Guarding against bloom in FR/UV polypropylene fiber

Displacing polyamide and polyester fibers in the carpet industry with polyp ropylene (PP) has been hampered in a few key market segments. Markets that require resistance to flame and ultraviolet light have been the most diffic ult to penetrate owing to both technical and economical reasons. The migrat ion of additives to the surface (blooming) has been one significant technic al problem. This paper will review progress in the stabilization of flame-r etarded PP fiber and present new advances in this field.
