Multi‐Fiber Blended Needle‐Punched Nonwoven With Oleophilic and Self‐Cleaning Properties for Oil Spill Cleanup

Abstract This study investigates the self‐cleaning, oleophilic, and oil spill clean‐up properties of multi‐fiber blended needle‐punc lf‐cleaning performance of the nonwoven fabrics is influenced by the fiber composition. All samples with a low overall surface energy of 27.65–33.46 mN m −1 , especially those with a reduced polar component, demonstrate superior oil sorption of 13.83–19.45 g g −1 and retention capabilities of 91.11–98.83%. Oil‐to‐water selectivity of 13.66–42.60 and oil removal efficiency of 93.18–97.71% are achieved. The initial oil recovery rate (desorption) during the first desorption cycle (D1) ranges from 78.28% to 79.88%. This recovery rate remains consistently high, between 97.38% and 99.86%, throughout the second to tenth desorption cycles (D2 to D10) for all samples. The findings demonstrate that the blending of multi‐fibers and web arrangement play a critical role in enhancing oil sorption and retention, oil selectivity, oil removal efficiency, reusability and self‐cleaning with statistically significant performance ( p < 0.05).
