Abstract
Abstract A textured suede fabric lamina is produced by applying a thermoplastic compound to a flocked fabric. Desirably, the thermoplastic compound is expandable, that is having a blowing agent therein, so that upon heating an expanded infused layer is formed which can be sueded. The infused layer provides an improved appearance as well as improved physical properties such as feel, cleanability, color stability, and flock adhesion. A thin soil-resistant compound such as a halogenated polymer can be applied thereto. The textured suede lamina can be readily embossed.
