Abstract:This study analyzed the difference of anti-aging performance of four kinds of Tibetan paper, namely Tibetan Xuela Tibetan paper, Sichuan Dege Tibetan paper, Nangqian Gama Tibetan paper and Nangqian black Tibetan paper. The whiteness, folding endurance and tensile strength of the papers were measured before and after ultraviolet aging. The results showed that the properties of the four kinds of Tibetan paper before aging were quite different, however, the above properties showed a downward trend after aging. Tibetan Xuela Tibetan paper and Sichuan Dege Tibetan paper had good whiteness, folding endurance, retention rate of tensile strength and durability. |
