Jute fibers are an environmental friendly natural fiber which can be used as good alternatives in the reinforcement of composite materials. The physical and mechanical properties of jute fiber are studied. The humidification cum heat treatment is carried out for the jute fiber. The tensile strength measurement was made for the untreated and humidification cum heat treated bundle jute fiber. The tensile strength of untreated and treated bundle jute fibers are 71.7 ± 9.5 MPa and 104.9 ± 8.8MPa respectively. A 45% increase in tensile strength is noticed. The structural organisation in the untreated and treated jute fiber is studied by X-ray fibre diffraction. The tensile strength measurement is carried out for the composite of Paper-Tamarind seed gum and Paper-Tamarind seed gum - Jute fiber and their measured tensile strength are 4.3 ± 0.5 MPa and 6.1 ± 1.2 MPa respectively. The enhancement in tensile strength for Paper-Tamarind seed gum - Jute fiber composite is observed. The environmental friendly biocomposite bags prepared are: Paper-Tamarind seed gum - Jute fiber and Paper-Tamarind seed gum, which can withstand load of 9.0 kg and 6.0 kg respectively. An increase of 50% in the load bearing capacity is achieved by reinforcing jute fibre.
