摘要：
The invention relates to a method for the production of cellulose carbamate by reactive extrusion and for the production of moulded articles made of regenerated cellulose. The method for the production of cellulose carbamate is based thereby on the activation of cellulose, subsequent separation of the activation solution and following thereon reactive extrusion of the activated cellulose. Typical examples of moulded articles which can be produced therefrom are fibres, films, beads, sponges or sponge-type cloths.
