textiles with enhanced moisture management can facilitate
sweat transport away from the skin to improve personal comfort. However,
porous materials exhibit low capability of preventing the intrusion
of external liquids, becoming a bottleneck in the design of medical
protective clothing. Herein, a trilayered composite fabric based on
a gradient wettability structure is demonstrated for directional water
transport and resistance to blood penetration. The proposed fabric
shows distinct advantages, including a high water breakthrough pressure
of 2.43 kPa from the external side, an outstanding positive water
transport index (1522%), and an antiblood penetration resistance of
2.71 kPa. Moreover, the fabric shows improved comfort with a high
moisture transmission (320 g m–2 h–1) and desired water evaporation rate (0.36 g h–1). This work addressed the concern of directional water transport
and resistance to blood penetration while providing a comfortable
wearing microenvironment, leading to a promising research direction
for multifunctional medical textiles.
