THERMAL-PROPERTIES OF JUTE CONSTITUENTS AND FLAME-RETARDANT JUTE FABRICS

The thermal behavior of flame retardant jute fabrics impregnated with a diammonium hydrogen phosphate (DAP) and urea (1:2) solution was studied using differential scanning calorimetry (DSC) and thermogravimetric (TG) analysis in nitrogen and air atmospheres. Thermal degradation of flame retardant jute fabrics gradually decreased as chemical add-on increased. Weight loss after pyrolysis decreased, and a much larger residue remained when pyrolysis was complete. The limiting oxygen index also increased with increasing add-on. The ther-mal properties of jute and its main components, holocellulose, hemicellulose, alpha-cellulose, and lignin, were also investigated using DSC and DTG in nitrogen and air atmospheres to interpret the results of thermal analysis of fire retardant jute fabrics.
