A binder composition comprising
a. at least one polycarboxy emulsion copolymer comprising from 10% to 25% by weight of a carboxy acid monomer,
wherein said copolymer has a measured Tg of from 40°C to 70°C, and a total weight solids of no less than 40%; and
b. at least one polyol crosslinker having a molecular weight of less than 700,
wherein said polyol crosslinker comprises a hydroxy group and at least one additional hydroxy group, wherein the ratio of primary hydroxy group equivalents to carboxy group equivalents is from 0.25 to 2.0.
A nonwoven mat comprising nonwoven fibers bound by the binder composition is also described. |
