    摘要： Method and apparatus for digital printing of textiles with application of immobilization compound on the textile prior to printing. The method comprises, finding failed printing nozzles; carrying out immobilization of the textile without using at least some of the nozzles neighboring a failed printing nozzle; and printing the textile. The immobilization generally prevents the printing ink from running, so leaving out immobilization around the failed nozzle allows ink to seep into the unprinted gap. The immobilization however also stabilizes the ink, so one embodiment keeps some of the neighboring nozzles on during the immobilization.

    摘要： A process is disclosed for treating textile materials with selected amine oxides in order to change the aesthetics and/or make the materials more receptive to dyes. In particular, the treatment cause cellulosic materials, to become more cationic and thus more receptive to anionic dyes with or without stiffening. In a preferred embodiment, the process of the present invention is directed to treating fabrics containing cottons fibres but will work to a useful extent on wool, nylon and polyester. The process is carried out by contacting said fibers or fabric with the selected amine oxide compositions. The amine oxide compositions can be padded onto the fabric or printed onto the fabric. If printed onto the fabric according to a particular design, the design then becomes visible on the fabric once dyed.

    摘要： The invention relates to a method for producing aqueous liquor dyeable modified polypropylene threads. The inventive method is characterised in that a CR polypropylene suitable for fibre formation is mixed with a reaction partner which can react with CR polypropylene and the mixture obtained is processed in an extrusion spinning facility to form a thread. Suitable reaction partners are difunctional carboxylic acids, corresponding carboxylic acid derivatives or master batches made of polypropylene and difunctional carboxylic acids or corresponding carboxylic acid derivatives. The polypropylene threads obtained can be knitted to form textile fabrics. The polypropylene threads and textile fabrics can be dyed with the usual dyestuffs according to a standard aqueous liquor extrusion process.

    摘要： Cellulosic materials are dyed with reactive dye by pretreating the fabric with a polycationic polymeric agent which is desirably also polynucleophilic. 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 quaternsied with omega -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.
