- Abstract
- Ignition time measurements on single fabrics and the relative frequency of ignition have been obtained under carfully controlled exposure conditions with convective heating to assess the effect of convective ignition source size and type on the ignition time of cellulosic, thermoplastic and blend materials. The controlled exposure conditions are fabric moisture content, convective source temperature, chemical composition and velocity of incident hot gas jet. Three premixed flame burners of sizes ranging from 12.5 mm to 37 mm diameter, a microburner diffusion flame and a nonradical hot gas jet were used to expose the fabrics under various orientations. Ignition times were found to be independent of the premixed flame ignition source size. Behavior of material when exposed to a convective ignition source was found to depend on the fiber composition and the type of convective ignition source used.
