The invention provides a method for preparing a 
fluorine-free super-hydrophobic 
textile surface, belonging to the technical field of 
textile treatment. The method comprises the following steps: (a) preparing a 
fog polymerization solution, namely taking methacrylates or acrylic esters as monomers, taking 
divinyl benzene or 
ethylene glycol dimethyl acrylic ester as a cross-linking agent, taking methacryloyloxyethyl 
isocyanate as a curing agent and taking 
dibenzoyl peroxide as an initiator to prepare an organic solution; (b) atomizing the 
fog polymerization solution; and (c) initiating 
precipitation and 
polymerization of 
fog drops. According to the method provided by the invention, an atomized 
monomer solution and almost polymerized 
monomer fog drops are attached on the 
textile surface to control the use amount of the polymerized monomers, and the unattached fog drops can be repeatedly utilized. According to the method, the surface appearance of a 
coating is adjusted by selecting an 
organic solvent, the cross-linking agent and the concentration and the atomizing 
treatment time, and a nano structure of the surface is increased; the 
surface roughness can be improved without using inorganic nano grains.
