ABSTRACT

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.
