Definitions

  • Tufted fabrics such as carpets and rugs, are made up of various components and different types of material.
  • the components generally include a primary backing, secondary backing, latex adhesives and tuft material.
  • Tufted fabrics generally have a primary backing of natural or synthetic polymeric materials such as polypropylene in a woven or nonwoven fabric form.
  • broadloom carpets are normally produced by having a primary backing of woven slit film made from polypropylene into which there is inserted a plurality of tufts by a tufting machine. Tufts are inserted into the primary backing.
  • the present invention is a tufted fabric having a fibrous primary backing layer, a plurality of fibrous tufts each made of a bundle of yarns forming a pile layer on the face side of the primary backing layer and extending through the backside of the primary backing layer to form a plurality of loops, wherein the loops are anchored to the primary backing layer either through entanglement or through heating the primary backing layer to cause fusion of the loops to the back of the primary backing layer.
  • the amount of the binder fiber is from 5% to 95% of the blend, preferably from 15% to 30% of the blend. As the proportion of the binder fiber in the blend is increased, the resulting heat bonded backing will generally have greater rigidity. The amount of bonding will depend most importantly on whether binder is available to bond the polyester fiber at the crossover point, and the statistical probability of this increases with an increase in the amount of binder.
  • the structure may be a stitch bonded fabric.
  • the carpet may be further processed, including dyeing and heat treating.
  • the blended fibers were carded into a web, and a batting was prepared by crosslapping the webs on standard crosslapping laps.
  • the batt was 15.2cm (6 inches)thick made up of 10.
  • the batting was then needle punched to entangle the blended fibers and to reduce the batting to the primary backing having a thickness of 2.54mm (0.10 inches).
  • the weight of the primary backing was 475 g/m 2 (14 oz./sq. yard).
