Claims
- 1. A fiber lubricant consisting essentially of a low-friction lubricating component and an acrylamido-C.sub.1 -C.sub.6 -alkane sulfonic acid polymer or salt thereof having an average molecular weight of at least about 500,000.
- 2. The fiber lubricant of claim 1, wherein the average molecular weight of the polymer is from about 1,000,000 to about 10,000,000.
- 3. The fiber lubricant of claim 1, wherein the average molecular weight is from 3 to 4 million.
- 4. The fiber lubricant of claim 1, wherein the lubricating component is a silicone emulsion.
- 5. The fiber lubricant of claim 2, wherein the polymer is present in an amount of at least about 0.01 wt. % active polymer, based on the total weight of the lubricant.
- 6. The fiber lubricant of claim 5, wherein the polymer is present in an amount of from about 0.01 to 1.5 wt. % active polymer, based on the total weight of the lubricant.
- 7. The fiber lubricant of claim 3, wherein the polymer is an acrylamidomethylpropane sulfonic acid homopolymer, or water-soluble salt thereof.
- 8. The fiber lubricant of claim 6, further containing a corrosion inhibitor.
- 9. The fiber lubricant of claim 1, wherein the lubricating component is a polyethylene or paraffin wax emulsion.
- 10. A method for lubricating textile fibers for processing to reduce fiber-to-metal friction comprising treating the fibers with the lubricant of claim 1.
- 11. The method of claim 10, wherein the fibers are wet-processed.
- 12. The method of claim 10 wherein the fibers are 100% cotton or a cotton blend.
- 13. The method of claim 12, wherein the processing comprises high-speed knitting.
- 14. The method of claim 12, wherein the fibers have a moisture content of at least 6% by weight, based on the weight of the fibers.
- 15. A method for improving the lubricating effect of a lubricant for use on textile fibers to reduce fiber-to-metal friction during processing comprising incorporating an acrylamido-C.sub.1 -C.sub.6 -alkane sulfonic acid polymer additive having a molecular weight of at least 500,000 into the lubricant.
- 16. The method of claim 15, wherein the textile fibers are 100% cotton, or a cotton blend.
- 17. The method of claim 16, wherein the fibers contain from about 6 to 8% by weight water, based on the weight of the fibers.
- 18. The method of claim 15, wherein the lubricant is a silicone-based lubricant.
- 19. The method of claim 15, wherein the polymer has a molecular weight of from about 1,000,000 to about 10,000,000.
- 20. The method of claim 19, wherein from about 0.01 to 1.5% by weight polymer is incorporated into the lubricant.
- 21. The method of claim 15, wherein the textile fibers are cotton, polyester, rayon, nylon, acrylic or a blend of at least two of these fibers.
- 22. The method of claim 10, wherein the textile fibers are cotton, polyester, rayon, nylon, acrylic or a blend of at least two of these fibers.
