targeted influencing of the surface energy of the filter medium (18). 本发明涉及种用于使过滤介质与可事先给定的参数如-充静电，-流动性质、动压头性质或压差性质，-分馏分离度，和-流体添加剂的恒定量维持和质量维持相匹配的方法，其特征在于：通过有针对性地影响过滤介质(18)的表面能来实施与所述参数中的至少个参数的匹配。
