A filter medium includes at least one filter membrane () having a fabric ply () as a supporting and protective layer. At least one additional filter membrane () with another fabric ply () as a supporting and protective layer is also provided. A third fabric ply () extends between both adjacent filter membranes (). Both adjacent filter membranes () are connected together by the threads () of the other two plies () which reach through to the third ply ().

Filter medium

A method for producing tubular membranes creates a very inexpensive production method, while obtaining very high output rates for tubular membranes. A tubular member () is formed from several threads () in such a way that at least some of the threads () are tightly tied together along web-type connecting lines () that are composed of longitudinal threads. At least some of the threads () form a transversal connection () between adjacent longitudinal threads () in between the web-type connecting lines (). A predefined membrane material () is applied to the tubular member ().
