Definitions

  • the polyurethane tie coat composition is preferably applied directly to the underside of the carpet facing, to wet out the fiber bundles and adhere them to the primary backing. This is conveniently done by creating a puddle of the tie coat composition on the underside of the carpet facing and mechanically spreading the composition over the back surface. It is preferred to froth the tie coat composition before applying it, as frothing makes it easier to control coating weight. A suitable froth density is from about 400 kg/m 3 to about 800 kg/m 3 . It is preferred to use a doctor blade or similar apparatus to spread the tie coat composition, as this method mechanically pushes the tie coat composition into and between the fiber bundles and into contact with the primary backing, thereby improving the bond between the fibers and primary backing.
  • Another suitable apparatus for applying the tie coat composition is an application roll. Once the tie coat composition is applied and spread onto the carpet facing, the reinforcing scrim can be brought into contact with the layer of the tie coat composition. The tie coat composition then is allowed to cure to form a polyurethane polymer. Alternatively, more of the tie coat composition can be applied separately to the reinforcing scrim, in the same manner as just described, and the coated carpet facing and coated reinforcing scrim- can be joined, tie coat layer-to-tie coat layer, followed by curing the tie coat composition, to form the assembly. This latter method has the advantage of getting excellent penetration of the tie coat composition into both the carpet facing and the reinforcing scrim, although capital and operating costs may tend to be higher.
  • the cap coat composition is preferably filled. Fillers and amounts thereof as described with regard to the tie coat composition are suitable. Similarly, the cap coat composition preferably contains a filler wetting agent, as described with regard to the tie coat composition. Catalysts as described with respect to the tie coat composition are preferably used.
  • a preferred catalyst is a delayed action catalyst, such as the dialkyltin sulfide catalysts described in U. S. Patent No. 5,646,195, and especially the dimethyl-, dibutyl- and dioctyltin sulfide catalysts.
  • the effectiveness of the tie layer in binding the facing fibers to the primary backing can be expressed in terms of tuftbind.
  • the finished floor covering product of the invention advantageously exhibits a tuftbind, measured according to ASTM D 1335, of at least 10 Ib (44.5N), more preferably at least 13 Ib (58N) and even more preferably at least 15 Ib (67N).
  • Wet tuftbind values are advantageously at least 5.5 Ib (24N), more preferably at least 8.8 Ib (39N) and even more preferably at least 11 Ib (49N).
  • Wet tuftbind is measured according to ASTM D 1335 after soaking the carpet sample in room temperature tap water for 20 minutes. Another indication of the effectiveness of the tie layer is edge ravel.
