Apparatus to create an improved moire fabric

摘要

An apparatus and method for creation of moiré fabric. This can be achieved by placing a first piece of fabric against a support member and directing at least one stream of fluid at the surface of said first piece of fabric to provide lateral yarn displacement. Then delivering said stream at a peak dynamic pressure in excess of about 300 p.s.i.g. and less than 4,000 p.s.i.g. and selectively interrupting and re-establishing contact between said stream and said surface in accordance with pattern information in order to pattern said first piece of fabric. This is followed by combining said patterned first piece of fabric with an unpatterned second piece of fabric in overlapping relationship and applying pressure by means of calender rolls having smooth surfaces to said combination of said first piece of patterned fabric and said second piece of unpatterned fabric.
