Oil is principally one of the most important energy sources in the world. However, as long as oil is explored and traorted, there will be risk of spillage into a marine environment. Use of technical textiles, i.e. fibrous beds, is a convient and efficientmeans of oil/water emulsion separation. The main goal of this paper was to investigate the effect fiber parameters of technical textiles used in oil-water separation applications.Both theoretically and experimentally. The analytical model indicated that in the case of woven technical textiles the porosity depends on number of constituting fibers of a yarn (N f ), fiber linear density (D f ), fiber density (? f ) and fabric thickness (T).In non-woven technical textiles the porosity is determined by fabric areal density (m/A), fabric thickness (T) and fiber density (? f ). Eleven types of commercially used technical textiles were prepared. Fiber composition (polypropylene (PP) and polyester (PET), fabric type (woven and/or nonwoven), fabric thickness and fabric areal density were used as independent variables of the experimental design. The oil absorption capacity and oil containment capacity were experimentally obtained for all samples. There found to be a good fitness between experimental data and theoretical results. On the whole, this workfocuses on oil containment and absorption capacity of technical textiles. Both of theoretical predications and experimental results revealed that samples with highest porosity the hasleast oil containment capacity.
