The effects of wheat straw fiber having fiber length (2mm and 6mm) and alkali treatment in polypropylene (PP) matrix were investigated to produce environment friendly composites. Wheat straw fibers were varied at 10%, 20% and 30% wt% in the composite. Wheat straw fibers (treated and untreated) were characterized using Thermo Gravimetric Analysis (TGA), X-ray diffraction (XRD) and Fourier Transform Infrared Spectroscopy (FT-IR). Crystallinity of treated wheat straw fiber was found to increase by 9.2%. FT-IR showed lignin content decreased from 17.7% to 9.3% whereas cellulose content increased from 35.9 to 45.8% after alkali treatment. Mechanical properties, composite of treated fiber having 2 mm length showed maximum increase in flexural and tensile modulus by 40% and 49% at 30% fiber loading.
