Latest Patents

John J Allan holds a patent for "Nonwoven webs made from ionomers." This patent discloses a process for extruding fibers from ionomer resins that are not blended with polyolefins, monomers, solvents, or other conventional compounds typically used in connection with processing fibers that contain ionomers. The preferred ionomers are 90% neutralized metal salts of copolymers consisting of at least about 60 to 90% ethylene and from at least about 10 to 40% acrylic acid. Multivalent metal cations can be utilized to introduce cross-linking, which helps control the solubility and swellability of the fibers. The fibers and webs produced can be manufactured through meltblowing and offer a less expensive alternative to superabsorbent powders.
