- Abstract
- Burning rate measurements on double layers of the same fabric when one layer has been treat ed with a flame retardant have indicated that certain effects of the retardant can be transferred to the untreated layer. To learn more about the mode and chemistry of this phenomenon, a study of non-flaming combustion of cellulosics has been carried out on mixed systems using thermogravimetric analysis. By arranging to have untreated cotton physically separated from the flame retardant material during heating it was possible to determine that the transfer depends on a chemical process and is most likely the effect of a volatile product generated during heating. Data are presented also showing that rayon containing an alkoxy-phosphazene flame retardant does not transfer its flammability properties to untreated rayon.
