  • Publication number: 20090062432
    Abstract: At least certain embodiments of the present invention relate to polyurethane compositions for forming a layer of polyurethane on a textile, fabric or material, such as a flooring fabric or a non-flooring fabric. The compositions comprise the reaction product of castor oil having a water content of less than or equal to about 0.2% by weight; a monol, and an isocyanate, wherein the reactants have a soft segment functionality of about 2.0 to about 2.64. Methods of using the compositions and products including the compositions are also disclosed. At least selected embodiments may provide compositions for use in surface coverings such as floor coverings having a show surface such as a textile or fabric face material in contacting overlying relation to a polyurethane backing with or without additional structures, layers, backings, and/or the like, as well as apparatus, processes, and/or methods for making such surface coverings, uses for such surface coverings, and/or the like.

  • Patent number: 6491977
    Abstract: The present invention relates to a method and apparatus for forming a layer of blown cellular polyurethane on a textile material, such as a carpet backing. The method includes applying to a textile material a layer of reactive polyurethane forming agents containing a sufficient amount of water or heat-sensitive blowing agent so as to cause chemical blowing of the mixture when heated sufficiently, heating the layer so as to cause chemical blowing of the mixture and applying to the layer during the chemical blowing thereof a pressure of an amount and for a time sufficient to control the blowing of the mixture to a desired degree, the pressure being applied to the mixture continuously from an initial pressure to a final pressure, wherein said initial pressure is greater than the final pressure. Apparatus for performing the process is also disclosed.
