Comprises various fabrics such as chemical fiber carpets, non-woven wallcoverings, linen, nylon fabrics, colored rubberized fabrics, flannel and the like. These cloths play a considerable role in decorative displays, often a major non-negligible effort in the overall sales space. A large amount of cloth is used for wall surface decoration, partition and background treatment, and a good commercial space display style can be formed.
However, since the decorative cloth is often in a high humidity environment in the process of using the decorative cloth, such as the south return south or the plum rain season, the decorative cloth will be in a state of being wetted for a long time, which not only affects the decorative effect, but also seriously affects the service life of the decorative cloth. In addition, when the decorative cloth is used in various exhibition and display processes, the situation that water is mistakenly scattered on the cloth inevitably occurs, and the cloth is inconvenient to replace immediately at the moment, so that the exhibition effect can be seriously influenced.
At present, the super-hydrophobic material has been widely applied to a plurality of fields of self-cleaning of building material surfaces, water proofing of circuit board surfaces, water proofing and corrosion resistance of metal device surfaces and the like due to the properties of self-cleaning, wetting resistance, water proofing and water blocking and the like. And all obtain good waterproof and anti-wetting effects. Therefore, if a super-hydrophobic coating suitable for various decorative fabrics can be developed, the problems faced by the decorative fabrics can be effectively alleviated.

Therefore, the fabric can quickly drain the water in the inner layer to the fabric in the outer layer, the inner layer keeps dry and comfortable, and the fabric is suitable for manufacturing materials of clothes. However, the outer cloth is not hydrophobic, and the moisture can still wet the surface of the cloth, so that the requirement of the decorative cloth cannot be met.
Patent CN105949499A discloses a method for preparing a super-hydrophobic material, comprising: firstly, finishing a three-dimensional structure on a substrate material by a nanotechnology to improve the roughness of the three-dimensional structure finished by the material; then, coating the material by a low-surface-energy substance through a surface modification technology to finally obtain the super-hydrophobic material. Although the preparation process is simple and the reaction conditions are mild, the nano TiO is used in the first step2The surface roughness of the base material is changed by the materials, and the color of the cloth can be changed for the cloth for decoration, so that the decoration display effect is influenced; in addition, the method adopts a soaking mode to coat the low surface energy, and the fluorine-containing silane wastewater is easy to generate.
