<p>This application relates to a non-woven fabric wherein the fibers of the fabric are bonded to each other and/or to another material in a plurality of equality spaced-apart spots, wherein the spots are the same size and are combined in a plurality of identical groups of not less than three nor more than five identical spots, each of said groups of spots being spaced apart from each other, and each of said spots within each group being positioned along a curbed or straight line wherein the projection of said line beyond the end-spots of said group positioned along said line intersects and adjacent line along which an adjacent group of spots is positioned, and wherein the ratio of the distance separating the spots within each group of spots to the distance from an end-spot in each group to the next adjacent line along which an adjacent group of spots is positioned, is about 0.5 to about 3.0. This arrangement permits optimum adhesion with other material or consolidation of the fabric itself and also provides directionally neutral flexibility.</p> |
