EFFECTS OF WASH WATER QUALITY ON THE PHYSICAL PROPERTIES OF THREE PAPERS
J. Nelson, A. King, N. Indictor, & D. Cabelli
ABSTRACT—The effects of dry oven accelerated aging on samples of three kinds of paper (Whatman Chromatography #1, Arches Cover Infinity, and Aquabee Newsprint Rough 887-R), washed in three qualities of water (New York City tap water, deionized, and distilled), were observed. Changes in folding endurance, tensile strength, reflectance, color, and pH are reported. Results support findings reported by other researchers that greater purity of wash water is not necessarily beneficial to paper. However, the findings presented here suggest that the acidity of the wash water and the composition of the paper are also factors influencing the effects of the washing treatments.
