A batchwise process for dyeing hydrophobic fibres at 110.degree. C. to 135.degree. C. with a disperse dye in the presence of an adduct of an average of 1 to 4 molar proportions of ethylene oxide, propylene oxide or styrene oxide or a combination of these oxides with 1 molar proportion of a phenol compound having the formula ##STR1## in which n is a number from 1 to 4,

Process for the dyeing of hydrophobic fibres

A new non-foaming composition which is useful for a substantially crease-free dyeing of polyester fibers and comprises a dyeing assistant and a surface-active glyceride.

Composition for use in the dyeing of polyester fibers

A process for the colouration of polyacrylonitrile textile fibres, wherein said fibres are coloured by printing or pad-steaming with a cationic dye in the presence of a carrier consisting of least one compound having the formula ##EQU1## in which Y is an oxygen or sulphur atom and m is a number from 1 to 2, obtaining on said fibres a rapid fixation of the cationic dye and a high colour yield.

Process for the colouration of acrylic fibres

Process for the colouration of acid-modified synthetic textile fibres, particularly polyacrylonitrile fibres or basic dyeable polyester fibres, wherein said fibres are coloured with a cationic dye in the presence of a compound of the formula ##EQU1## wherein R is a chloro-substituted phenyl group, Z is hydrogen or methyl and n is an integer from 1 to 3, obtaining on said fibres a rapid fixation of the cationic dye and an outstanding colour yield.
