Abstract
A laminate material for hook-and-loop closures, comprising a carrier film and a textile substrate laminated onto the carrier film. The textile substrate has loops on its surface that are suitable for connecting with hook-and-loop hooks, wherein the carrier film and the textile substrate are not connected over their entire area. A method for producing a laminate material for hook-and-loop closures comprises applying an adhesive to a carrier film in a pattern that is composed of adhesive areas and adhesive-free regions, applying a material web of a textile substrate to the side of the carrier film provided with adhesive to form a two-ply web, the textile substrate having loops on its surface that are suitable for connecting with hook-and-loop hooks; and passing the two-ply web through a roller nip of a pair of rollers, which presses the carrier film and the textile substrate together.
