A fabric having at least one hydraulically napped surface comprised of tangled fibers is disclosed. Because the fiber tangles are created from intact, undamaged fibers, fabric strength is not adversely affected by treatment. In addition, laundering enhances entanglement and the aesthetic qualities attributed to this fabric property: surface texture (hand), resistance to pilling, drapeability, and the like. These subjective characteristics have been quantified using values from the Kawabata Evaluation System. A process for creating such fabrics has also been disclosed. The fabric passes through one or two treatment zones in which high pressure fluids (e.g., water) are directed at the fabric surface as the fabric moves away from a support member. In the case of dual treatment zones, a substantially lower pressure is used in the second treatment zone.
A process for forming a napped fabric wherein said fabric passes through a treatment zone in which a plurality of individual streams of high pressure fluid is directed onto said fabric, said process comprising the steps of (a) directing said fabric against a support member having a support surface as said fabric enters said treatment zone, (b) directing said fabric away from said support surface as said fabric moves through said treatment zone, and (c) directing said plurality of individual streams onto said fabric as said fabric is leaving said treatment zone and is moving away from said support surface, thereby forming on said fabric a napped surface, said surface being adjacent to said support surface.
A process for forming a napped surface on both a first and a second side of a woven fabric, said fabric being comprised of yarns containing staple fibers, said process comprising the steps of moving said fabric along a path in which said fabric passes through a first treatment zone wherein a plurality of individual streams of high pressure fluid is directed onto said first side of said fabric, whereby said fluid streams arrange said staple fibers to form a napped surface comprised of fiber tangles on said second side of said fabric, and then moving said fabric along said path wherein said fabric passes through a second treatment zone wherein a plurality of individual streams of high pressure fluid is directed onto said second side of said fabric, whereby said fluid streams partially redistribute said fiber tangles from said second side of said fabric to said first side of said fabric, wherein said fluid streams in said second treatment zone directed at said second side have a pressure that is substantially less than the pressure of said fluid streams in said first treatment zone directed at said first side.
