PROCESS FOR THE PRODUCTION OF A FIBER MATERIAL AND PROCESS FOR THE DYEING OF THE MODIFIED FIBER MATERIAL WITH ANIONIC TEXTILE DYES |
摘要 |
Process for the production of a modified fiber material and process for the dyeing of the modified fiber material with anionic textile dyes. Fiber materials can be modified by applying heterocycloaliphatic compounds containing at least one primary, secondary or tertiary amino group or quarternary ammonium group, the hetero portion of which in the ring is a carbonic ester radical of the formula -O-CO-O- or a carbamic acid radical of the formula -O-CO-NH-, in aqueous alkaline solution by exposing the fiber material to these compounds at a temperature of between 60 and 230.degree.C. The characteristic of the modified fiber material is that it can be dyed with dye solutions of watersoluble, anionic textile dyes which are low in electrolytes or entirely free of electrolytes and/or are low in alkali or entirely free of alkali. The advantage of a dyeing process carried out in this manner, in particular for fiber-reactive dyes, is that fixation of the dyes under alkaline conditions is unnecessary.
