Physical and mechanical properties of unbleached and bleached bagasse sheets after exposure to Ultra Violet light

摘要

The effect of the exposure of paper samples to UV rays at wave length 254 and 365nm at distances of 15, 30, 45 cm for time up to 100 hours treatment were studied. Two types of paper sheets unbleached and bleached bagasse paper were used in this study. The effect of these treatments on brightness, burst factor, breaking length, tear factor and carboxyl content was carried out. Aging of paper sheets using UV due to decrease in the brightness, burst factor and breaking length, but increase tear factor and carboxyl content.
