Abstract

Improvements introduced in mud filters as a hose based on a synthetic fabric with warp threads that run vertically and weft threads that run horizontally as well as seams in the areas where the mud filter hangs and in the bottom part, characterized in that the weft thread adjustments of the fabric are denser in the area of the seams next to the hanging place and next to the bottom part than in the other parts of the fabric of the mud filter.
