A dryer filtration fabric for use in a drying section of a machine for producing and/or processing a fibrous web, in particular paper, cardboard, tissue or non-woven, has machine direction threads interwoven with machine cross direction threads to form a single-ply woven fabric having an air permeability between 40 cfm and 330 cfm. The machine direction threads and the machine cross direction threads have a flattened cross-sectional shape with a width-to-height ratio of more than 1. Each of the machine direction threads runs over and/or under a maximum of three, preferably a maximum of two, machine cross direction threads that are disposed directly beside one another. The number of the machine direction threads per 10 cm, viewed in the machine cross direction, lies in the range from 170 to 200, and the filling level of the machine direction threads lies in the range from 90% to 110%.
