Abstract
A process for dyeing textile fiber materials with water-soluble dyestuffs, in particular anionic dyestuffs, and of these in particular those having a fiber-reactive group, in which the dyeing is carried out using low-electrolyte or entirely electrolyte-free and/or low-alkali or entirely alkali-free dye liquors or printing pastes and a fiber material which has been modified with a silane compound containing amino groups is used as the textile material. The fiber material is modified by applying the silane compound containing amino groups to the material in aqueous solution and subjecting the impregnated material to a heat treatment. Novel silane compounds which contain a secondary amino group and can likewise be employed for the purpose mentioned are furthermore described.
