摘要：An improved method is provided for solving the age-old problem of wood-boring marine organisms. Wooden structures which are exposed to sea water can beprotected from shipworm infestation by surrounding the structure with a nonwovenfabric having an effective pore size of less than 200 microns. Nonwoven fabrics of non-cellulosic organic or inorganic fibers are suitable. A self-bonded nonwoven fabric ofpolypropylene fibers is preferred. The fabric has high tensile and tear strengths, goodpuncture resistance, and a small effective pore size. The method may be used on newstructures or old ones that are already infested with marine wood- borers.
