Abstract
A woven, self-engaging fastener with upright, mushroom-shaped, monofilament engaging elements that are in a thermally relaxed, stress-reduced condition. The engaging elements are arranged in a twill-like pattern such that weft-wise adjacent engaging elements are aligned diagonally to the weaving direction, and with sufficient density to enable the fastener to function as a self-engaging fastener. The fastener is produced by weaving a three-dimensional, double plush weave having two layers of interwoven warp and weft threads, and monofilament fibers interwoven with and passing back and forth between the two layers. The monofilament fibers are relaxed by heating, then severed between the two layers.
