A solution of cellulose is formed by moving a premix of a tertiary amine N-oxide, water and cellulose through a thin-film evaporator using a bladed rotor under treatment conditions which specify, inter alia, an area of heated surface (1 m2 to 125 m2), a blade speed (2.5 to 8 m/sec), a pressure (25 to 100 mb) and a temperature (90 DEG to 135 DEG C.).
