    Two kinds of super-hydrophobic cotton textiles were prepared via dip-coating cotton textiles with nano-silica suspensions, and the cotton textiles exhibits high contact angle more than 160° and low sliding angle lower than 4°. A friction method was used to evaluate the durability of the as-prepared super-hydrophobic cotton textiles, the results shows that one of the as-prepared super-hydrophobic cottons exhibits better stability property against friction, and its contact angle remained higher than 150° and sliding angle remained lower than 15° after 1000 times friction. SEM analysis shows the reduction of hydrophobic property was resulted from the damage of surface structure during friction cycle.
