Paper Washing

Quality Control and Optimization of the Conservation Treatments Applied to the Material of the Archives of the Greek Communist Party

“…Four out of five samples exhibited increased strength, compared to the reference samples as a direct result of the treatment. This most probably happens because of the rearrangement of the cellulose chains and the regeneration of the broken hydrogen bonds among them 13 .…”

The Immediate Impact of Aqueous Treatments on the Strength of Paper

“…An extensive survey in the relevant literature indicates that the mechanical behaviour of aqueous treated paper is far from uniform. Most of the researchers report a definite increase in folding endurance 15,40 and tensile energy absorption. Increase in folding endurance has been reported by us previously 41 .…”

“…They also found that contrary to expectation, filter paper and newsprint were protected. Lienardy et al 15 studied the washing of paper.…”

“…The trend was the same for both washing and deacidification, however, whether the differences between the two treatments are statistically significant is difficult to asses as the original data are not available. Lienardy et al 15 measured a decrease in tensile strength for a chemical pulp paper and 3 mechanical woodpulp papers after washing in tap water. Green et al found that Whatman no.2 filter paper suffered a 34-53% loss in tensile strength after washing and aqueous or non-aqueous deacidification.…”

“…The water was changed once after 5 min. 46 ' 47 The sheet was then placed between blotters, under weights, to dry.…”
