<p>An hydraulic treatment apparatus (10) and method is provided for finishing and upgrading the quality of filament cloth materials. The fabric (12) is supported on a member (52, 54) and impacted with a uniform, high density jet, fluid curtain (34, 70) under controlled process energies. Low pressure/low energy treatments spread filaments in the fabric to reduce air porosity and provide improved uniformity in material finish. High pressure and energy treatments increase fabric bulk and porosity. Fluid treated fabrics of the invention demonstrate substantial improvement in at least two of uniformity, cover, opacity, increased or decreased bulk, increased or decreased air permeability, abrasion resistance, tensile strength, edge fray, and seam slippage.</p> |
