Abstract
Abstract This invention relates to a process for the production of a shaped body from a cellulose derivative which comprises extruding a viscose solution through a shaping die into a precipitation bath and passing the shaped body thus formed through regenerating and washing baths, then treating the body with an acid aqueous solution of a secondary chemical plasticizer, drying it by heating, and finally moistening it with water after drying, said viscose solution being mixed with a liquid containing alkyl-trimethylol-urea of the following general formula <IMAGE> wherein n is a whole number between 9 and 24, preferably between 14 and 19, and especially the number 17, and/or with a liquid containing alkyl-ethylene-urea of the following general formula <IMAGE> wherein n is a whole number between 11 and 19, preferably between 15 and 18, and especially the number 17, or with a liquid containing alkylamine-bis-dimethylene-triazinonetetramethylol of the following general formula <IMAGE> <IMAGE> wherein n is a whole number between 9 and 24, preferably between 14 and 19, and especially the number 17, or with a liquid containing alkylamide-bis-dimethylene-triazinonetetramethylol of the following general formula <IMAGE> <IMAGE> wherein n is a whole number between 9 and 24, preferably between 14 and 19, and especially the number 17.
