- Abstract
- Efficiencies of three flame retardants for cellulose, phosphoic acid, diammonium phosphate, and THPOH ammonia finish, have been evaluated based on the heat release value and the rate of heat release of treated fabrics burning in air measured with the isopetibol calorimeter. The results were compared and correlated with these obtained previously with the bomb-calorimeteric technique. Complete heat balance were obtained for the systems studied by correlation of the calorimetric data and the measurement of combustible gases evolved from the fabric burning in air. The rate of heat release was found to correlate with the flame propagation rate measured at a 45 deg angle. The results from the heat rate and combustible gas measurements were interpretable in terms of existing mechanisms of flame-retardant action.
