An article comprising at least one cured, liquid-impervious polymeric shell substantially free from defects, at least one liner, and a non-tacky, thermoplastic adhesive layer between the shell and the liner, wherein the adhesive layer is melted and solidified to create a non-tacky bond between the shell and the liner, which can be moisture-absorbing or cut-resistant, whereby the liner supports and limits stretch ability of the shell, thereby preventing adhesive delamination between the adhesive layer and either of the shell and/or the liner; a method for the manufacture of an article comprising a supported, polymeric shell, such as a glove, a gauntlet, an apron, or a boot, comprising providing a cured, liquid-impervious, polymeric shell, providing a knitted/woven liner, incorporating a non-tacky, thermoplastic adhesive layer between the shell and the liner, such as by hot-melt spraying, dry-powder spraying or fiber-coating, creating intimate contact between the shell, the adhesive layer, and the liner, subjecting the shell, the adhesive layer, and the liner to infrared radiation to melt the adhesive layer and create a bond between the shell and the liner, and cooling the shell; as well as other methods.

What is claimed is: 1. A method for the manufacture of a supported, polymeric shell article comprising the steps of:a) providing a cured, liquid-impervious, polymeric shell produced by dipping a coagulant-coated former into an aqueous latex emulsion, gelling a latex layer on the former, and heating
What is claimed is: 1. A method for the manufacture of a supported, polymeric shell article comprising the steps of:a) providing a cured, liquid-impervious, polymeric shell produced by dipping a coagulant-coated former into an aqueous latex emulsion, gelling a latex layer on the former, and heating the gelled latex layer on the former to crosslink and cure the latex layer;b) providing a liner knitted or woven using fibers selected from the group consisting of cotton, rayon, polyester, polypropylene, Kevlar™, Spectra™, steel wire, or a combination thereof;c) disposing a non-tacky, thermoplastic adhesive layer between the shell and the liner and disposing the shell, adhesive layer and liner on a skeletal support;d) inflating the shell placed over the skeletal support with air pressure to create intimate contact between the polymeric shell, the adhesive layer, and the liner;e) subjecting the shell with the adhesive layer and the dressed liner to infrared radiation, thereby melting the adhesive layer and creating a bond between the shell and the liner; andf) cooling the shell with the adhesive layer and the liner to create the supported, polymeric shell article.
