Abstract: A method for modifying fabrics to produce varied effects comprises projecting a stream of particles towards the fabric surface. The particles are projected under controlled conditions such that they contact the surface with a force effective to modify the fabric and change the feel, appearance or material constitution of the fabric. Among the effects obtained are softening, worn or laundered appearance, design, pattern, picture, printing, textured or sculptured effects. The apparatus comprises a supply of a length of fabric and means for moving the fabric along a horizontal path. Located on the path is a support backing such as a flat plate, and means for slidably pressing the fabric against the support backing. Opposite to the support backing and facing the fabric surface is a treatment station which includes means for propelling a stream of particles towards the fabric surface.
