Abstract

See full text

Materials have at least one layer comprising a mixture of thermoplastic and other fibers. This latter layer may be thermobonded together and then densified along at least a section of the eventual peripheral edge margin of an article to be formed from the material. Thermoplastic material-containing cover sheets may also be secured to the core and densified in this manner. The entire eventual peripheral edge margin of the article is typically densified. Fire retardant materials may be thermobonded within the layer to fix them within the article. The densified edge also helps to fix these materials in place. The composite materials are used in manufacturing infant car seat liners and other articles. Fire retardant films may be included as cover sheets for these materials. These films are typically bonded at every point of contact to an underlying core.
