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.
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.
