  • Publication number: 20010054209
    Abstract: 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.

  • Patent number: 5484457
    Abstract: Process for the continuous production of surface dyeings on cellulose fiber textile materials, characterized in that the textile materials are treated with an aqueous liquor containing at least 5 g/l of benzyl halide quaternized condensation products of precondensates of trialkanolamines and ureas, cyclic carbonates and/or epihalohydrins and/or benzyl chloride quaternized condensation products of piperazine and epichloronydrin, and 0.02 to 1 g/l of a phosphoric triester whose alcohol component has 6 to 18 carbon atoms, the textile materials thus treated are then dyed in another bath with reactive dyes in an aqueous medium and the dyes are fixed by treatment with an alkaline aqueous liquor and the dyeing finished in conventional manner. The individual cellulose fibers of the textile material are not completely penetrated by the dye but, on the contrary, exhibit ring dyeing.

  • Patent number: 5417724
    Abstract: The cold water bleed propensity of acid and premetallized acid dyed cationic dyeable nylon fibers is substantially reduced by treating the fibers with both a nylon fixing agent and a cotton fixing agent. Colorfastness of acid and premetallized acid dyed nylon fibers, other than CD nylon fibers, is also enhanced by treating the fibers with both a cotton fixing agent and a nylon fixing agent.

  • Patent number: 5330540
    Abstract: As a means for applying a random mottled or hammered appearance to a textile material, this invention provides a process which comprises the steps of: (a) applying to the textile material an aqueous solution having a water insoluble dye dispersed therein and an ionic component in the form of a dispersant in sufficient quantities to disperse the dye; (b) subsequently applying to the textile material an aqueous flocculent solution including a counter-ionic component, thereby electro-chemically reacting with the ionic dispersant such that the dye is precipitated from solution in non-uniform concentrations; and (c) fixing the dye to the textile material, preferably by heat. A textile material dyed according to the process is also provided.

  • Patent number: 5298035
    Abstract: A process for preparing a thermosensitive fibrous structure which includes adding a fibrous substrate mainly composed of cellulosic fiber, microcapsules including a thermochromic material, a cationic surfactant and a nonionic surfactant to a dye bath maintained at a temperature of not higher than 90.degree. C. and then adding an agent for imparting exhaustion property in the bath at a pH not more than 7, thereby causing the fibrous substrate to exhaust the microcapsules from the bath. According to this process, there can be obtained a thermosensitive fibrous structure wherein microcapsules are almost completely exhausted and uniformly provided.
