ABSTRACT:
A process for making composite articles, such as upholstery, filled with a cellular polyurethane foam covered by a breathable, porous fabric includes coating one surface of the fabric and the pores therein with a strippable coating. The fabric is then placed in a mold with the coating against the inside of the mold and is pulled down into conformity with the mold by vacuum. A liquid polyurethane foam resin is poured in place behind the fabric and foamed to a flexible solid state. The article is removed from the mold and the coating is stripped to complete the process.
