Uniformly dyed water-swellable cellulosic fibers

Uniformly dyed water-swellable cellulosic fibers, said fibers being fast to washing, dry cleaning, sublimation and light and being produced by contacting water-swellable cellulosic fibers successively or simultaneously with water, ethylene glycol or a derivative of ethylene glycol and, while the fibers are still swollen, with an essentially water-insoluble dye of the formula ##STR174## in which D is phenyl substituted by fluorine, chlorine, bromine, methyl, trifluoromethyl, ethyl, methoxy, ethoxy, phenoxy, nitro, cyano, methylsulfonyl, ethylsulfonyl, phenylsulfonyl, alkoxycarbonyl or 1 to 8 carbon atoms acetylamino, benzoyl, carbamoyl or sulfamoyl which are N-substituted by alkyl of 1 to 8 carbon atoms, by phenyl of by phenyl which is substituted by chlorine, methyl or methoxy, oxdiazol-5-yl, 3-phenyloxdiazol-5-yl, 4-phenyloxdiazol-2-yl, phenylazo, phenylazo substituted by chlorine, bromine, nitro, methyl, ethyl, methoxy or ethoxy, CONH(CH.sub.2).sub.3 OC.sub.2 H.sub.4 OT.sup.1 or SO.sub.2 NH(CH.sub.2).sub.3 OC.sub.2 H.sub.4 OT.sup.1 ;

• ##STR175## where n is 0 or 1, T is C.sub.6 H.sub.5, C.sub.2 H.sub.4 C.sub.6 H.sub.5, (CH.sub.2).sub.3 OC.sub.2 H.sub.4 OC.sub.6 H.sub.5 or ##STR176## T.sup.1 is alkyl of 1 to 8 carbon atoms, benzyl, phenylethyl, cyclohexyl, phenyl or tolyl, T.sup.2 is methyl, chlorine or bromine, R is alkyl of 1 to 4 carbon atoms, phenyl or phenyl substituted by chlorine, bromine, methyl, methoxy or ethoxy, and R.sup.1 is phenyl, or phenyl substituted by chlorine, bromine, methyl, ethyl, methoxy, ethoxy, benzyloxy, phenoxy, chlorophenoxy, alkoxycarbonyl (where alkoxy is of 1 to 8 carbon atoms), cyano, phenylsulfonyl, CONHT.sup.3 or SO.sub.2 NHT.sup.3, or ##STR177## where T.sup.3 is alkyl of 1 to 8 carbon atoms, cyclohexyl, benzyl, phenylethyl, phenyl, phenyl substituted by chlorine, methyl, methoxy or ethoxy, or (CH.sub.2).sub.3 OC.sub.2 H.sub.4 OT.sup.1.
