Abstract :In this study; pulp was produced with soda-oxygen process by using wheat (Triticum aestevum L.) straw as raw material and this pulp bleached with hypocholoride (H) and peroxyde (P) stages. It was found that crystalline properties of unbleached and bleached pulp samples increased by removing amorphous components. In addition, paper sheets made from unbleached and bleached soda-oxygen pulp and determined their optical properties. Consequently; while crystalline properties of pulp samples was rising with HP bleaching, it was determined that optical properties of paper sheets improved with bleaching.
