Abstract:
A method of forming a double-face velour fabric body, said method comprising the steps of:joining a filament loop yarn and a filament stitch yarn to form a fabric prebody, the filament stitch yarn forming a technical face of the fabric prebody and the filament loop yarn forming a technical back of the fabric prebody, the filament stitch yarn comprising heat sensitive material, finishing said technical face and said technical back of the fabric prebody, thereby to form a double-face velour fabric body having opposite velour surfaces, and exposing said fabric body to heating sufficient to cause a response by said heat sensitive material, thereby to increase tortuosity with a result of said fabric body having permeability of about 80 ft3/ft2/min or less under a pressure difference of Â½ inch of water across the fabric body.
