The apparatus of the present invention comprises a foam bonding agent layered between fabrics or other materials where the foam possesses wind-resistant and breathable characteristics independent of the other layers.

In one embodiment, the first step includes lightly exposing a thin polymer foam (such as polyester polyurethane or polyether polyurethane) to a flame without preheating, then pressing it against the inner face of mesh or tricot. The second step includes more vigorously exposing the foam face of the foam-mesh or foam-tricot laminate to a flame, then pressing it against the inner face of a berber, pile, or fleece fabric.

Abstract: A method for forming an angled plastic article of varying density whereby a blowing agent is added to a plastic material and the material is injected into a mold cavity of a mold unit. The interior walls of the mold cavity are maintained at a temperature sufficient to prevent the outer skin of the hardening plastic article from producing gas bubbles. The volume of the mold cavity is increased to allow bubbles to produce and uniformly distribute themselves throughout the mold cavity and then a reconversion phase is instituted whereby the desired density of the finished plastic article is achieved without voids or aberrations appearing in the surface of the plastic article. The mold unit is provided with extensible beveled edges which extend and retract as the mold cavity is enlarged and compressed. By this method, a resulting plastic article of varying density is produced having grooves running the length of the article.

Abstract: A woven fabric is formed from polypropylene fibers by simply weaving the fabric using polypropylene fibers in both the warp and weft directions. The edges are left frayed and could become unraveled. In order to prevent the fabric from fraying further, particularly during washing, binding fibers are incorporated at least in the weft direction, but only along the edges. The binding fibers are polyester fibers coated with a low-melting-point thermoplastic adhesive. The thermoplastic adhesive is one that melts at a temperature lower than the melting point of the polypropylene fibers. Once these are incorporated into the fabric at the loom, the fabric is placed in an oven and heated to a temperature above the melting point of the thermoplastic adhesive and below the melting point of the polypropylene fibers to cause the thermoplastic adhesive to melt, binding the polypropylene fibers together.
