    摘要: The invention is an amine-oxide process for the production of a cellulose moulded body, wherein a suspension of cellulose in an aqueous tertiary amine-oxide is converted into a cellulose solution which is moulded and passed through an aqueous precipitation bath. A moulded body is obtained which, optionally after washing, is treated with a crosslinking agent. The cellulose solution contains a substance whereby the crosslinking agent may be activated. The process according to the invention allows the production of fibres having effectively controllable fibrillation properties.
