Geotextiles are used commonly in domestic solid waste disposal sites as a protector filter and separator. Because, sand and silt particles included in waste leachate can fill space of gravels which are using as drainage layers. Therefore, the space of the drainage layer is bunged up with particles and it is decompose. This case is not wanted so the usage of the geotextiles has quite importance in waste disposal sites. In general, geotextile lies between waste and drainage layers and it is used to filtration. In order to provide maximum efficiency for geotextiles, it must have some special properties such as high strength, permeability, antimicrobial activity, not affect sunlight UV radiation i.e. In this study, polyester (PES) and Polypropylene (PP) nonwovens were used as substrate for creating functional nanostructures on the fiber surfaces. A pad-dry method was used to deposit different concentration of the components such as functional Poly acrylic, Polystyrene acyrylic and nanoparticles (such as Titanium dioxide (TiO2), Zinc oxide (ZnO)) onto the nonwoven substrates. Air permeability and tensile strength tests were performed on the nonwovens before and after the treatment with the chemical compositions. Sunlight degradation properties were tested after 150 h UV-irradiation. Untreated and chemically treated nonwovens abrasion resistance properties were evaluated after 1000 cycle. According to tests results, a new geotextile filter nonwoven material was suggested for waste areas.
