Abstract
A secondary carpet backing fabric woven from man-made fiber warp and weft yarns, the warp yarns preferably being ribbon, including fibrillated, yarns, and at least some of the weft yarns having a random intermingled array of loops and filaments, weft yarns not having a random intermingled array of loops and filaments preferably being such ribbon yarns. Preferably, the secondary backing fabric has an open weave construction of leno structure. These backing fabrics having unusually strong adhesion because of the open structure of the weft yarns which have the random intermingled array of loops and filaments. Air textured core and effect yarns are especially suitable. Carpets having this secondary backing can be glued down to a floor with good adhesion.
