Abstract
A stitched fabric including a barrier layer; a yarn stitched through and forming stitch holes in the barrier layer, and a foam core formed over the barrier layer. A melted portion of the barrier layer fills at least a portion of the stitch holes. The foam core is prevented from progressing further into the stitched fabric by the barrier layer. As such, the barrier layer is configured to control a depth to which the foam core penetrates into the stitched fabric. The foam core may be formed over at least a portion of the yarn. A second foam core may be formed on a side of the barrier layer opposite the foam core.
