Abstract

Relates to the manufacture of very fine artificial silk threads from viscose according to the draw-spinning process described in Specification 166,931. To obtain highly lustrous threads the individual filaments of which do not stick together, and to obviate the necessity for the careful adjustment of the degree of ripeness of the viscose, there is added to the highly concentrated acid spinning baths employed a solution of cellulose, coagulated waste viscose, or concentrated sulphite-cellulose lyes in 80 per cent sulphuric acid, the solution being prepared with out heating; the solution is diluted so as to give the required acid concentration in the bath. Specifications 21405/07, 145,627, 147,416, and 181,900 are referred to.
