Claims
- 1. 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.
- 2. The method of claim 1 wherein R.sub.1 is an alkyl group from 6 to 20 carbon atoms.
- 3. The method of claim 2 wherein R.sub.1 is an alkyl group from 16 to 18 carbon atoms.
- 4. The method of claim 2 wherein R.sub.1 is an alkyl group from 12 to 14 carbon atoms.
- 5. The method of claim 4 wherein R.sub.1 is an alkyl group from 8 to 10 carbon atoms.
- 6. The method of claim 1 wherein R.sub.2 is methyl group.
- 7. The method of claim 1 wherein n is 3 to 5.
- 8. The method of claim 1 wherein n is 5.
- 9. The method of claim 1 wherein m is 1 to 3.
- 10. The method of claim 1 wherein m is 1.
- 11. The method of claim 1 wherein X is --C.sub.2 H.sub.4 O--.
- 12. The method of claim 1 wherein Y is --O--.
- 13. 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.
- 14. A method as claimed in claim 13, wherein R.sub.2 is a methyl group, n is 5, m is 1 and X is --C.sub.2 H.sub.4 O--.
- 15. A method as claimed in claim 14, wherein R.sub.1 is an alkyl group from 16 to 18 carbon atoms.
- 16. A method as claimed in claim 14, wherein R.sub.1 is an alkyl group from 8 to 10 carbon atoms.
- 17. A method as claimed in claim 14, wherein R.sub.1 is an alkyl group having 18 carbon atoms.
- 18. A method as claimed in claim 14, wherein Y is --O--.
