Abstract:
1. A method for the production of a laminate material for hook and loop closures, comprising the following steps: laminating a textile material onto a carrier film via an adhesive, continuously passing the laminate material to a brush arrangement without winding the laminate material onto a take-up roll; brushing the textile material after said step of laminating; wherein the adhesive is applied to the carrier film in a pattern that has fields having adhesive areas and regions that are free of adhesive, and having field frames comprising an adhesive film applied over an entire area, and forming separate pieces from the laminate material, wherein the field frames are disposed in such a manner that the textile material and the carrier film have a complete surrounding glue connection at edges of the pieces obtained from the laminate material, said pieces forming female parts of hook and loop closures, wherein the brushing step is accomplished by means of at least one brush roller, wherein a surface of the brush roller moves at a positive or negative relative speed with regard to a speed of the laminate material that passes underneath the brush roller wherein by means of the brushing step the textile material in the non-glued regions of the laminate material are affected and deflected resulting in an improvement of the hook and loop properties of the laminate material, whereby some yarns that comprise textile material are split into fibers.
