    Abstract: A process for the drying and fixing by dry heat of basic dyes which have been padded onto fibrous material consisting of or containing acylonitrile polymers, wherein the thermal treatment is carried out in the presence of (a) a reaction product having a mean molecular weight of at least 200 obtained from an alkylene oxide and a compound which contains at least one hydrogen atom attached to nitrogen or oxygen and/or at least one carboxylic ester group and (b) either a compound having the general formula wherein R is a C6-C20 alkyl radical; R1 is H, methyl or ethyl; R2 is H, methyl or ethyl; X is 1 to 15, 2 is 0 or 1; A (when Z=0) is SO3H, or (when Z=1) is SO3H, PO4H2 or -(CH2)nSO3H and n is 1 to 3; or a water-soluble salt of said compound. The components (a) and (b) are each used in amounts of 50% to 500% with reference to the weight of the basic dye and the ratio (a): (b) is preferably 1:20 to 20:1. Component (b) preferably has a mean M.W. of 500 to 5000. Basic dyes used may be xanthenes, acridines, oxazines, diphenylmethanes, tri-phenylmethanes, anthraquinones, methines or azo type dyes. Compounds of type (a) above include adducts of ethylene oxide with castor oil, colophony, stearyl alcohol, oleylamine, oleyl monoethanolamide, propylene oxide and water, nonylphenol, sperm oil alcohol and ethylene glycol. Components (b) include alkyl benzene sulphonic acids; acid sulphuric acid or phosphoric acid esters of alkyl phenylglycols or polyglycols, alkylphenyl glycol or polyglycol sulphoalkyl ethers or their water-soluble alkali metal amine, ammonium or alkaline earth metal salts. Components (a) and (b) may be applied in aqueous solution by dipping or spraying before or after the dye has been applied. The thermal treatment is carried out first at 100 DEG to 150 DEG C and then at 190 DEG to 210 DEG C for 20 to 180 seconds. The padding liquors may contain disperse dyes in addition to basic dyes and components (a) and (b).
