    摘要: Water-soluble polysaccharides which contain a) substituents selected from the group consisting of alkyl, hydroxyalkyl, carboxyalkyl and sulfoalkyl, b) N,N-disubstituted aminoalkyl groups, are prepared by alkylation of a polysaccharide in the presence of a base with one or more alkylation reagents, selected from the group consisting of compounds transferring alkyl groups, compounds transferring hydroxyalkyl groups, compounds transferring carboxyalkyl groups and compounds transferring sulfoalkyl groups, and also with an N,N-disubstituted amino-alkylsulfuric acid ester. The modified polysaccharides are used in paper production and waste-water purification and also in cosmetics.

    摘要: A process for printing and dyeing sheetlike fiber materials with anionic dyes comprisesa) first applying to the sheetlike fiber material an aqueous solution containing a fixing alkali and a compound which contains a primary, secondary or tertiary amino group or a quaternary ammonium group, which may each also be part of a heterocycle, by using a printing process, thenb) subjecting the sheetlike fiber material to a fixing treatment to modify the sheetlike fiber material, and finally and optionallyc) dyeing the modified sheetlike fiber material one or more times by a customary exhaust or padding method.
