Abstract
Non-woven fabrics are prepared from synthetic fibers by impregnating the fibers with a liquid binder system containing a polymer of from 35 to 60 weight percent of a hard monomer, 0 to 45 weight percent of butadiene or isoprene, 10 to 50 weight percent of an acrylate having from 1 to 8 carbon atoms in the ester portion and 1 to 5 weight percent of an ethylenically unsaturated mono- or dicarboxylic acid.
