The present world scenario owes for the need of materials which posses more ecological and biodegradable characteristics as well as capable of substituting man-made materials which resulted in the rapid increasing use of natural fibers. In the present investigation, the physico-chemical, thermal, tensile and morphological properties of Prosopis juliflora fibers (PJFs) are presented. Alkali treatment of PJFs was carried out at 2%, 4%, 6% and 8% (w/v) concentrations for a period of 45 min. 6% (w/v) treated PJFs results showed optimal results. These optimally treated fibers showed higher cellulose (74.42 wt. %), lower hemicellulose (2.21 wt. %), lignin (9.11 wt. %), higher crystallinity index (56.64%), crystallite size (15.76 nm), tensile strength (650 ± 6.43 MPa) and better thermal stability.
