In order to prepare a solution of cellulose in N-methylmorpholine N-oxide and water which, compared with known solutions, has a higher water content at the given cellulose content, a mixture of the three components is subjected to shear rates of 400-3000 s<-1>, preferably 500-800 s<-1>. This process allows solutions to be prepared which satisfy the following conditions (ccell = proportion by weight of cellulose; <IMAGE> = proportion by weight of water): <IMAGE> |
