Abstract
Fibers in non-woven fibrous goods are bonded together by a crosslinked carboxylated acrylate polymer which forms a network of coalesced latex particles bonding contiguous fibers. This network exists as a non-continuous, porous film supported upon the fibers of the non-woven goods. The particles are of polymer derived from a crosslinked carboxylate latex containing from 1-20 phr of itaconic acid (IA) and at least 70 phr of one or more copolymerizable monomers one of which is an acrylate having the structure ##STR1## wherein R.sub.1 is hydrogen or methyl;
