| Popis: | In the present context, synthesized zinc borate was demonstrated as a thermal resistant agent by applying it by in-situ method on the cotton fabric wherein zinc borate was synthesized from zinc nitrate and borax. Particle formation and its morphology were confirmed by particle size analyzer, and scanning electron microscopy analysis, respectively. It has been observed that zinc borate-cotton registered the high oxygen index value of 30% against 18% oxygen index of the control cotton fabric. Furthermore, zinc borate treated cotton fabric showed a black colour char and a char length of 25 mm. The extent of heat generated from the treated cotton fabric was also found to be 75% less compared to the untreated cotton fabric. A thermo-oxidative decomposition experiment was performed by thermo-gravimetry analyzer and reported in detail. It was found that the treated fabric recorded more than 40% weight retention at a higher temperature. The surface morphology of the charred mass was also examined to fortify the dehydration mechanism of the treated sample. |
