Abstract
Abstract The invention consists of an improved method for making a fabric and the resulting fabric. The method provided includes the steps of applying a layer of acrylic foam to each surface of a thin cloth substrate. This acrylic foam may include fire retardant additives and additives which block light. The method further includes the step of embedding a thin layer of flock to the outer surfaces of the acrylic layers to impart a desired texture to them. The article provided includes a thin cloth substrate covered by at least one layer of acrylic on each of its sides and a thin layer of flock embedded in the outer surfaces of the acrylic layers.

Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
176 words
A multilayer fabric comprising: a substrate of cloth having an obverse and reverse surface; a first acrylic fire-retardent foam layer having an opaque pigment, adhered to said substrate, and covering said obverse surface of said substrate to provide a light barrier for said fabric and a smooth uniform first surface; a supplemental acrylic fire-retardant foam layer adhered to said first acrylic foam layer; a flock layer adhered to said supplemental acrylic foam layer to provide a first textured surface for said fabric; an inked design layer adhered to a portion of said first textured surface to provide a first finished surface for said fabric; a second acrylic fire-retardant foam layer adhered to said substrate and covering said reverse surface of said substrate to provide a smooth, uniform second surface for said fabric; a second flocked layer adhered to said second acrylic foam layer to provide a second textured surface for said fabric; and, a second inked design layer adhered to a portion of said second textured surface to provide a second finished surface to said fabric.
