PROBLEM TO BE SOLVED: To avoid the problems on environmental hygiene by using a specific carbohydrate as an auxiliary in the substitution of urea for dyeing and printing fiber materials. SOLUTION: A compound represented by the formula: Z-G-T-R'n [Z is a residual group of a saccharide selected from monosaccharides, disaccharides, oligosaccharides or sugar alcohols, preferably residues represented by formulas I-III (R<2> is hydroxymethyl, carboxyl, acetyl or a 1-4C alkoxymethyl; R<3> is H, sulfo, acetyl or a 1-4C alkylsulfonyl or the like; R<4> is H, acetyl, benzoyl or the like, x is a number of 1-20); G is a bridging factor selected from the group consisting of O, NR<5> , OCO, NR<5> CO and NR<5> SO2 where R<5> may be substituted with 1-4 residues selected from H, OH, sulfo or the like; T is a 4-30C aliphatic, alicyclic or olefinic hydrocarbon and n is 0-3] is used as an auxiliary for dyeing, for example, pad dyeing, one-step printing, discharge printing, ink-jet printing. |
