Patent number: 5490865Abstract: The present invention is a process for producing two-tone or multi-color effects on animal fibers and the products derived from these fibers. Pretreatment of the fibers to increase the affinity of the fiber relative to metallic salts or dyes for is accomplished by treatment with an ethanolamine solution containing varying amounts of mono-, di-, or triethanolamine. A mordant treatment with a metallic salt exposes the pretreated fibers to an aqueous solution of organic acids and a metallic salt mordant having affinity for the pretreated fiber. The two-tone or multi-colored effect is achieved by combining the treated fibers with untreated fiber and dyeing the fibers in a dyestuff having affinity for the treated fiber. The dyeing process may also include placing treated and untreated fibers in a dye bath containing dye stuffs that have affinity to treated fibers and dyestuffs that have an affinity to untreated fibers.Type: GrantFiled: July 25, 1994Date of Patent: February 13, 1996Inventor: Jurg P.

Patent number: 4680032Abstract: A single, uniform application of dye is employed to generate a pattern dyed substrate wherein the pattern and pattern-complementary areas are dyed by the same dye, but at different levels of fixation. Dye is uniformly applied to the substrate, and optionally dried, without fixation. Heat is applied to the substrate uniformly as well as selectively in a pattern configuration. The uniform heating serves to fix the dye in the pattern-complementary areas at a pre-determined level. Selective heating in pattern areas serves to fix the dye at a higher level of concentration in pattern areas than is found in the pattern-complementary areas, resulting in a multi-tone effect. Optionally, the heating in pattern areas may be sufficient to cause shrinkage or other thermally-induced physical modification to the substrate, in perfect registry with the pattern-dyed areas.Type: GrantFiled: October 24, 1985Date of Patent: July 14, 1987Assignee: Milliken Research CorporationInventor: Robert C.

Patent number: 4589884Abstract: A method is disclosed for heat treating textile substrates wherein a substrate may be dyed in pattern configuration and, optionally, thermally modified to produce visual surface effects in the pattern areas in perfect registry. Dye is applied to the textile substrate, and optionally dried, without being fixed. Heat is selectively applied in pattern configuration to the substrate. The heat is sufficient to fix the dye in pattern configuration, at a pre-determined level of fixation, and may also be sufficient to cause thermal shrinkage or other thermally-induced physical modification to the substrate, also in pattern configuration. Unfixed dye may then be removed, leaving a pattern-dyed substrate which, optionally, may have physically modified areas in perfect registry. A mixture of dyes having different fixation energy levels may be used for multiple color effects.Type: GrantFiled: April 10, 1985Date of Patent: May 20, 1986Assignee: Milliken Research CorporationInventor: Michael W.
