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.
