ABSTRACT:
A method and apparatus for treatment of materials in order to modify the texture and appearance. This is created by application of one or more gas jets directed away from the interior curved surface of a cylinder, generating a vortex which rapidly and repeatedly cycles the substrate at low tension past the gas jets. The rapid vibrations generated in the substrate by the jets serve to break apart fiber to fiber bonds caused by finish and loosen up the structure of the yarns and that of the substrate. This creates a desired aged appearance as well as a very soft texture.
