- Abstract
- A series of cotton/polyester blended fabrics treated with selected flame retardants containing phosphorus or phosphorus and halogen have been investigated. The flame retardants used were triphenylphosphate, triphenylphosphite and tris(2,3-dibromopropyl)phosphate. The effects of these retardants on the blends were systematically studied by isoperibol calorimetry, oxygen and nitrous oxide indices (OI/NOI) and thermogravimetry (TG). X-ray fluorescence was also used to determine phosphorus and bromine contents of the treated fabrics and of the char. Relative efficiencies of the retardants on the blends and on the component fiber (cotton), were also investigated. Correlation of the results obtained from isoperibol calorimetry, thermogravimetry and X-ray analysis revealed information which may lead to a better understanding of the nature of retardant action in these systems.
