Abstract : An anisotropic surface wettability constituted substrates could vouchsafe the diverse intrigue applications from
fluid management, smart textures, flowing control & water harvesting devices, self cleaning textiles to moisture management
systems; in essence, a “Janus fabric” elucidated herein for unidirectional water transportation and breathability of the
structure. Dual phase Janus fabric composite comprises, hydrophobic phase (CA 99.7º ± 1.7º) of Nylon-6/TiO2 nanofibrous
nonwoven mat and hydrophilic phase (CA 30.86º ± 1.5º) of cotton fabric. Heterogeneous wettability is designed by the
deposition of Nylon-6/TiO2 nano fibrous membrane on the cellulosic fabric by electrostatic jetting. Spinning solution
concentration, voltage & flow rate of electrospinning were variegated to optimize the efficacy of nanofibres. The nanofibres
about 150-200nm diameter strewed on cellulosic substrate, were scrutinized in FESEM. Pristine & modified fabrics were
characterized by HR-TEM & FTIR spectroscopy followed by water contact angle perusal. The nanofibrous coated facet of
the cellulosic fabric reveals coherent hydrophobic wettability, at the same time the opposite hydrophilic facet of cotton
conserves its superior moisture engrossing potential (7.4%). Compared to the pristine one, the fabric with hydrophobic face
also shows significant air permeability which corroborated breathability of the substrate. Porous nanofibrous structured
Nylon-6/TiO2 hydrophobic face permits water percolation across the fabric thickness, but when water droplets exposed to the
reverse cellulosic phase, it does not exhibited the identical phenomenon. Instead of penetration, it spreading of water on the
hydrophilic surface was observed. Special wettability incorporated functional surfaces are implicated in various researches,
These substrates may offers many fascinating applications like smart textures, flowing control & water harvesting devices,
self cleaning textiles.
