    摘要: Textile quality polymeric fibers and thin films that are highly sorbent for organic and other vapors, mists and solutes. The fibers and films comprise a polymeric matrix with a system of interconnecting micropores, and are highly loaded with particulate sorbents such as activated carbon. The fibers and films are manufactured by forming a melt blend of the sorbent particles, the polymer and a selected diluent, spinning or extruding and drawing down the fiber or film, and extracting the diluent. The diluent functions to permit a high spin or extrusion draw down, to permit the subsequent cold drawing of fibers highly-loaded with active carbon, and to permit the fiber or film to be porosified. Optionally, the diluent may be extracted after or before cold drawing, or without any cold drawing. The fibers and films are highly sorbent, are strong and durable and exhibit substantial strength over an appreciable degree of elongation.
