“…It is worthy to note that the capillary force is generated by the Laplace pressure whose magnitude is given by the following Young–Laplace equation: L a p l a c e .25em p r e s s u r e = 4 γ cos nobreak0em.25em⁡ θ D p o r e where γ represents the droplets’ surface tension, θ denotes the advancing water contact angle (WCA) on the capillary inner surface of the membrane, and D pore refers to the pore size of the fibrous membrane. Consequently, the reduction in pore size and increased surface wettability can amplify the capillary force, propelling the movement of liquid water through the layered porous membranes, where the pore size varies from the large to the small. − …”

Specialty textiles with excellent moisture-wicking technology are essential for satisfying personal comfort, coupled with the widespread concern that conventional functional textiles put a huge strain on the environment due to their nondegradable nature. Therefore, we demonstrated a simple strategy to prepare biodegradable trilayered porous membranes based on a conventional papermaking process by assembling two raw materials with different wettabilities, plant fibers (PF), and poly (lactic acid) (PLA), constructing trilayered PF/(PF-PLA)/PLAnw membrane with wettability gradients and pore gradients, which allow the water to flow unidirectionally from the hydrophobic layer to the hydrophilic layer through capillary forces and eventually evaporate as the air flows. The resultant porous membranes exhibit a desirable accumulative one-way transport capacity (AOTC) of 993%, a remarkable water evaporation rate of 0.52 g h–1 ,and an excellent tensile strength of 7.26 kN m–1, providing a brand-new insight into the design of biodegradable functional fabrics and serving as a green alternative for sweat-wicking fabrics to alleviate environmental pressure.
