a monofilament or multifilament , high tenacity , polypropylene , polyethylene , propylene based copolymer , ethylene based copolymer , olefin , or fiberglass core yarn is extruded with a coating comprising a mixture of polypropylene , ethylene octane copolymer to form a monofilament yarn . the coating may also include a flame retardant , a pigment , an ultraviolet inhibitor or a lubricant . this yarn is inherently recyclable , and possesses none of the ecological and health concerns associated with commonly used polyvinyl chloride coated yarns . the yarn overcomes the potential health risks , meets flame resistance standards , and ideally replaces pvc products . bonded , woven fabrics employing the yarn are also recyclable , environmentally friendly , and perform as well as fabrics utilizing a pvc coated yarn . such fabric makes an ideal interior window shades , wall coverings , and seating material in typical commercial , residential , or automotive interior applications .
