ABSTRACT OF THE DISCLOSURE A secondary backing material for tufted carpeting and rugs having good strength and dimensional stability characteristics and sufficient porosity and air permeability to ensure good adhesive penetration for laminating to a primary backing. The material comprises a non-woven fabric made from essentially continuous polyester filaments, characterized by the non-woven fabric being built up from single filaments and filament groups in a crossed-over, parallel texture with a variation coefficient of the filament separation of more than 100%, and being of essentially constant filament and bond density through the depth of the fabric. The novel material avoids the disadvantages of natural materials, such as jute, which are not always readily obtainable and which are prone to rotting and natural deterioration.
