Effect of boiling water pre-treatment on the yield, physical, optical and mechanical properties of neutral sulfite semi chemical pulp from wheat straw
In this study, the effect of boiling water pre-treatment on yield, optical, physical and mechanical properties of NSSC (Neutral Sulfite Semi Chemical) pulp from Zagroos wheat straw (Golestan province) was investigated. Chopped wheat straw was pretreated in boiling water for 30 minutes, water to stra...
