Abstract
The invention relates to a process for the production of cellulose carbamate solutions for use in the production of cellulose fibres which are spun from cellulose carbamate solutions by means of conventional processes in which the cellulose is contacted with the urea followed by the conversion of the cellulose with the urea followed by production of the cellulose carbamate solution. According to the invention, the cellulose carbamate is subjected to a hydrolytic treatment, whereby said hydrolytic treatment takes place as the intermediate stage between the formation of the cellulose carbamate and its dissolution for the production of cellulose carbamate.
