In this paper, a type of superhydrophobic cotton textile was designed and prepared. Particularly, it was obtained by coating a type of acrylic-silicone hybrid resin onto the cotton fabric. With self-stratifying character, the cured coating can be formed into two layers, in which the acrylic component in the bottom layer enables polar bond or hydrogen bond linkage with cellulose molecules on the fiber surface, while the amino silicone oil resin on the surface layer acts as a functional part and adds new surface features to the cotton fabric. As a result, the coated cotton fabric displayed superhydrophobicity, with a water contact angle above 150 and a rolling angle less than 8 . The experimental findings indicated that the fabricated textile had adequate mechanical strength to withstand sandpaper abrasion for 20-cycles abrasion by pressing a constant load of 500 g. Additionally, the modified textiles exhibited stable oil-water separation abilities, therefore showing multifunctional properties that have potential applications in many cotton textile surface treatments.
