The inventor prefers 3 parts of octadecylamine, 2 parts of stearic acid and the finishing agent has the best performance of super hydrophobicity, friction resistance and corrosion resistance.

The inventor finds that the glass resin and the polydimethylsiloxane have a synergistic effect, and the super-hydrophobic, friction-resistant and corrosion-resistant performances of the fabric can be greatly improved by adding the glass resin and the polydimethylsiloxane into a mixed solution of Octadecylamine (ODA) and Stearic Acid (SA), wherein the addition amount of the glass resin in the finishing agent is preferably 2 parts, and the addition amount of the polydimethylsiloxane in the finishing agent is preferably 5 parts.
