AI Technical Summary
In existing wet fiber forming processes, the fiber network structure lacks sufficient connectivity in the thickness direction, resulting in low transport efficiency of liquids, gases, or functional media within the material, making it difficult to meet the requirements for mass transfer, penetration, and wetting in the thickness direction.
After constructing the skeleton fiber network, the bridging fibers are driven by pressure difference to penetrate through the skeleton wet sheet along the thickness direction, depositing inside to form bridging support points and connecting channels, thus forming a three-dimensional interconnected fiber microchannel porous network structure.
It improves the connectivity and structural stability of the material in the thickness direction, enhances the transmission efficiency of liquids, gases or functional media within the network, and reduces the risk of local collapse and structural loosening.
