ABSTRACT:
A fabric includes an intermediate layer of substantially parallel spun warp yarns, the intermediate layer having a first surface and an opposite, second surface; a top backing layer formed of spun bonded non-woven fibers on the first surface of the intermediate layer; a bottom backing layer of spun bonded non-woven fibers on the opposite, second surface of the intermediate layer; a chain stitching extending substantially parallel to and between adjacent spun warp yarns to connect the top layer to the bottom layer and thereby secure the warp yarns therebetween; and the stitched fabric being hydraulically entangled to adhere the loose warp yarns to the spun bonded non-woven yarns of the top and bottom backing layers.
