Abstract
This invention is directed to a method for treating fibers by applying thereto a compound having the general formula ##STR1## wherein R.sub.1 is an alkyl group from 1 to 23 carbon atoms, R.sub.2 is an alkyl group from 1 to 23 carbon atoms, n is a number from 3 to 15, m is a number from 1 to 6, Y is --O-- or --S--, and X is --C.sub.2 H.sub.4 O-- or --C.sub.3 H.sub.6 O--, or a mixture of --C.sub.2 H.sub.4 O-- and --C.sub.3 H.sub.6 O--.
Claims18
A method for imparting lubricity in a fiber which comprises applying to said fiber a compound having the general formula ##STR4## wherein R.sub.1 is an alkyl group from 1 to 23 carbon atoms, R.sub.2 is an alkyl group from 1 to 23 carbon atoms, n is a number from 3 to 15, m is a number from 1 to 6, Y is --O-- or --S--, and X is --C.sub.2 H.sub.4 O-- or --C.sub.3 H.sub.6 O--, or a mixture of --C.sub.2 H.sub.4 O-- and --C.sub.3 H.sub.6 O--, and said compound is in an amount effective to provide lubrication.
A method for imparting lubricity to a fiber which comprises applying to said fiber a compound having the general formula ##STR5## wherein R.sub.1 is an alkyl group from 6 to 20 carbon atoms, R.sub.2 is an alkyl group from 1 to 3 carbon atoms, n is a number from 3 to 15, m is a number from 1 to about 6, Y is --O-- or --S--, and X is --C.sub.2 H.sub.4 O--, and said compound is in an amount effective to provide lubrication.
