| Abstract: |
| In order to compare the performance changes of different kinds of Xuan paper after long-term storage， dry heat aging test was carried out on raw and sized Xuan paper to study the changes of surface micro morphology and wear three-dimensional morphology. The static contact angles， adsorbabilities， mechanical properties， and wearabilities of the two Xuan papers before and after dry heat aging were tested and compared. The results showed that before and after dry heat aging， raw Xuan paper had a better adsorption of light ink compared with thick ink； the sized Xuan paper tended to absorb light ink before dry heat aging while after dry heat aging， it preferred to absorb thick ink. The absorbality of raw Xuan paper after dry heat aging was lower than that of before while the sized Xuan paper showed opposite trend， however， mechanical propertied of both Xuan papers increased after dry heat aging. In terms of wearability， raw Xuan paper exhibited reduction after dry heat aging while sized Xuan paper turned out to be more wear-resisting. |
