Abstract
The invention relates to the addition of an alkoxylate having the formula (I) X(NX-R).sub.n NX.sub.2 and/or an alkoxylate having formula (II) wherein X is hydrogen, the group R.sub.1 CO-, in which R.sub.1 is a hydrocarbon group having 7-23 carbon atoms or the group -(B).sub.m H, in which B is an alkyleneoxy group having 2-4 carbon atoms and m is 1-7, provided the number of groups of formula R.sub.ICO 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. ##STR1##
