Abstract

Surface properties sometimes play a more important role in the function of polymer materials than do the bulk of polymer materials. The surface structure of fibres is of the great importance for the properties of fibres and textiles in processing and use. Because many functions of the polymer materials, e.g. friction, adhesion, adsorption, and liquid penetration, dye ability, hydrophilicity and hydrophobicity related to the topmost layer of the materials. In order to develop textile materials with the desired performance, the surface of fibres is often modified with polymer coatings before use. Water and soil repellency has been one of the major targets for fiber and textile scientists and manufacturers for centuries. To attain limited wettability, in addition to use of a layer with low surface energy, it is necessary to change surface structure in nano-micro scales. These surfaces are known as superhydrophobic surfaces with properties such as lotus leaves. To fabricate superhydrophobic surface on metal, glass, polymer and textiles, many methods and materials are examined to create proper surface roughness and low surface energy, respectivelly. In this review paper, production and properties of superhydrophobic textiles are reported.
