NONWOVEN FABRIC FOR EXHAUST-GAS TREATMENT, EXHAUST-GAS PURIFICATION DEVICE AND METHOD FOR PRODUCING A NONWOVEN FABRIC FOR EXHAUST-GAS TREATMENT

摘要

A nonwoven fabric for exhaust-gas treatment includes a multiplicity of metallic filaments having at least two types of different contours of the metallic filaments. An exhaust-gas purification device includes a channel structure through which exhaust gas can at least partially flow. The channel structure is made at least partially with such a nonwoven fabric. A method for producing a nonwoven fabric for exhaust-gas treatment is also provided.
