Abstract: 
This research down with aim. of study of substitution possibility of bagasse neutral Sulfite semi chemical (NSSC) instead of division of wood pulp for production of newsprint paper in Mazandaran wood and paper complex. Cooking of pulp with use of chemicals of Mazandram wood and paper factory equal to 20 percent (in dry material basis) in 40 minutes time and 170oc heat. After that bagasse pulp refined with (PFI Mill) refiner to 400±25 CSF Freeness and mixture with CMP pulp of Mazandaran and paper factory. Bagasse pulp in ratio 20%, 30%, 40% and 100% of (pure bagasse).
Mixture with CMP pulp of Mazandaran wood and paper factory with 350
±15 CSF Freeness. Bleached long fiber pulp (import) with 550±15 Freeness in 20% level mixture with CMP pulp of factory as blank. One hand sheet with 60 gr/m2 basic weight make from each pulp. Finally: strength properties of hand sheet were determined with used of TAPPI standard. Studies show that, with increasing bagasse pulp, the strength index like Tensile Strength, Burst Strength and Breaking length increased, The only exception was tear Strength, probably the reason of this subject can related to the 20% long fiber pulp in blank sample because long fiber is one of the major factor that influence tear strength and increase it.
