Abstract

The unwanted discharge of oil from different types of reservoirs into sea water has brought many environmental and economic difficulties in the world. In the past, attempts have been made to remove the floating oil from water surface in the oceans using synthetic and natural adsorbents such as polypropylene, cotton, and wool fibers. In the present work, nonwoven fabrics made from the blend of solid and hollow polyester (PET) fibers (0, 25, 50, 75, and 100% hollow fibers) were examined for oil retention and pickup capacities. Four types of oils were used in the experiments. The sorption capacity and oil retention capability of 100%-hollow fiber was found to be superior among the samples tested. The results showed that the replacement of solid fibers with the hollow fibers increased oil pickup capacity and prevent fibers from sinking into deep water. These advantages of hollow fibers are attributed to the higher specific surface area and larger apparent volume of this type of fibers.
