ABSTRACT:
Oil and oil products are adsorbed with a three-dimensional lattice structure formed by coating individual glass fibers, assembling them and drying them at a temperature of about 150.degree. C. so that the structure will have; sufficient capillarity to pick up substantial amounts of oil and yet the mat will have sufficient structural stability to be stable. The coating is formed by a mixture of hydrophobizing silicone oil and starch (94 to 96% by weight starch to 6 to 4% by weight silicone). The latticework of the fibers and baked silicone oil/starch mixture can be used to pick up oil on a surface and recover oil from the latticework before the latticework is ultimately destroyed in a garbage incinerator.
