The present disclosure describes a method for the production of a spinning dope composition, said method comprising a homogenization involving mixing a cellulosic pulp material in alkali solution, mixing implying supplying a power density to agitators used in the homogenization of at least 150 kW/m3 (KW supplied to agitators per mixed unit of liquid volume), and thereafter a dissolution involving mixing of the cellulosic pulp material in the alkali solution to obtain a spinning dope composition, wherein the power density supplied to agitators used in the dissolution step is maximum 75 kW/m3 (KW supplied to agitators per mixed unit of liquid volume); and wherein the cellulosic pulp material in alkali solution is kept at a temperature of less than 0° C. during the homogenization and during at least part of the dissolution. The present disclosure is also directed to a system intended for the production of a spinning dope composition.
