    摘要: In a process for making solvent-spun cellulose fibre, cellulose is dissolved in aqueous N-methylmorpholine N-oxide to form a solution, said solution is passed through at least one pipe, the temperature in degrees Centigrade of said solution in the center of said pipe being controlled at 1000/(X+0.98.sqroot.D) and/or the temperature of said solution at the interior wall of said pipe being controlled at 1000/(Y+1.15.sqroot.D) where D represents the internal diameter of said pipe in inches, X represents a value equal to or greater than 5.0 and Y represents a value equal to or greater than 5.4, and said solution is subsequently extruded through a die to form filaments which are coagulated, washed with water to remove said solvent and then dried, thereby forming said solvent-spun cellulose fibre.

    摘要: A method is disclosed of forming a premix which is suitable for conversion into a cellulosic dope which can be used to produce cellulosic products. The method involves introducing into a mixing chamber predetermined quantities of shredded cellulosic material and a solution of amine oxide at an elevated temperature and stirring the mixture for a period of time by rotating mixer blades within the mixing chamber at a speed of between 40 and 80 r.p.m..
