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.
1. A nonwoven fabric for exhaust-gas treatment, the nonwoven fabric comprising: a multiplicity of metallic filaments;said metallic filaments having at least two types of different contours for exhaust-gas treatment, said at least two types of different contours including one type in wire form and another type in chip form, said at least two types of different contours having characteristics of metallic filaments being generated by using different production methods; the different production methods being: separation from a metal block; andwire drawing; a...
