Abstract

A process for producing cellulose film comprises the steps of steeping a non-dissolving cellulose-containing pulp in a basic liquid, xanthating the steeped cellulose-containing pulp with carbon disulphide, dissolving the xanthated cellulose-containing pulp in a basic liquid to form a viscose solution, and casting a cellulose film from the viscose solution, wherein one or more of the following optimised processing conditions are employed: steeping is carried out, at least partially, at a temperature of about 30°C to about 50°C, steeping is carried out in a basic liquid having a concentration of base of about 16 to about 18% by weight, xanthation is carried out using about 30 to about 40% carbon disulphide by weight of cellulose present, xanthation is carried out, at least partially, at a temperature of about 20°C to about 30°C, dissolution is carried out, at least partially, at a temperature of about 10°C to about 25°C, dissolution results in a viscose solution having a base concentration of between about 5.5 and 7.5% by weight of the solution, and / or dissolution results in a viscose solution having a cellulose concentration of between about 8.5 and about 9.5% by weight of the solution.
