Abstract
A woven sheeting fabric is provided with a variety of unusual and visually appealing decorative patterned effects by forming in the fabric open, shear areas of various size and shape having an appearance contrasting with adjacent, substantially heavier areas. The fabric comprises warp and weft yarns of corespun construction interwoven with one another to form a substantially uniform woven fabric construction. Each of the corespun warp and weft yarns has a continuous multifilament core portion and a sheath portion formed of staple fibers helically wrapped about the core portion to substantially surround and encase the same. The portions of the corespun warp and weft yarns which extend throughout the sheer areas of the fabric have the multifilament core portions thereof exposed and are substantially devoid of sheath fibers and are thus smaller than adjacent portions of the yarns in the heavier areas of the fabric, and the sheer areas of the fabric are thus thinner than the adjacent heavier areas to provide further contrast with the heavier areas.
