Abstract (en)

[origin: WO2014086883A1] The invention relates to a method for producing a cellulosic molded body in accordance with the viscose method by shaping a spinning mass containing cellulose xanthate. The method is characterized in that xylan is added to the cellulose xanthate at a fraction of at least 1 wt%, with respect to cellulose, preferably 1 wt% to 20 wt%, especially preferably 3 wt% to 15 wt%. The invention further relates to cellulosic molded bodies, obtained in accordance with the viscose method, having a fraction of high-molecular-weight xylan having an average degree of polymerization (DP) of 75 to 350, preferably 110 to 220, of at least 0.5 wt%, preferably 2 wt% to 8 wt%.
