Publication number: 20010054209Abstract: A method for dyeing cellulosic materials with reactive dye by pretreating the fabric with a polycationic polymeric agent which is desirably also polynucleophilic is disclosed. The agent can be a polyquaternary amine material especially a poly(DADMAC) or polyvinylpyridine, particularly one including nucleophilic sites such as primary amino groups, e.g. polyallylamine/DADMAC copolymers and polyvinylpyridines quaternisied with w-aminoalkyl groups. The dyes can react with the nucleophilic centres so dyebath exhaustion can be driven by dye fixation rather than substantivity to the substrate. The need to use of salts to drive substantivity can be obviated and post dyeing washing to remove unreacted/hydrolysed dye is much simplified. Material dyed by the method has the good wash fastness properties of materials dyed using reactive dyes. A wide variety of cellulosic substrates can be dyed including lyocell fibre materials and blend/union materials with polyamides.Type: ApplicationFiled: August 23, 1999Publication date: December 27, 2001Inventors: GEOFFREY WILLIAM COLLINS, STEPHEN MARTIN BURKINSHAW, ROY GORDON

Patent number: 5695375Abstract: Novel regenerated cellulose fiber dyeable with disperse dye is disclosed. In this regenerated cellulose fiber, 10 to 40 weight % of polyester fine particles or styrene-acrylic polymer fine particles having an average particle size of 0.05 to 5 .mu.m are compounded. Products wherein the regenerated cellulose fiber and polyester fiber are used in combination can give dyed products excellent in homochromatic properties, and since both fibers can be dyed at the same time, the dyeing efficiency is remarkably improved.Type: GrantFiled: December 20, 1996Date of Patent: December 9, 1997Assignee: Kuraray Co., Ltd.Inventors: Osamu Takemura, Naoki Tanimoto, Eiji Iwasa, Ichirou Inoue, Tsutomu Kawamura, Kiyoshi Hirakawa, Shinichi Ono, Hitoshi Kimura, Mitutake Aruga
