Abstract
A soot filter for Diesel engines has a housing (2), in which filter material (11) of mineral fibers or yarns is arranged on a support (7). To prevent the filter material from losing its three-dimensional structure necessary for the filtration in the event of yarn breakage, it is formed at least partly or completely of knitted fabric (12), which maintains its internal coherence in the vicinity of individual loops even in the event of yarn breakage because of the interlacing of the yarns in the adjacent loops.
