The microscopic porous structure of paper directly affects its properties. In this study， cotton， hardwood， and softwood pulps were used as raw materials and capillary flow porometer was employed to explore the effects of fiber materials， beating degree， and basis weight on porous structure and permeability of paper. The results showed that with the increase in beating degree and basis weight， the pore size of paper decreased gradually for all fiber materials； the distribution range and peak value of pore size shifted to smaller-size range and permeability also decreased. Compared with the influencing factor of basis weight， beating operation had a greater impact on the size and distribution of paper pore diameter， which further affected the permeability of paper. These results are beneficial to controlling the structure of paper and promoting the design and development of porous paper-based materials. ? 2023 China Technical Association of Paper Industry.
