  • Patent number: 5407728
    Abstract: A solution for forming a graft substrate containing a graft initiator, a catalyst for activating or regenerating the graft initiator, a first component of water dispersable polymer and a second component of a monomer, each of which includes a functional group for reaction with an activated site on the substrate for grafting thereto and water. A method for grafting at least one of the components to a fiber, yarn or fabric substrate is also disclosed wherein increased flame retarding and yarn integrity is achieved while simultaneously allowing control of fabric porosity. This method does not significantly reduce fabric pliability as compared to uncoated fabric. Furthermore, the graft component may be selectively applied polymer to produce a preferred porosity range or a cutting pattern for the fabric substrate. A fabric, a portion of which includes a graft component or components thereon, forms another embodiment of the invention.

  • Patent number: 5395868
    Abstract: Coating solution for papermaking fabrics that includes as its primary components polytetrafluoroethylane, urethane copolymer and polyacrylamide. The coating composition is prepared in a solution, coated on the fabric and cured. A fabric thus treated has permanent anti sticking properties against pressure sensitive adhesives, pitch from wood pulp, ink deposition and the like.

  • Patent number: 5207873
    Abstract: A papermaking fabric having permanent resistance to adhesion of contaminants, and a method to make such a fabric by treatment of a papermakers fabric with a solution having as its primary components tetrafluoroethylene, urethane copolymer and polyacrylamide. The treatment, prepared in a solution, is coated on the fabric and cured to impart permanent anti-sticking properties to the fabric.
