| titleOfInvention | Improvements in dyeing nitrogenous fibres |
| abstract | In the dyeing or printing of nitrogenous fibres by the process of the parent Specification, wherein the fibres are treated with an aqueous bath or paste containing a 1 : 2-chromium or -cobalt complex compound of an azo dyestuff, the complex containing at least two acid solubilising groups, together with a compound containing at least one basic nitrogen atom to which is bound a residue containing a polyglycol ether chain, improved results are obtained by also incorporating in the bath or paste an organic, non-ionisable, hydrophilic compound that is at most restrictedly soluble in water such as benzyl alcohol, b -phenoxyethyl alcohol, geraniol, cyclohexanol, n-butanol, amyl alcohol, n-hexanol, 2-ethyl-hexanol and n-octanol. Dyeing is effected from an acid bath at a temperature not exceeding 80 DEG C. The fastness of the dyeings is improved by adding an alkaline substance, such as ammonia, hexamethylene tetramine, sodium bicarbonate or triethanolamine, to the bath after the fibres have absorbed the desired amount of dyestuff. One example describes slubbing printing on woollen tops, the paste containing besides the dyestuff and tragacanth thickening, the reaction product of ethylene oxide and oleylamine, together with benzyl alcohol, urea and acetic acid. |
