Abstract
A woven fastener product includes an array of hook elements and an array of loop elements that extend from the surface of different respective regions of a common fabric base. The arrays are formed by warp yarns, the arrays being separated in the warp direction of the fabric base. To form a self-engaged fastening, the fastener product is conformed so that the hook elements overlie the loop elements. Monofilament loops are shown sized and located to provide pin-receiving mounting sleeves as part of the woven structure.
Claims32
A woven fastener product including a fabric base having ground yarns comprising warp yarns and filling yarns extending respectively in warp and filling directions, the woven fastener product, in the warp direction, having separate functional regions,
- the functional regions having respective fastener element arrays including a plurality of rows of fastener elements, the fastener elements comprising yarns of the fabric base that project from a surface of the fabric base in selected locations,
- a first functional region including a plurality of rows of loop-engaging fastener elements and being substantially free of loop fastener elements, and a second functional region including a plurality of rows of loop fastener elements and being substantially free of loop-engaging fastener elements.
A woven fastener product having monofilament warp yarns, at least some of the monofilament warp yarns in one region forming an array of hooks for hook and loop fastening, and in the warp direction, in another region at least some of the monofilament warp yarns forming loops that cooperate to form a mounting sleeve for a device to be attached to the fastener product.
