Abstract
A floor covering is provided which has a woven fabric needle punched to a face surface of a non-woven batt of staple fibers. The woven fabric has either warps of polypropylene ribbons and fillings of continuous filaments, ribbon yarns, or spun staple fibers or vice versa. The needle punching forms a covering layer of fibers on the facing surface of the woven fabric. In one form of the invention, the needled batt and woven fabric is texturized from the batt side of the woven fabric which forms loops outwardly of the plane of the woven fabric which loops include fibers from the non-woven batt and varying amounts of filaments, ribbon yarns, or spun staple fibers from the woven fabric. A back is affixed to the batt as by fusing, latexing, foaming, needling, or the like. In another form of the invention, the needled batt and woven fabric are texturized from the woven fabric side of the batt which forms loops outwardly of the plane of the batt. The loops contain fibers from the batt and from the filaments, ribbon yarns, or spun fibers. In this form of the invention, the woven fabric serves also as a woven backing for the floor covering. A novel method of making a floor covering is disclosed and comprises needling the non-woven batt, attaching the woven fabric which has either warps or fillings, containing bundles of continuous filaments, ribbon yarns, or spun staple fibers to the batt to provide a covering layer to the batt, texturizing loops from the non-woven fibers of the batt and from the continuous filaments, ribbon yarns, or spun staple fibers of the woven fabric to define rows of loops on the floor covering which has a random pattern of individual loops or clusters of loops of a color contrasting with the color of the batt. The floor covering has an appropriate backing formed thereon or attached thereto.
