    Abstract: To facilitate dyeing or printing cellulose derivative textiles with acid dyestuffs containing one sulphonic acid group and/or one sulphonamide group (see Group IV (c), there is incorporated in the spinning solution a compound of the formula in which X is CH2, CO or NH and R and R1 are hydrogen or alkyl, aminoalkyl or cyanoalkyl groups. Numerous compounds are specified.ALSO:Textile materials containing organic derivatives of cellulose, e.g. cellulose acetate or ethyl cellulose, are dyed or printed with acid dyestuffs containing one sulphonic acid group and/or one sulphonamide group, there being incorporated in the material, before or during dyeing or printing, a colourless, water-insoluble, bicyclic, saturated basic compound of the formula in which X is CH2, CO or NH and R and R1 are hydrogen or alkyl, aminoalkyl or cyanoalkyl groups. The basic compound may be applied to the textile, before dyeing, as an aqueous dispersion or as an aqueous solution of its formaldehyde-bisulphite compound or its salt with an organic or inorganic acid. When the basic compound is added to the dyebath it may be necessary to add acid. Alternatively, the compound may be added to the spinning solution from which the textile fibres are spun. Numerous examples of compounds of the above formula are given. Specified suitable dyestuffs are of the anthraquinone and azo classes and also the condensation products of 4-amino-3-sulphonaphthalene-1 : 8-dicarboxylic acid anhydride and aromatic amines. Numerous examples are given, in one of which (example 4) acetate fabric is printed with the formaldehyde-bisulphite compound of the base, dried, steamed and then treated with the dyestuff to yield a printed fabric, and in another, (Example 5) the formaldehyde-bisulphite compound is added to the dyestuff printing paste. In examples 6 and 7 the basic compound is added to a cellulose actetate spinning solution employing acetone as the solvent.

    Abstract: Linear polyamide fibres, films and other shaped articles are dyed or printed with a dyestuff containing the anion of the formula: in which R represents an alkyl radical (branched or unbranched) containing 7-12 carbon atoms. The dyestuff cation may be a hydrogen, sodium, potassium or ammonium ion or that of an aliphatic, cycloaliphatic, aromatic or heterocyclic amine or that of a quaternary ammonium compound derived from such an amine. The dyestuff is applied from aqueous solutions or dispersions containing, if desired, anionic and non-ionic dispersing agents and thickeners. Dyeing may be effected at temperatures of 60 DEG -120 DEG C., from a bath of pH 3-10, advantageously an initially alkaline bath rendered acid during the final phase of dyeing, or alternatively the dye liquor may be padded on the fibres which are subsequently steamed. The printing pastes may contain the usual auxiliaries, several of which are specified. Examples of dyeing and printing are given. The dyestuffs are prepared by reacting primary alkylamines containing 7-12 carbon atoms with 1-amino-4-haloanthraquinone- 2-sulphonic acids, or with 1-amino- 2:4-dihaloanthraquinones in which latter case the halogen in the 2-position of the product is converted into a sulphonic acid group by reaction with sulphurous acid or a sulphite.
