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.

Jute fibres are conventionally treated with Jute Batching Oil (JBO), a petroleum based fibre lubricant prior to its processing into yarns. The typical kerosenic smell of JBO seriously affects the consumers' acceptance of jute products particularly value-added hometextiles application. Eventually to invade into hometextiles market, jute products need to avoid such typical odour, though under current practice use of JBO is an integral part of jute fibre processing. To find out an alternate solution, innovative approach of durable aroma/fragrance finishing on jute based textiles has been thought of for masking its bad odour permanently in regards to high-end applications. The present study envisages development of Jasmine oil containing aroma microcapsules from Melamine-Formaldehyde and application of aroma microcapsules on jute-cotton blended fabric in order to impart durable aroma finish. Suitable cross-linker (binder) has also been identified for attaching microcapsule effectively onto ligno-cellulosic textile surface. Effect of partial de-lignification of jute fabric has been examined to improve the effectiveness of binder as well as durability of aroma finishing. Characterizations of aroma microcapsules and washing durability of aroma finish have been carried out using both analytical and human sensory evaluation methods.
