Abstract (en)

[origin: WO2018081771A1] Air-cured batting includes a nonwoven web. The batting contains 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. Articles comprising the air-cured batting and methods of making the air-cured batting are also provided.
