METHOD FOR IMPROVING THE RHEOLOGY AND THE PROCESSABILITY OF CELLULOSE-BASED SPINNING SOLUTIONS

摘要

The invention relates to the addition of an alkoxylate having the formula (I) X(NX-R)nNX2 and/or an alkoxylate having formula (II) wherein X is hydrogen, the group R1CO-, in which R1 is a hydrocarbon group having 7-23 carbon atoms or the group -(B)mH, in which B is an alkyleneoxy group having 2-4 carbon atoms and m is 1-7, provided the number of groups of formula R1CO is 1 or 2 and the total number of B is 2-20, R is an alkylen group having 2-3 carbon atoms and n is 2-10, preferably 3-7, to improve the rheology and the processability of a cellulose-based spinning solution.
