1. Introduction
Textiles such as cotton or polyester fabrics are worldwide used,
however, they are water absorbing and easily stained, which
restrict their practical application. To overcome their disadvantages,
functional modification of textiles to render fabrics superhydrophobicity
and anticontamination has generated particular
academic and commercial interest due to their usage in designing
innovative and higher value textiles for applications in harsh conditions,
such as self-cleaning textiles, water resistant apparel,
antibacterial textiles, and so forth [1e5]. A useful and widely
practical approach to design superhydrophobic surfaces involves
the fabrication of appropriate roughness and low surface energy.
Currently, great efforts have been made to design superhydrophobic
fabrics [6e8], while commercially available superhydrophobic
fabrics are still rare. Waterproof textiles would lose
their non-wettability permanently when applied to a special
chemical environment or physical rubbing. The low durability
hampers their massive applications [8e10].
