A method of producing needled, structured and patterned velour textile web of nonwoven fleeces and fibrous textile material, wherein at least one layer of textile fibers, particularly staple fibers, creating a pattern is applied to at least a part of an at least single-ply pre-needled support fleece web by at least one of the characteristics selected from the group comprising color, form, material, degree of fineness and orientation, and, finally, subjecting the web to an additional one-step or, if applicable, multi-step needling for the patterning or structuring, with the fibers applied to the support web being pushed through the web until they become visible on the lower side of the web, with the pile of the fibers coming to rest substantially in the plane of the lower surface of the web and wherein the web lies for processing during all steps on a brush belt with a homogeneous surface formed by the tips of the bristles of the brush belt.
A method of producing needled, structured and patterned velour textile web of nonwoven material, comprising applying at least one layer of textile fibers, to a pre-needled nonwoven fleece support web said web having an upper and a lower side, said textile fibers differing from the fibers of said support web by their color, form, material, degree of fineness, orientation or combination thereof, and, finally, subjecting said web to at least one additional needling step wherein the fibers applied to said support web are pushed through said web until they become visible on said lower side of said web and form a substantially upright pile in a plane of the lower side said support web being processed during said method on a brush belt having bristles forming a homogeneous surface comprising the tips of said bristles.
A method for producing a needled, structured and patterned velour textile web of at least partially nonwoven fleece, comprising:
