Abstract
Disclosed are methods of increasing the surface hydrophobicity of the surface of a cellulosic article involving applying a solution of amylose-fatty ammonium salt inclusion complex in water to the article and then optionally applying an alkaline solution to the article to neutralize said amylose fatty ammonium salt inclusion complex to form an insoluble amylose fatty amine inclusion complex. Also disclosed are cellulosic articles produced by the methods.
