ABSTRACT OF THE DISCLOSURE An apparatus and method of treating fabric by directing low pressure air at near-sonic velocity between the fabric and a rigid plate tangentially in the warp direction of the fabric to cause the fabric to vibrate at extremely high rate. This high speed vibration causes sawtooth waves in the fabric to break fiber-to-fiber resin or finish bonds thereby decreasing the bending and shear stiffness to enhance the flexibility, drape and softness of the fabric.
