Anomalous Wetting of Hierarchical Porous Materials Studied by Time-Resolved Imaging and Pore Network Modeling
Water uptake in textiles is measured at yarn scale using 4-D X-ray imaging and neutron radiography showing an anomalous behavior not following a square root time behavior. Water uptake in yarns characterized by a sparse pore network of elongated pores with poor connectivity shows sudden water filling events separated by long waiting times. A multiscale pore network approach is developed allowing to simulate the uptake process and a good agreement with experiments is found. This multiscale approach allows to correctly understand water uptake behavior of complex porous materials at macroscale.
