ABSTRACT:
An efficient, economical, compact diesel particulate trap has a plurality of perforated hollow tubes, on each of which a heat-resistant yarn is helically cross-wound to provide a plurality of layers that function as a filtering element. The yarn, which preferably is a continuous-filament ceramic yarn, has a core from which filaments or fiber segments project outwardly and intermesh with fiber segments of laterally spaced cores to provide traps. The cores of yarn convolutions of at least one layer are laterally offset from the cores of convolutions of an adjacent layer to deflect into tortuous paths gases flowing generally radially through the filtering element.
