Abstract
Regenerated cellulose filaments and films are produced by spinning viscose containing either (a) an oxyalkylated ammonia of the general formula: <FORM:0846533/IV(a)/1> in which n, x, y and z are integers, the sum of x, y and z being at least 10, and R1, R2 and R3 are each hydrogen atoms or alkyl radicals, or (b) an oxyalkylated ammonia of the general formula: <FORM:0846533/IV(a)/2> in which n, x, y, z, R1, R2 and R3 have th previously specified meanings and X is the radical of an organic saturated or unsaturated, sulphated or non-sulphated acid or oxyacid, into a bath containing sulphuric acid, sodium sulphate and at least 3% by weight of zinc sulphate and stretching in a second, hot bath. The viscose preferably contains 0,8 to 5g, per kilogram of the oxyalkylated ammonia. Examples describe the spinning of viscose containing compounds having the formulae: <FORM:0846533/IV(a)/3> in which X represents <FORM:0846533/IV(a)/4> and <FORM:0846533/IV(a)/5> stretching being carried out in a hot bath containing 2% by weight of sulphuric acid and having a temperature of 95 DEG C.
