Moisture absorption and thermal studies of jute fiber with/ without chemical treatments was investigated. If the fibers can retain water, then they will be for better use of biodegradable materials. Chemical treatments on the fiber can be done in order to increase the fiber moisture resistance properties and also to improve the fiber matrix adhesion. Alkali and Silane treatments were done on jute fiber. Nine samples of untreated and treated jute fiber were immersed on distilled water at 19°C – 23°C for 33 days. Moisture absorption studies was performed for 33 days. TGA tests were performed for untreated and treated jute fiber before and after water intake. Before chemical treatment, jute fibers were washed with distilled water. Alkaline and silane chemical treatments were performed on jute fibers. Nine samples of jute fiber untreated, nine samples of jute fiber with alkaline treatment and nine samples of jute fiber with alkaline/silane treatment were immersed in distilled water for 33 days. The specimens were withdrawn for water every 3 days, wiped dry with a tissue to remove surface moisture and then weighed using an electronic balance accurate to 10^-4g to monitor the mass during the aging process. Jute fiber samples with no treatment showed less moisture absorption percent compared to the alkaline and alkaline/silane jute fiber samples. TGA curves of jute fibers samples before water uptake did not show significant change in the decomposition temperature between untreated and treated fibers. TGA curves of jute fibers after being immersed on distilled water for 33 days showed an increment in the decomposition temperature.
