HOE 91/F 377K Abstract of the disclosure: Process for the preparation of a modified fiber material and process for the dyeing of the modified fiber material with anionic textile dyes A process for the dyeing of fiber materials with water soluble anionic dyes, in particular those having a fiber- reactive group, is described, according to which dyeing is carried out using low-electrolyte or entirely electrolyte-free and/or low-alkali or entirely alkali- free dye solutions (dye liquors, printing pastes) and in which a fiber material is used which was modified by means of a saturated straight-chain or branched aliphatic or cycloaliphatic compound which is unsubstituted or substituted by one or more hydroxy groups and contains at least one primary, secondary or tertiary amino group or quarternary ammonium group and at least one hydroly- zable ester group, it also being possible for the alipha- tic radical in this compound to be interrupted by one or more hetero groups. Modification of the fiber material is carried out such that the aliphatic compound mentioned which contains amino and ester groups is applied to the fiber material in aqueous solution and the impregnated material is subjected to a heat treatment. Furthermore, a few new aliphatic compounds containing amino and ester groups are described which can be used for the modifica- tion of the fiber material.
