    摘要: A process to remove excess dye from dyed polyester fabric comprising adding a solution of a weak organic acid to the fabric in a dyeing vessel, raising the temperature in the vessel to at least 80° C., allowing the acid to react with the fabric for at least 6 minutes and removing all liquid.

    摘要: Micro-particles of transition metals or their compounds can be generated as an integral part of a fiber by first attaching a nucleating agent to the fiber, and then adding a solution of metal ions. The ions are reduced by the nucleating agent in the fiber, and micro-particles are generated in or on the fiber. Because of the strong color signal resulting from a low concentration of metal micro-particles, the method is cost effective even when using gold or titanium ions. Various colors were generated by changing the size and spacing of the micro-particles, the metal or metal complex used, and the characteristics of the fiber. The dyed fibers displayed colors ranging from pink, red, purple, yellow, orange, peach, brown, gold, silver, grey, green, and black. These colors resisted bleaching by either chemicals or light.

    摘要: An immersion method of dyeing textile material includes the steps of (a) providing a textile material comprising at least one of cotton and regenerated cellulosic fibers; (b) providing an aqueous dyebath in a weight ratio of dyebath:textile material of 10:1 to 20:1, the dyebath comprising a reactive dye and a carboxylate salt for salting out the dye onto the textile material, the carboxylate salt having a carboxylate anionic component and a monovalent cationic component, wherein the carboxylate salt is present in an amount effective for salting out the dye onto the textile material; (c) immersing the textile material in the aqueous dyebath under conditions sufficient to salt the dye onto the textile material; (d) adding to the dyebath an alkaline material to promote a reaction to form a chemical bond between the dye and the textile material; and (e) subjecting the dyebath containing the textile material and the alkaline material to conditions sufficient to form a chemical bond between the dye and the textile material.
