Effect of Cationic Starch- CMC Self-assembly Layers on Recovered Fibers of Neutral Sulfite Semi-chemical Pulp and Resultant Paper Properties

Improvement the strength properties of papers made from recycled fibers is of important aims in papermaking industries. Current researches revealed that higher retention of strength induced additives through alternative absorption of polymers having opposite charge is one of promising approaches to...
