Abstract

Glucose, glycerine, glycol, or other polyhydric alcohol is p added to the concentrated sulphuric acid spinning baths employed in the fine-spinning process described in Specification 166,931. By such addition the parchmentizing of the thread is obviated, and the concentration of the acid does not require to be so finely adjusted according to the ripeness of the viscose, Specifications 21405/07 and 5595/08 also are referred to.
