Abstract:
1. A multi-layer sheet material adapted to be used as a portion of a tear away fastening system, said sheet material comprising: a substrate layer; and a plurality of loop forming yarns extending through said substrate layer such that said loop forming yarns define a plurality of loop elements projecting away from said substrate layer and wherein said loop elements are interconnected by portions of said loop forming yarns defining intermediate yarn segments disposed across a face of said substrate layer projecting away from said loop elements, wherein the intermediate yarn segments are substantially free of interlocking relation to other yarn segments disposed across said face of said substrate layer projecting away from said loop elements and wherein said loop elements are arranged in a discontinuous pattern along substantially parallel rows of needle punctures such that the loop forming yarns extend across the substrate layer through a first portion of said needle punctures and such that a second portion of said needle punctures devoid of loop forming yarns is disposed in a predefined pattern to occupy positions between at least a portion of said loop elements along said parallel rows of needle punctures whereby the number of said loop elements is less than the total number of needle punctures along said parallel rows of needle punctures; and a backing layer disposed in substantially fixed relation to said face of said substrate layer projecting away from said loop elements to hold the intermediate yarn segments in place.
