Abstract: A solution for forming a graft substrate containing a graft initiator, a catalyst for activating 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.

Abstract: A method for making an air bag by forming a fabric structure of filaments or yarns in the configuration of an air bag, and grafting first and/or second components onto some or all of the filaments or yarns to provide the fabric structure with increased resistance to fraying, filament or yarn pull-out, or distortion during manufacture or use of the air bag compared to non-grafted filaments or yarns. The graft component(s) may be applied to the filaments or yarns prior to, during or after formation of the fabric structure. An air bag material suitable for use in a passive restraint system is also disclosed utilizing grafted fabric substrate provided by the above described method. A passive restraint system utilizing such fabrics is also described.
