Claims
- 1. A composition for imparting non-permanent soil-release characteristics to textile fabrics comprising a copolymer of an ethylenically unsaturated monocarboxylic monomer and a lower alkyl acrylate or methacrylate, said polymer having an acid equivalent weight of from about 110 to 175 and a water-soluble salt of a polyvalent metal, said salt being selected from the group consisting of water-soluble salts of magnesium, calcium, zirconium, tin, aluminum, zinc and barium.
- 2. The composition of claim 1 wherein the water-soluble salt is a magnesium salt.
- 3. The composition of claim 1 wherein the water-soluble salt is a calcium salt.
- 4. The composition of claim 1 wherein said acid is selected from the group consisting of acrylic, methacrylic, ethacrylic and crotonic.
- 5. The composition of claim 1 wherein said acid is methacrylic acid.
- 6. The composition of claim 1 wherein said acrylate is ethyl acrylate.
- 7. The composition of claim 1 wherein said acid is employed in amounts of about 60 to 70% and said acrylate in amounts of 40 to 30% by weight.
- 8. The composition of claim 1 wherein said polymer has an acid equivalent of about 110 to 125.
- 9. The composition of claim 1 wherein said polymer has a molecular weight of about 2,000 to about 2,000,000.
- 10. The composition of claim 1 wherein the ratio of said polyvalent metal salt to said copolymer is from 1:5 to 20:1.
- 11. The composition of claim 1 wherein the polymer has a molecular weight of about 1 million.
- 12. A dilute aqueous solution of the composition as defined in claim 1 containing about 0.01 to about 1.0% by weight of said composition.
- 13. A solution as defined in claim 12 having a pH in the range of about 4.5 to about 9.5.
- 14. A solution as defined in claim 13 containing about 0.001 to about 1.0% of said salt.
- 15. A soil resistant synthetic fiber-containing material having an effective amount of the composition as defined in claim 1.
- 16. A material as defined in claim 15 wherein said fiber is selected from the group consisting of polyester, polyamide, acrylic, cellulose, cotton-synthetic blends regenerated cellulose and blends thereof.
- 17. A method of rendering synthetic fiber-containing materials soil resistant comprising applying thereto an effective amount of a solution as defined in claim 12.
- 18. A composition as defined in claim 12 wherein the ratio of said acid to said acrylate or methacrylate is about two thirds acid to about one third acrylate or methacrylate.
- 19. The composition of claim 1 wherein the relative ratios of the two monomers is about 50:50 to 75:25.
