The invention belongs to the technical field of textiles, and provides a textile with flame-retardant and super-hydrophobic properties and a preparation method thereof. In the method, the cotton fabric is soaked in the chitosan aqueous solution, taken out for drying, then soaked in the flame retardant aqueous solution, taken out and dried; alternately dipping the chitosan aqueous solution and the flame retardant aqueous solution for one time, repeating 1 to 5 secondly, a flame-retardant cotton fabric is obtained; the composite nano-dispersion is prepared by using nano-titanium dioxide, polyvinylpyrrolidone, ethanol, tetraethyl orthosilicate, ammonia water and hexamethyldisilazane; The dispersion is soaked, taken out and dried to obtain a textile with flame-retardant and super-hydrophobic properties. The invention adopts the layer-by-layer self-assembly method to prepare the flame-retardant textile, and the process is environmentally friendly, simple and efficient, and is suitable for large-scale production. |
