This new composite integrates wicking capabilities with reinforcement. Unlike wicking woven geotextiles (WWGs), which rely on deep-grooved fibers for wetting and wicking, the wicking mechanism of WNWGs is primarily based on the microstructure and unique fiber orientation of the nonwoven geotextile component, further enhanced by proprietary chemical treatment to convert the fibers from hydrophobic to hydrophilic. This modification allows WNWGs to exhibit rapid wetting and wicking properties while preserving the large lateral drainage functionality of conventional nonwoven geotextiles. To assess the wicking performance of this material, a series of wicking tests were conducted in both water and saturated soils under controlled temperature and relative humidity. Additionally, contact angle measurements and microscopic analyses using Scanning Electron Microscopy (SEM) were conducted to elucidate the underlying wicking mechanisms.
