According to the experimental results adipic acid plus sodium chloride appear to be one of the most promising additives among the numerous inorganic and organic compound additives.

The effect of inorganic additives on an's crystal pattern transition is studied by DSC method, and the surface treatment of an is investigated by polymer surfactant.

In order to improve the sizing performance of starch sizes and decrease the dosage of PVA, nanosized inorganic size additives can be used in the formulation of starch solution.
