ABSTRACT:
A laminated fabric having an integral raised area formed therein which simulates the appearance of a button, welt or the like, and method of making same. The laminated fabric is comprised of a layer of cloth or vinyl cover material, an intermediate layer of foam and a layer of backing material such as nylon. A form having the shape which corresponds to the desired shape of the raised area is disposed between the foam layer and the cover material. Anhydrous polyurethane foam forming materials are applied in liquid form to the form layer and cover material contact surface and the form layer and backing material contact surface. The unlaminated layers are placed over a die with each of the forms being positioned immediately above a die having protrusions which generally circumscribe the form. Moisture is introduced into the foam forming material and a heated press is applied to the backing material forcing the unlaminated layers down against the die. The resultant heat and pressure cause a foaming reaction of the foam forming materials which results in a foam bonding layer which bonds the cover material in substantial contact with the backing material in the region surrounding the form. The bonding layer also bonds the cover material and the backing material to substantially all of the remainder surface area of the foam layer.
