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

Material dyed by the method has a “washed out” appearance similar to fabrics dyed using the “Jarofast” process, but the availability of a wide range of pre-metallized dyes gives a wider color range, and the method enables a wider range of substrates to be dyed successfully, including lyocell fiber materials e.g. those sold under Courtauld's trademark “Tencel” and blend/union materials with polyamides, easier processing and superior wash and light fastness.Type: GrantFiled: August 23, 1999Date of Patent: March 13, 2001Assignee: Imperial Chemical Industries PLCInventors: Geoffrey William Collins, Stephen Martin Burkinshaw, Roy Gordon

Patent number: 5630850Abstract: There is disclosed a process for printing fibre material by the direct printing process, which process comprises printing the fibre material with a print paste comprising at least one dye, one cellulose derivative or alginate as thickener as well as further customary assistants and wherein the print paste comprises .ltoreq.5% by weight, based on the print paste, of a homopolymer or copolymer based on acrylamide.The novel process makes it possible to obtain strong patterned prints on a white ground which have good levelness, good fastness properties and sharp contours. The print pastes are distinguished by good homogeneity, good storage stability and simple handling.Type: GrantFiled: May 31, 1996Date of Patent: May 20, 1997Assignee: Ciba-Geigy CorporationInventors: Paul Schafflutzel, Philippe Ouziel

Patent number: 5525125Abstract: A process for fixing dyes impregnated in fine-dimensional synthetic textile substrates in an environmentally safe manner. The process comprises contacting the dyed synthetic substrates with an aqueous solution of a phenol- and formaldehyde-free dye-fixative composition containing a copolymer ofa) 1.0 to about 20 percent by weight of vinyl sulfonic acid residues;b) 5 to 20 percent by weight of nonpolar or hydrophobic monomer residues; andc) 60 to about 94 percent by weight of hydrophilic ethylenically unsaturated carboxylic acid residues, the copolymers having a weight average molecular weight of from about 1,500 to about 15,000. The contacting step is for a time sufficient so that the dye-fixative composition is absorbed by the fabric.Type: GrantFiled: May 8, 1995Date of Patent: June 11, 1996Assignee: Henkel CorporationInventors: Arthur H. Cole, Susan C. Glenn, Grannis S. Johnson
