Özet

An investigation of the effect of sodium metasilicate pentahydrate and urea (in brief SMSPHU) impregnation on the thermal-oxidative stabilization of eco-friendly jute fibers was undertaken. SMSPHU integration followed by the oxidation process in the air caused major physical and structural changes. The physical and structural characterizations of the jute samples were performed employing flame test, linear density, volume density, fiber thickness, X-ray diffraction (XRD), thermogravimetric analysis (TGA), and infrared (IR) spectroscopy analysis. Development of thermal stability in the jute samples was observed from the thermogravimetric measurements. The SMSPHU impregnated jute fibers oxidized at 245 degrees C for 175 min by multistep annealing approach showed the highest value of carbon yield of 57.65% at 1000 degrees C. The infrared spectroscopy and X-ray diffraction outcomes showed continuous decrystallization reactions because of the hydrogen bond (H-bonds) scission by progressing stabilization period. The development of the carbonyl (C = O) group was specified by the infrared analysis, which is because of the occurrence of dehydrogenation reactions and oxidative cross-linking reactions. The results suggest that the jute fibers with a stabilization period of 175 min by multistep annealing approach at 245 degrees C are expected to resist high carbonization and activation temperatures.
