At least one layer of non-woven batt material is affixed to the base fabric, typically by needling. The flat woven base fabric includes from at least 30 to 50 machine direction, crimped warp yarns per inch for a single layer weave and at least 60 to 100 machine direction, crimped warp yarns per inch for a multi-layer weave. 16
