METHOD AND APPARATUS FOR PATTERNING SUBSTRATES

摘要

A method for altering the surface appearance or texture of a textile or other substrate comprises impinging the surface of the substrate (25) with a high velocity fluid jet (18) with water being a preferred fluid. The substrate is placed against a support (20), and a fluid stream having a peak dynamic pressure in excess of about 2068 kPa (300 p.s.i.g) is directed onto the fabric surface. Various means are adopted to interrupt and re-establish contact between the stream and the surface in accordance with pattern information.
