Woven textile

A woven polypropylene secondary backing comprising polypropylene ribbon warp members that are from 0.5 to 4 mils thicks and heavily fibrillated polypropylene ribbon as the fill member, the fibrils in said fibrillated ribbon being from 3 to 235 denier, having an average denier of about 12 to about 150, the backing characterized by a tensile strength greater than 30 pounds in the warp direction, and greater than 25 pounds in the fill direction and a delamination strength greater than 7.5 pounds.

A woven polypropylene secondary carpet backing comprising ribbon polypropylene warp members from 0.5 to 4 mils thick, and from 75 to about 120 mils wide and heavily fibrillated polypropylene fill members whose fibrils are from 4 to 200 denier having an average denier of about 15 to about 100, said secondary backing characterized by a tensile strength greater than 30 pounds in the warp direction, and greater than 25 pounds in the fill direction and delamination strength greater than 7.5 pounds.

A synthetic woven fabric comprising warp members and fill members, at least one of which comprises heavily fibrillated synthetic ribbon, the fabric being characterized by a tensile strength greater than 25 pounds in the fibrillated ribbon direction and a delamination strength greater than 7.5 pounds when laminated to a soft carpet.

A synthetic woven fabric comprising warp members and fill members, at least one of which comprises heavily fibrillated synthetic ribbon, the fabric being characterized by a tensile strength greater than 25 pounds in the fibrillated ribbon direction and having been processed to raise fibril ends above the plane of the fabric.

A synthetic woven secondary carpet backing comprising warp and fill members at least one of said members comprising heavily fibrillated ribbons of polyolefin, polyamide, polyester or mixture thereof having fibrils from 3 to 235 denier and an average denier from about 12 to about 150 the backing characterized by a tensile strength greater than 25 pounds in the fibrillated ribbon direction and a delamination strength greater than 7.5 pounds when adhered to a soft carpet.

A carpet structure comprising

• (a) a primary backing containing a face pile attached thereto and
• (b) a secondary backing adhered to the underside of said primary backing and comprising synthetic warp members and fill members woven into a fabric, at least one of said warp and fill members comprising heavily fibrillated synthetic ribbon, the secondary backing characterized by a tensile strength greater than 25 pounds in the fibrillated ribbon direction and a delamination strength greater than 7.5 pounds.

A method of aftertreating woven textile and textile being woven of polyolefin ribbon warp members and heavily fibrillated fill members to raise the fibril ends of said fibrillated members above the surface of the textile which comprises needling said textile by barbed needles, said needles being reciprocated from about 350 to 800 strokes per minute to penetrate said textile at a depth of 5/8 inches to about 15/32 inch and from about 100 to about 300 penetrations per square inch of textile.

A method of making a synthetic secondary carpet backing which comprises processing a fabric woven of synthetic warp and fill members, wherein at least one of the warp and fill members comprises heavily fibrillated synthetic ribbon, to raise fibril ends above the plane of the fabric, the resulting secondary carpet backing characterized by a tensile strength in the fibrillated ribbon direction greater than 25 pounds and a delamination strength greater than 7.5 pounds when laminated to a soft carpet.
