The hygroexpansivity of paper is of particular importance in the paper industry. As paper dimensions become more critical, the problem of hygroexpansivity in paper necessarily becomes more critical. Since the hydrogen ion concentrations (pH) of papermaking water effects the use of fillers, dyes, size, and the quality of the final product, the relationship between hygroexpansivity of paper and the pH of papermaking water is, therefore, an important consideration. Fortunately, the experimental evidence from this project indicates that the pH has little effect upon the hygroexpansion of paper. But rather, this project found the sheet density to have a far greater impact upon the hygroexpansion of paper.
