摘要： Continuous dyeing of voluminous cellulose fabrics, according to a two-bath procedure and without intermediate drying, with azo dyes produced on the fiber by coupling of their formation components is effected by incorporation in a developing liquor with which the previously impregnated fabric is slop-padded, wet-in-wet, of a combination comprising homo- or copolymers of acrylic acid amide and a wetting agent into said developing liquor; the liquor uptake by the moist fiber material is increased and the penetration rate of this liquor during the coupling is incited in such a manner that textile articles which exhibit even, well penetrated dyeings are obtained.Dyeing of for example cord, velvet, terry or pile fabrics with azo developing dyes has become feasible only in accordance with this invention. The process may be carried out also in semicontinuous operation.

摘要： In the dyeing of cellulose knitted fabrics in hose form, according to a two-bath procedure, with azo dyes produced on the fiber by coupling of their formation components, it was hitherto impossible on an industrial scale to forward the developing liquor in a sufficiently rapid manner into the interior of the textile hose, after impregnation of said tubular goods in a winch beck using the exhaust technique. Dyestuff development without intermediate drying was impeded by the insufficient liquor uptake of the flattened textile material that had previously been impregnated on subsequent slop-padding wet-in-wet with the developing liquor.By incorporation of an auxiliaries' combination comprising homo- or copolymers of acrylic acid amide and a wetting agent in said developing liquor, the liquor uptake thereof by the moist fiber material is increased and the penetration rate of this liquor during the coupling is incited in such a manner that textile hoses which exhibit even, well penetrated dyeings are obtained.Dyeing of tubular knitted fabrics, especially in hose form, with azo developing dyes has become safe only in accordance with this invention.

摘要： Continuous dyeing of cellulose knitted fabrics in hose form, according to a two-bath procedure and without intermediate drying, with azo dyes produced on the fiber by coupling of their formation components could be realized hitherto on an industrial scale in exceptional cases only. For the most part this dyeing method failed generally due to the insufficient liquor uptake of the flattened textile material that had previously been impregnated, on subsequent slop-padding wet-in-wet with the developing liquor.By incorporation of a combination comprising homo- or copolymers of acrylic acid amide and a wetting agent into the impregnation bath and the developing liquor, the liquor uptake thereof by the moist fiber material, both in the course of the impregnation phase and once more in the slop-padding operation for developing the dyes too, is increased and the penetration rate of the liquor during the coupling is improved in such a manner that textile hoses which exhibit even, well penetrated dyeings are obtained.Dyeing of tubular knitted fabrics, especially in hose form, with azo developing dyes has become feasible only in accordance with this invention. The process may be carried out as well in semicontinuous operation.

摘要： A process for the pad-dyeing of textile webs, especially tubular knitted fabrics, which consist totally or partially of cellulose fibers, wherein the textile material is padded on a padder with an aqueous liquor of reactive dyestuffs, alkalis for their fixation and wetting agents, said liquor additionally containing polymers or copolymers of acrylic acid amide in aqueous solution, in order to avoid difficulties with regard to an even dye penetration and uniform squeezed edges, and the dyestuffs are fixed according to the cold-dwell dyeing process.
