Abstract:
A spin bath solution for the regeneration of cellulose which comprises an alkoxylated polyamine surfactant having the general formulaRNA.paren open-st.C.sub.n H.sub.2n NA.paren close-st..sub.x-1 A (I)where R represents a hydrogen or an aliphatic group with 1-24 carbon atoms, each A represents hydrogen, an aliphatic group with 1-24 carbon atoms or an H(OC.sub.m H.sub.2m).sub.y -group, where m is a number from 2-3, y is a number from I to 5, n is a number from 2-3, x is 4-8, with the proviso that the number of H(OC.sub.m H.sub.2m).sub.y -groups are from 1 to x+1, and the total number of carbon atoms in the aliphatic groups is from 8 to 45, as a viscose spin bath additive.
