ABSTRACT:
The following invention provides a fragrant wall covering having a polymer entrapped emollient-moisturizer composition incorporated therein. Since the emollient-moisturizer composition is incorporated into a dry blend of the polymeric material which is used to make the wall covering, the emollient-moisturizer composition is distributed substantially evenly throughout the polymer of the wall covering. In the illustrated embodiment of the invention, the emollient-moisturizer composition comprises a volatilizable material having a strong, recognizable odor. Because of its even distribution in the polymer of the wall covering, the volatilizable material is released gradually into the atmosphere, and the wall covering retains said recognizable odor for a substantial period of time. A method of making the wall covering of the invention is provided in which the polymer used to make the wall covering is extruded, the density of the polymer is measured as it is extruded, and the data obtained by measuring the density of the polymer is fed into a computer which controls the thickness of the extruded material and the speed of calendering rollers on which the material is extruded, in order to provide a layer of material having substantially uniform thickness.
