International Classification:

B29C 41/22

US Classification:

264494, 118 56

Abstract:

A solid imaging apparatus is provided that includes a replaceable cartridge containing a source of build material and an extendable and retractable flexible transport film for transporting the build material layer-by-layer from the cartridge to the surface of a build in an image plane. An operator using the device needs merely to remove a spent cartridge and replace it with a fresh cartridge to continue solid imaging virtually uninterrupted. The apparatus also includes the capability of withdrawing and inserting an imager without the operator having to perform a separate alignment step. A brush attached to the transport film and forming part of the cartridge provides for intra-layer removal of excess uncured build material. If desired, the apparatus can produce a fully reacted build. A high intensity UV source cures the build between layers. An injection molded build pad is designed to hold a build in an inverted position for improving the build. The invention also provides for tilting the build elevator to reduce air entrainment and for releasing the build from the image plane.

International Classification:

D06Q 102

US Classification:

81146

Abstract:

This invention provides a process for sculpturing pile fabrics which comprises: (a) selectively contacting the surface of a pile fabric corresponding to a pattern a fiber degrading composition, said composition comprising a fiber degrading agent in a concentration sufficient to reduce the tensile strength of the fibers of the pile, said fiber degrading agent being selected from a compound of the formula: ##STR1## wherein R and R' are each independently selected from a lower alkyl group having from one to about five carbon atoms, dyes are optionally selectively applied in pattern form and in register with the fiber degrading composition; (b) heating the pile fabric to temperatures above 180. degree. F. but below 250. degree. F. , more specifically, heating with atmospheric steam to degrade the selected fibers of the pile and to provide fixation of the dyes; (c) the fiber degrading agent neutralizing with a solution of a base selected as a hdyroxide, carbonate, or phosphate of group I and II metals; (d) washing the pile fabric with water, to remove any residual components of the fiber degrading composition from the pile fabric; (e) conventionally drying the pile fabric; and (f) removing said selected and degraded portion of the fibers of the pile by mechanical means to provide a sculptured pile fabric.

Assignee:

Milliken Research Corporation - Spartanburg SC

International Classification:

D06P 500

US Classification:

8478

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.

Richard V. Gregory - Anderson SC

Assignee:

Milliken Research Corporation - Spartanburg SC

International Classification:

B32B 300

US Classification:

428195

Abstract:

An electrically conductive textile fabric in which the electrical conductivity may be made to vary in a pattern configuration, and a method for manufacturing such fabric. A textile fabric is coated with an electrically conductive polymeric coating, and the coating is selectively removed in those areas in which a reduced electrical conductivity is desired. The removal may be achieved by means of high velocity water jets, sculpturing, or other means.
