ABSTRACT:
The horizontal burning rate of polyester fiberfill coated with cured polysiloxane and/or bonded with a synthetic resin is reduced by incorporating small amounts (2 to 20% by weight) of a synthetic organic filamentary material that maintains its physical integrity when exposed to a small flame. The preferred material is poly(p-phenylene terephthalamide). This has particular application to silicone-slickened polyester staple fibers used for fiberfill, and articles therefrom, but has application also to silicone-slickened polyester filler tow, to resin-bonded polyester staple fiber batts, whether silicone-slickened or not, and to resin-bonded polyester filler tow.
