Abstract:
A method for hydraulically treating a web of fabric so as to impart to one side of the fabric a desired degree of hydroenhancement which comprises:(a) providing a curved fabric support member having at least one axis of curvature;(b) supporting the fabric on the fabric support member;(c) impinging an array of jet streams onto a surface of the fabric, where the jet streams emanate from a manifold having an array of jet orifices, the individual jet streams travel in substantially parallel paths, the paths of the individual jet streams are not directed toward a center of curvature of the fabric support member, and the jet streams impinge the surface of the fabric at a non-normal angle; and(d) moving the web of fabric in a direction that is perpendicular to the axis of curvature of the fabric support member.
