Consolidated nonwoven
The present invention relates to a consolidated nonwoven consolidated by treatment with an aqueous binder composition comprising:a polymer P,a polyvinyl alcohol,optional a starch compound S andoptional at least one metal compound M selected from the group consisting of magnesium, calcium and zinc, in the form of an oxide, hydroxide, carbonate or bicarbonate,wherein the polymer P is obtainable by free radical aqueous emulsion polymerization of a monomer mixture of75 to 99% by weight of one or more monomers a) selected from the group consisting of esters of acrylic and/or methacrylic acid with alkanols of 1 to 12 carbon atoms, aliphatic conjugated diene and aromatic vinyl compound1 to 25% by weight of one or more monomers b) selected from the group consisting of N-methylolacrylamide, N-methylolmethacrylamide, glycidyl methacrylate and carboxylic acid-functional ethylenically unsaturated monomers≥0 to 15% by weight of one or more further ethylenically unsaturated monomer c) different from any of monomers a) and b)wherein the amounts of monomers a) to c) sum to 100 wt %,the water-based binder composition, the process of for producing the consolidated nonwoven and its use as reinforcing insert for bituminized roofing membranes.
