Abstract

Release coated nonwoven sheet materials are provided through the process of (a) forming a web from fibers; (b) applying a water-based binder to the web; (c) applying a water-based release coating to one side of said web while the web is still wet from the application of the binder;
and (d) drying said web. This process eliminates at least one heating step, with unexpected control of the migration of the release coating through the web.

Claims (10)

1. A process for applying a release coating to a non-woven sheet material comprising:
a) forming a web from fibers;
b) applying a water-based binder to said web; and c) applying a water-based release coating to one side of said web while the web is still wet from the application of said binder; and d) drying said web.
2. The process of claim 1, which additionally comprises applying an adhesive to the dried web.
3. The process of claim 1 wherein the water-based binder is selected from the group consisting of latexes incorporating acrylics, styrene/butadiene rubbers, vinylacetate/ethylenes, vinylacetate/acrylates, polyvinyl chloride, polyvinyl alcohols, polyurethanes and vinylacetates.
4. The process of claim 1 wherein the water-based binder is a 25-35 percent solids aqueous dispersion.
5. The process of claim 1 wherein the release coating is a low adhesion backsize comprising poly(dimethyl siloxane).
6. The process of claim 1 wherein the release coating is a low adhesion backsize comprising acrylate polymers.
7. The process of claim 1 wherein the release coating is applied to the wet web within about 4 and 20 seconds after application of the binder.
8. The process of claim 1 wherein the web is dried by conveying the web through an oven.
9. The process of claim 8 wherein the oven has a heat source that is located on the release-coated side of the web as the web passes through the oven.
10. An adhesive tape prepared by the process of claim 2.
