Abstract

The invention belongs to the fabric water-repellent finishing and processing field, in particular relates a super hydrophobic cotton fabric and a preparation method thereof. The preparation method of the super hydrophobic cotton fabric is characterized in that the epoxy-functionalized modification is performed to the cotton fiber of fabric, then aminated nano-SiO2 and epoxy-functionalized nano-SiO2 are used to impregnate the cotton fabric in turn so as to increase the surface roughness of the fabric, finally a low-surface-energy material is adopted to perform hydrophobization treatment to the fabric; the contact angle between the prepared cotton fabric and water drops is more than 150 degrees; the method utilizes the covalent reaction of epoxy groups of cotton fabric, amino groups of nano-SiO2 and epoxy groups of nano-SiO2 to ensure the built rough surface to have good fastness; and the built surface has a large number of Si-OHs and epoxy groups so as to facilitate the chemical combination of the low-surface-energy material and the surface, thus the superhydrophobic property of the prepared fabric has excellent stability.
