Air-cured batting comprising a nonwoven web, advantageously in the form of a sheet, said batting comprising: - 75 to 97.5 wt % of fiber mixture; and - 2.5 to 25 wt % of resin comprising a cross-linked copolymer of butyl acrylate and methyl methacrylate, wherein the resin is present on a first surface of the batting, and on a second surface of the batting, the second surface being parallel to the first surface, and wherein the resin is adhered to fibers of the fiber mixture, thereby forming a bonded structure, such that, by virtue of the resin, the air-cured batting has structural integrity that imparts handleability of the batting in sheet form, wherein the fiber comprises natural fibers and/or synthetic fibers, and wherein the air-cured batting is formed by: applying a resin solution to the first surface of a batting intermediate and to the second surface of a batting intermediate to form a solution-applied batting structure, the resin solution comprising: - 15 to 60 vol. % of resin comprising a cross-linked copolymer of butyl acrylate and methyl methacrylate; - 20 to 80 vol. % of a solvent having an evaporation rate of greater than or equal to 1.3 that is soluble in water; and - 0 to 70 vol. % water, and exposing the solution-applied batting structure to air, thereby causing solvent in the resin solution to evaporate and resin to cure, thus forming the air-cured batting, wherein the resin is such that, in ambient conditions, it crosslinks within 48 hours at 25 °C, and/or when the solution-applied batting structure is exposed to forced air or circulated air having an air speed, at time of contact with the solution-applied batting, of 2.5 to 15 m/s, the solution-applied batting structure dries within 3 to 60 minutes. - 75 to 97.5 wt % of fiber mixture; and - 2.5 to 25 wt % of resin comprising a cross-linked copolymer of butyl acrylate and methyl methacrylate, wherein the resin is present on a first surface of the batting, and on a second surface of the batting, the second surface being parallel to the first surface, and wherein the resin is adhered to fibers of the fiber mixture, thereby forming a bonded structure, such that, by virtue of the resin, the air-cured batting has structural integrity that imparts handleability of the batting in sheet form, wherein the fiber comprises natural fibers and/or synthetic fibers, and wherein the air-cured batting is formed by: applying a resin solution to the first surface of a batting intermediate and to the second surface of a batting intermediate to form a solution-applied batting structure, the resin solution comprising: - 15 to 60 vol. % of resin comprising a cross-linked copolymer of butyl acrylate and methyl methacrylate; - 20 to 80 vol. % of a solvent having an evaporation rate of greater than or equal to 1.3 that is soluble in water; and - 0 to 70 vol. % water, and exposing the solution-applied batting structure to air, thereby causing solvent in the resin solution to evaporate and resin to cure, thus forming the air-cured batting, wherein the resin is such that, in ambient conditions, it crosslinks within 48 hours at 25 °C, and/or when the solution-applied batting structure is exposed to forced air or circulated air having an air speed, at time of contact with the solution-applied batting, of 2.5 to 15 m/s, the solution-applied batting structure dries within 3 to 60 minutes. applying a resin solution to the first surface of a batting intermediate and to the second surface of a batting intermediate to form a solution-applied batting structure, the resin solution comprising: - 15 to 60 vol. % of resin comprising a cross-linked copolymer of butyl acrylate and methyl methacrylate; - 20 to 80 vol. % of a solvent having an evaporation rate of greater than or equal to 1.3 that is soluble in water; and - 0 to 70 vol. % water, and - 15 to 60 vol. % of resin comprising a cross-linked copolymer of butyl acrylate and methyl methacrylate; - 20 to 80 vol. % of a solvent having an evaporation rate of greater than or equal to 1.3 that is soluble in water; and - 0 to 70 vol. % water, and exposing the solution-applied batting structure to air, thereby causing solvent in the resin solution to evaporate and resin to cure, thus forming the air-cured batting, wherein the resin is such that, in ambient conditions, it crosslinks within 48 hours at 25 °C, and/or when the solution-applied batting structure is exposed to forced air or circulated air having an air speed, at time of contact with the solution-applied batting, of 2.5 to 15 m/s, the solution-applied batting structure dries within 3 to 60 minutes.
