The　technologies　of　superhydrophobic　finishing　normally　involve　harmful　reagents　such　as　fluorine-containing　materials　and　organic　solvents.　Non-toxic,　environmentally　friendly,　and　large-scale　applicable　preparation　methods　for　superhydrophobic　finishing　remain　a　considerable　challenge　towards　practical　applications.　In　this　paper,　we　proposed　a　superhydrophobic　foam　finishing　method　with　a　low　liquid-carrying　rate.　This　finishing　solution　is　totally　water-based　without　the　use　of　any　organic　solvents　or　fluorine-containing　materials.　Based　on　the　characteristics　of　low　liquid-carrying　rate,　this　method　can　save　nearly　60%　of　the　solution　consumption.　In　addition,　multifunctional　superhydrophobic　fabrics,　such　as　hydrophobic　patterns　and　Janus　fabrics,　can　be　fabricated　by　this　foam　finishing　method.　Excellent　properties　such　as　superhydrophobicity,　anti-fouling,　and　directional　water　transportation　could　be　achieved　by　controlling　the　amount　of　superhydrophobic　foams.　Compared　with　other　finishing　technologies,　the　foam　finishing　method　has　the　advantages　of　being　facile,　rapid　in　preparation,　environmentally　friendly,　and　applicable　for　large-scale　production.　This　technology　could　be　applied　on　various　substrates　and　achieve　rapid　preparation　for　superhydrophobic　surface,　Janus　surface,　and　double-sided　heterochromatic　superhydrophobic　surfaces.
