  • Fabric softening apparatus
    Patent number: 4837902
    Abstract: 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 an 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 flexibiity, drape and softness of the fabric.

  • Method and apparatus for interrupting fluid streams
    Patent number: 4828174
    Abstract: A method and apparatus for forming and selectively interrupting one or more fluid stream which is confined within an open channel. A transverse fluid stream is introduced into the channel at a point under the stream flowing within the channel. Introduction of the transverse stream at relatively low pressures is sufficient to cause the stream within the channel to leave the confines of the channel. If the channel is directed at a target, the method and apparatus will allow intermittent and selective interruption of a fluid stream flowing within the channel and directed at the target.

  • Process for pattern dyeing of textile materials
    Patent number: 4808191
    Abstract: A process is provided for the pattern dyeing of textile materials wherein dye migration may be inhibited by the in-situ formation of a coordination complex of metal-thickener-dye when the dye-thickener solution is applied to the textile material pretreated with an aqueous solution of a water soluble salt of the metal. The metal is selected from zirconium, hafnium or aluminum. The thickener may be a naturally derived aqueous system thickener, such as guar gum, xanthan gum or other water-soluble gum thickener or may be a synthetically derived aqueous system thickener, such as polyacrylics and polyacrylamides.
