Title:
FUNCTIONALIZATION OF FOREIGN MATERIAL IN A LYOCELL METHOD
Document Type and Number:
WIPO Patent Application WO/2019/138091
Kind Code:
A1
Abstract:
The invention relates to a method for producing a regenerated cellulosic molded body (102). The method has a step of supplying (52) a starting material (110) which has cellulose and at least one foreign material, converting at least a proportion of the starting material (110) together with at least a proportion of the at least one foreign material into a spinning mass which additionally contains a solvent (116) for dissolving (54) at least a proportion of the cellulose of the starting material (110) in the solvent (116), and extruding (70) the spinning mass in order to form the molded compound (102) and subsequently precipitating (56) same into a spinning bath (191), whereby the molded body (102) is obtained, wherein the molded body (102) has cellulose and at least a proportion of the at least one foreign material.
