The entrance of oil into water as the direct result of industrial activities and the subsequent enviormental polluation has increased enourmously. The means by which this phenmenon can be positively addressed has not only become a challenge for scientific community but also has gained the interest of various scientists involved in many fields. The amount of oil compounds entering the water has increased sharply. This has forced the scientific community to look for varoius mechanisms for separation of water from the oily subtances. In this research, an attempt was weave a special type of fabric (Janus) fabric using a combination of hydrophilic yarns i.e. cotton, viscose with hydrophobic yarns i.e. polyester. This type of dull fabric is capable of separation of oil compounds from water. Such a asymmetric double fabrics fabric can be made using hydrophobic and hydrophilic yarns. The resultant fabric thus is composed of hydrophilic and hydrophobic surfaces. The produced samples were woven using yarns of different finness and warp and weft yarn densities. Samples were examined structurally using photographing technique. Measurement of weight per unit surface area, thickness and the air permeability of the samples were also caried out using established test methods. Separation of oil from water for both the heavy and light oil was carried out using using water and oil columns method. Results confirmed a separation effieciency of more than 90% for both the light and the heavy oil. An additional adsorption test was used for separation of light oil alone. This method yielled to a separation effieciency of more than 85% for the light oil. In order to compare the light oil adsorption capacity together with their oil return rate the reva‎lent tests were performed. Finally the re-useability of the samples were established using continuous cycle of X10 for the water and oil separation test using water and oil columns.
