Title
(EN) Method for the production of shaped cellulose bodies
(ZH) 制备纤维素模制体的方法
Abstract
(EN)
The invention relates to a method for producing shaped cellulose bodies according to the amine oxide method comprising the following steps: a cellulose solution is shaped in an aqueous tertiary amine oxide; the shaped solution is precipitated; and the obtained shaped body is washed and dried. The inventive method is characterized by the fact that a chitosonium polymer is added to the cellulose solution and/or a precursor of said solution, and/or the shaped body is treated with a chitosonium polymer before being dried, said chitosonium polymer being essentially entirely soluble in a standard spinning solution.
