Jute fiber, a cellulosic and environmentally friendly fiber is treated with low temperature Argon plasma which is an ionized gas and an environment friendly surface modification technique. In the present study jute fiber was treated with low temperature Argon (Ar) plasma at different discharge power levels (50, 75, and 100 W) and exposure times (5, 10, 15 and 20 min.) with a flow rate of 0.2L/min. Ultraviolet Visible (UV-Vis.) spectra of raw jute and plasma-treated jute fibres at various exposure times with different discharge powers were recorded at room temperature in absorption mode using a spectrophotometer in the wavelength range of 200 to 1100 nm. The absorption spectra were recorded both for raw jute and plasma treated jute at various exposure times with different discharge powers. The UV-Vis. spectroscopic analysis reveals that the band gap of jute increases with the increase of discharge power as well as exposure time.
