IMPROVED PROCESS FOR DISSOLVING CELLULOSE CARBAMATE

摘要

The invention relates to cellulose carbamate solutions having improved capacity for fiber spinning or film formation therefrom. The addition of urea to the aqueous alkali in which the cellulose carbamate is dissolved results in an increase in the amount of cellulose carbamate that can be dissolved and a decrease in the viscosity and clogging number of the solution as compared to such solutions without urea.
