Polysiloxane coated polyester fibers blended with other fibers to obtain fibrous mass having more acceptable flame resistance than a mass of unblended polysiloxane coated fibers

摘要

The horizontal burning rate of polyester staple fibers coated with cured polysiloxane is reduced by incorporating small amounts (2 to 20% by weight) of an organic staple fiber that maintains its physical integrity when exposed to a small flame. The preferred fiber is poly(p-phenylene terephthalamide). This has particular application to polyester fiberfill, and articles therefrom.
