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.

Abstract: Because the high dyeing temperatures employed necessitate the use of formaldehyde as customary wool-protecting agent and because of the resulting sealing problems on jet-dyeing machines, an HT dyeing of polyester fibre/wool blends cannot be carried out without polluting the environment. If, however, to achieve this purpose, lower temperatures are employed and the consequently required carriers are added directly to the dyeing liquor, this in turn gives rise to levelness problems and fastness reductions on the wool portion of the textile material.It has now been found according to the invention that by metering the carrier under isothermal conditions into the dyeing after 10-20 minutes via the gas stream driving the textile material it is possible to obtain a homogeneous distribution thereof and its full effectiveness without fastness losses. The dyeing can be completed 10-30 minutes later. All the advantages of jet dyeing are fully retained in this process.
