Thermal Properties of Jute Constituents and Flame Retardant Jute Fabrics

Abstract

The thermal behavior of flame retardant jute fabrics impregnated with a diam monium hydrogen phosphate (DAP) and urea (1:2) solution was studied using dif ferential 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 thermal properties of jute and its main components, holocellulose, hemicellulose, α-cellulose, and lignin, were also in vestigated using DSC and DTG in nitrogen and air atmospheres to interpret the results of thermal analysis of fire retardant jute fabrics.
