Claim 5:
6. A method for taking up oil from a water surface using a container configured to receive the oil and a hydrophobic fabric configured to transport the oil, comprising
guiding a first portion of the fabric over a side wall of the container and a first end of the first portion of the fabric is disposed within the container below the level of the water surface, wherein the fabric is designed as a three dimensional spacer textile, which comprises two outer layers spaced apart from one another and spacer threads extending therebetween connecting the outer layers to each other,
bringing a second portion of the fabric into fluid communication with the water surface, wherein said second portion of the fabric is located outside of the container and above the first end of the first portion of the fabric located within the container below the level water surface to create a height difference between the first portion of the fabric and the second portion of the fabric which is a driving force for the transport of the oil or an oily substance into the container, with the fabric configured to adsorb oil so that the oil is transported into the container via the fabric,, wherein a surface of the fabric comprises filament-shaped structures which are designed such that said filament-shaped structures are configured to retain a gas layer on the surface of the fabric under water, which gas layer is replaced by oil when the fabric comes into contact with oil or the oily substance, wherein the spacer threads correspond to the filament shaped structures,
transporting the oil into the container via the fabric and discharging the oil therein.
