Abstract：
:In order to maximize value and minimize waste, carboxymethyl cellulose (CMC) and carboxymethyl starch (CMS) was synthesized via solvent method using cassava residue as raw material. The alkalization time, etherification temperature, the amounts of reactants and the alkali boiling pretreatment which influence the carboxymethylation degree of cassava residue were investigated. Additionally, we studied the variation of Cobb values and ring crush index of the corrugated medium after surface sizing with the optimized carboxymethylated cassava residue. The optimum sample and starch with the mass ratio of 1:10 were mixed to prepare the sizing agent with a concentration of 6%, which was sized on the corrugated medium with a basis weight of 112 g/m2. The Cobb value and ring crush index of the sized-corrugated medium was 26.3 g/m2 and 8.1 N·m/g, which increased by 36.3% and 32.8% respectively compared with the reference one sized with pure starch solution.
