Предложен способ получения модифицированного волокна и способ его окрашивания анионными красителями, применяемыми в текстильной промышленности. Волокнистые материалы можно модифицировать при использовании гетеро-циклоалифатических соединений, содержащих по меньшей мере одну первичную, вторичную или третичную аминогруппу или четвертичную группу аммония, гетеро-часть которых в цикле представляет собой радикал эфира угольной кислоты формулы -O-CO-O- или радикал карбаминовой кислоты формулы -O-CO-NH-, в водном, щелочном растворе путем воздействия этих соединений на волокно при температуре от 60 до 230<198>С. Модифицированный материал отличается способностью окрашиваться объединенными электролитом или вообще безэлектролитными и объединенными щелочью или бесщелочными растворами красителей, приготовленных из водорастворимых, анионных красителей, применяемых в текстильной промышленности. Проводимый таким образом способ предназначен, в частности, для активных в отношении волокна красителей, и имеет то преимущество, что при этом нет необходимости проводить фиксирование красителя в щелочных условиях.A method for producing a modified fiber and a method for dyeing it with anionic dyes used in the textile industry have been proposed. Fibrous materials can be modified using heterocyclic aliphatic compounds containing at least one primary, secondary or tertiary amino group or quaternary ammonium group, the hetero-part of which in the cycle is a carbonic ester radical of the formula -O-CO-O- or a carbamine radical acids of formula -O-CO-NH-, in an aqueous, alkaline solution by exposing these compounds to a fiber at a temperature of from 60 to 230 <198> C. The modified material is distinguished by its ability to be dyed with a combined electrolyte or, in general, without electrolyte and combined alkali or alkali-free dye solutions prepared from water-soluble, anionic dyes used in the textile industry. The method carried out in this manner is intended, in particular, for fiber-active dyes, and has the advantage that it does not need to fix the dye under alkaline conditions.
