Abstract
A sizing composition consisting of a polyvinyl alcohol and of from 1 to 30, preferably 5 to 15, weight %, referred to the polyvinyl alcohol, of an amine oxide of the formula ##STR1## wherein R.sub.1 is C.sub.5 -C.sub.22 alkyl, R.sub.2 is C.sub.1 -C.sub.22 alkyl or a group of the formula--(CH.sub.2 CH.sub.2 O).sub.n H with n being an integer of from 1 to 5 and R.sub.3 is C.sub.1 -C.sub.5 alkyl or a group of the formula--(CH.sub.2 CH.sub.2 O).sub.m H with m being an integer of from 1 to 10, if R.sub.2 is alkyl having not more than 5 carbon atoms, the sum of n+m being not greater than 10.
