The application belongs to the technical field of textile fabric functional finishing, and particularly relates to a preparation method of super-hydrophobic fabric. The preparation method of the super-hydrophobic fabric comprises the following steps: pretreating cotton fabric by using a zinc ion mixed solution of sodium hydroxide to obtain cotton fabric containing a zinc oxide seed layer; then immersing the cotton fabric containing the zinc oxide seed layer in a mixed solution of a zinc nitrate aqueous solution and a hexamethylenetetramine aqueous solution to obtain a ZnO composite fabric; and finally using the bridging effect of a mercapto silane coupling agent to bond low-surface-energy polydimethylsiloxane and octavinyl octasilsesquioxane to the cotton fabric to obtain the super-hydrophobic fabric. The above method can endow the fabric with excellent hydrophobicity and improve the washing resistance of the hydrophobic effect.

This invention provides a fluorine-free silicone-containing waterproofing agent, its preparation method, and its application, belonging to the technical field of textile functional finishing agents. The fluorine-free silicone-containing waterproofing agent provided by this invention comprises, by mass percentage: 10-15% modified silicone resin, 10-15% modified polysiloxane, 1-5% surfactant, 5-10% organic solvent, and the balance being water. This invention modifies the silicone resin using 2-(trimethylsilane)ethanethiol and 3-chloro-1-propanethiol, introducing shorter-chain hydrophobic groups and polar groups with stronger hydrophobicity. Simultaneously, the modified silicone resin is dissolved using polysiloxane modified with shorter-chain hydrophobic groups, thereby improving the waterproofing and wash resistance of the fluorine-free silicone-containing waterproofing agent.
