ABSTRACT:
An insulative fabric generally comprises a central sheet of breathable, substantially crinkle-free, pliant, aluminized polymeric film and spaced layers of hollow, microtubular, filamentous synthetic insulation sandwiching the film. The polymeric film has sufficient tensile strength for use as a quilting fabric in quilts, comforters, or clothing, and its tensile strength may be enhanced by use of a scrim backing sheet placed directly adjacent the film. The spaced layers of synthetic insulation are individually needle-punched through the film to reduce the overall thickness of the insulation without substantially reducing the insulative capacity of the fabric and to provide passageways through the film so that the film is breathable. In this manner, the fabric has a soft, fleecy quality, is of a substantially uniform thickness, and is substantially noiseless when folded or wrinkled.
