<p>This invention relates to a method of making fabric-faced upholstered items. The items are made by vacuum forming under heat a laminate of a cast highly plasticized vinyl chloride homopolymer or copolymer sheet and a readily extensible fabric, and the resulting shaped cover is filled with a foam which is foamed in situ, the foam bonding to the thermoplastics sheet of the laminate and holding the laminate in shape. The laminate must have an extensibility in two directions at right angles of at least 25% under a load of 51b per 2 inch wide strip when subjected to loads of 51b applied at right angles to one another to the edges of a 2 inch side square of the fabric, and be capable of increasing its surface area by at least 50%. The fabric can have this high degree of extensibility and still be suitable as a cover because the laminate is bonded to the foam filling and so held to shape.</p> |
