View Patent ↗Coating compositions, processes for making them and articles for cleaning composed of non-woven fabrics coated with the novel compositions are described.
1. An article for cleaning comprising:
a needle-punched fabric substrate;
an alkanolamide;
an imidazoline; and
an anionic surfactant;
wherein at least the alkanolamide and anionic surfactant are solid below 30° C. and are present within the article from a depth of ½ the thickness of the substrate to the outside surface of the article.
2. The article of claim 1 made by a process comprising: continuously applying to a surface of the substrate a coating composition comprising the alkanolamide, imidazoline, anionic surfactant, and at least 40% water.
3. An article for cleaning comprising:
a needle-punched fabric substrate;
an alkanolamide;
an imidazoline; and
a dialkylammonium chloride;
wherein at least the alkanolamide and dialkylammonium chloride are solid below 30° C. and are present within the article from a depth of ½ the thickness of the substrate to the outside surface of the article.
4. The article of claim 3 made by a process comprising: continuously applying to a surface of the substrate a coating composition comprising the alkanolamide, imidazoline, dialkylammonium chloride, and at least 40% water.
5. An article for cleaning comprising:
a needle-punched fabric substrate;
an alkanolamide;
an imidazoline; and
an ethylene oxide/propylene oxide block copolymer;
wherein at least the alkanolamide and ethylene oxide/propylene oxide block copolymer are solid below 30° C. and are present within the article from a depth of ½ the thickness of the substrate to the outside surface of the article.
6. The article of claim 5 made by a process comprising: continuously applying to a surface of the substrate a coating composition comprising the alkanolamide, imidazoline, ethylene oxide/propylene oxide block copolymer, and at least 40% water.
7. The article of claim 1 , 3 , or 5 , further comprising a wax.
8. The article of claim 1 , 3 , or 5 , wherein said article is a cloth, mitt, or glove.
9. The article of claim 1 , 3 , or 5 , wherein the article leaves a protective residue on a surface cleaned with the article.
10. The article of claim 1 , 3 , or 5 , wherein the substrate has a basis weight ranging from 2.5 to 10 ounces per square yard.
11. The article of claim 10 , wherein the substrate has a basis weight ranging from 5 to 7 ounces per square yard.
12. The article of claim 1 , 3 , or 5 , wherein the substrate has a thickness ranging from 40 to 150 mils.
13. The article of claim 12 , wherein the substrate has a thickness ranging from 60 to 80 mils.
14. The article of claim 1 , 3 , or 5 , wherein the substrate comprises at least one of the group consisting of: acrylic, rayon, cotton, nylon, polypropylene, and polyester.
15. The article of claim 1 , 3 , or 5 , wherein the substrate comprises a material having a melting point above 140° C.
