Process for improving the quality of the stained fibers, of regenerated cellulose mass, characterized in that 0.01 to 1% relative to the mass of viscose yarns in addition to finely divided pigment dyes are added to it. cellulose content of a compound of the general formula ** (See formula) ** in which X and Y, mean independent of each other, oxygen or sulfur and X, independent of the significance in the first link, in the links of the chain that follow each other. Z, means (independent of the significance in the first link, in the chain links that follow one another) oxygen, sulfur or a group (see formula), wherein R3 represents hydrogen, an alkyl or hydroxy alkyl or lower alkyl group, which may also contain ether oxygen atoms. Alkylene means (independently of one another) a bivalent aliphatic radical with 2 to 4 carbon atoms. R1 means a lower hydroxyalkyl group, which may also contain ether oxide atoms. R2 means, hydrogen, an alkyl or hydroxy lower alkyl group which may also contain ether oxide atoms. n means a positive index of whole numbers between 6 and 12. m means a positive index of integers between 1 and 5. p means a positive index of integers between 1 and 3, and q means a positive index of integers between 1 and 2.
