Abstract

The invention relates to a filter bag, a method for producing a filter bag, and use. The filter bag (5) is made of a filter fabric and has a longitudinal, substantially tubular form. One end (7) of the bag is closed and the other end (6) is open. Furthermore, the filter fabric is treated with an anti-scaling material (15) partly or completely.
