Starch-fatty complex modified filler for papermaking.

The article presents a study which aims to evaluate the efficiency of a starch-fatty complex modified filler as an alternative method for papermaking. These starch-filler composites are known to improve the filler-fiber bonding in paper including its physical property, filler retention and the sizing effect. Results show that the starch-fatty acid complexes have low solubility, making it easy to be coated on clay surface to modify clay-fiber bonding ability. Researchers also noted that paper strength could increase up to more than 100 to 200 percent by using this method. Furthermore, it has been found that the presence of fatty acids in the complex increases the water-repellant property of the handsheet which can be used to facilitate sizing during papermaking.
