Abstract:
A process for preparing a cellulose shaped body with improved strength, elongation, water absorption properties and reduced fibrillation, said process comprising dissolving a cellulose and a synthetic polymer having a molecular weight of from 5.sup.. 10.sup.3 to 1.sup.. 10.sup.7 selected from the group consisting of polyalkylene, polyacrylate, polymethacrylate, a copolymer of an acrylate or a methacrylate and another monomer having a molecular weight of from 5.sup.. 10.sup.3 to 1.sup.. 10.sup.7 and a polyalkylene glycol having a molecular weight of 1.sup.. 10.sup.4 to 5.sup.. 10.sup.5, in a tertiary amine oxide forming a solution, said solution containing up to 20% water based on the amount of the tertiary amine oxide, at a temperature from 70 to 130.degree. C., forming a shaped body from the solution and coagulating the shaped body in at least one bath under the removal of the tertiary amine oxide.
