Title
(EN) METHOD FOR THE PRODUCTION OF SHAPED CELLULOSE BODIES
(KO) 셀룰로오스 성형체의 제조 방법
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.
