Abstract
A stitch-bonded tape or other directionally stabilized product wherein stitch-bonding is carried out by overstitching yarns stitched through a sheeting or other surface substrate in conjunction with the introduction of high tenacity lay-in yarn elements disposed longitudinally in the machine direction of formation to provide strength in the length direction. The overstitching yarns secure the lay-in yarns in place relative to the surface substrate. An adhesive or other coating is disposed in covering relation to the lay-in yarn elements.
Claims21
A directionally stabilized composite of stitch-bonded construction having a machine direction and a cross-machine direction, the stabilized composite comprising:
- at least a first stitching substrate material;
- a plurality of elongated lay-in yarn elements disposed in substantially parallel relation to one another in the machine direction of the stabilized composite in overlying, juxtaposed relation to the first stitching substrate material;
- a plurality of stitching yarns stitched through the stitching substrate material in a zig-zag pattern defining yarn segments in overlying, crossing relation to the lay-in yarn elements such that the stitching yarns secure the lay-in yarn elements in place relative to the first stitching substrate material, the stitching yarns defining a plurality of stitches across a surface of the first stitching substrate material facing away from the lay-in yarn elements;
- and
- a coating disposed in covering relation to the lay-in yarn elements.
