Abstract: Quilted absorbent pad panel of cluster or ball fiber that contains: Polyester ball or cluster (spherical) fiber; Cotton/Polyester Water and Oil Permeable Fabrics; and attachment means. The fiber is laid out in a “wave”. Next, the “wave” of ball or cluster fiber must be placed and retained between two layers of cotton/polyester water/oil permeable fabric. To retain the fiber between the two layers of cotton/polyester water/oil permeable fabric a unique quilt is created. Unique quilting creates defined closed compartments in which the fiber and cotton polyester fabrics are affixed. Absorbent pad panels are used to absorb and remove oil from the surface of water. Siliconized polyester ball fibers are locked into the sewn compartments of the absorbent pad panels and passively draw the oil from the surface of the water and at the same time repel water so only oil is absorbed in an uncontaminated state.
