Abstract

Surface sizing of historical papers by starch sizing was performed with the aim of investigating the effect of this material on the aesthetic and mechanical properties of historical papers. For this purpose, starch sizing with a weight concentration of 3% were used and pH, colorimetric, angle of contact and tensile strength tests were performed before and after aging of the samples. The results showed that the pH of samples non-sizing and samples containing starch sizing decreased after aging but it is still in the alkaline range. The brightness of the samples was slightly reduced after sizing with starch before and after aging and the color of the samples tends to darken. Tensile strength of paper samples containing starch sizing before and after aging increased compared to samples non-sizing. The results of measuring the angle of contact also showed that starch sizing no effect on increasing the resistance of paper to wetting and does not prevent the surface of the paper from getting wet.
