Abstract
Abstract The present invention relates to a textile laminate comprising a fiberfill web substrate and a face layer. The fiberfill web substrate has a plurality of first fibers at the surface of the substrate. The face layer comprises a plurality of extruded second fibers which are mechanically intertangled with the plurality of first fibers at the surface of the substrate to thereby form the textile laminate. Typically, the first fibers of the fiberfill web are polyester fiberfill fibers and the second fibers of the extruded face layer are polypropylene fibers.
