Zusammenfassung:Described herein is a method for producing a viscose solution including a step of adding alkyl polyglycoside (APG) prior to and/or during xanthation of alkali cellulose. When APG is added prior to or during xanthation of alkali cellulose, the reactivity between alkali cellulose and CS2 could be increased and the xanthation could be accelerated, as a result of which formation of agglomerates and/or lumps in the obtained viscose solution and then the obtained viscose fiber spun therefrom is significantly reduced, relative to the situation when conventional surfactants such as phenyl ethoxylate are added likewise. Also described herein is a viscose solution obtained by the foresaid method, and a method for producing viscose fiber with the foresaid viscose solution or including the foresaid method.
