Abstract: In this paper, Characterization of different unconventional pulping raw materials was carried out. The studies was done in terms of their contents in ash content, cellulose, ethanol–benzene solubility, , hollocelulose, lignin and hot water and 1% soda solubility was carried out. The use of blending of long fibered pulps with short fibered pulp is an important aspect of paper making .Morphological and Chemical nature of hard and soft wood are in many ways different from each other. Soft wood lack certain factors such as drainage, wet strength and press rolls tendency of sticking. To overcome these issues blending plays an important role. Pulp blending can be done in three distinct ways chips blending, pulp blending before beating and pulp blending after beating. Before pulp beating the properties improves the physical strength marginally. But after beating at 1500 revolutions in a PFI helps to improve the strength properties and resulted in increased pulp yields column.
