Abstract
According to the parent Specification, regenerated cellulose filaments are produced by extruding viscose, the cellulose of which has an average degree of polymerization of at least 400, at a salt point between 6 and 15, into an aqueous coagulating bath containing sulphuric acid together with zinc sulphate, the viscose containing between 0.5 and 10% by weight, based on the weight of the cellulose, of a polyethylene oxide of average molecular weight between 300 and 10,000, at a draw-off speed not substantially greater than that defined by the curve shown in Fig. 1 of the parent Specification, wherein the maximum permissible draw-off speed is plotted against the ball-fall viscosity of the viscose. This process is now modified by effecting the extrusion at a temperature between 40 DEG and 60 DEG C., whereby viscoses of relatively high viscosity can be spun at normal speeds.
