2114131 9304236 PCTABS00020 A combined skirted oil-sorbing boom (10) and oil-sorbing sweep has a buoyant inner core (12) and an oil-sorbent outer core (20) of a spirally wound sheet (15) of polymeric, oleophilic, hydrophobic microfibers. Adhesively bonded to a sheet (15) of the microfibers at the outer face of the outer core (20) is an open-mesh netting (18) of polymeric monofilaments that are fused at their crossings. The netting (18) and the sheet (19) to which it is adhered extend from the outer core (20) to form a depending skirt (22) which acts as a barrier to oil that is being sorbed by the microfibres. The buoyant inner core (12) can be an open-cell foam that sorbs oil slowly, thus supplementing the oil-sorbing capability without significant loss of freeboard.
