    Abstract: A fiber that has a unique surface topography in that it contains a plurality of nanohairs extending outwardly from an external surface of an elongate structure of the fiber is provided. To form the nanohairs, a polymer composition is spun that includes organofunctional nanoparticles (e.g., polyhedral organofunctional silsesquioxanes) embedded within a matrix of a base polymer. Despite being initially embedded within the polymer, the present inventors have discovered that, through selective control over the nature and relative concentration of the components of the composition, as well as the method in which the fiber is formed, a substantial portion of the nanoparticles can migrate to the surface of the fiber as it is formed and thus become arranged in the form of nanohairs.

Optionally, the filtration media may be provided with a resin binder and may be grooved and/or pleated.

  • Patent number: 8377308
    Abstract: A dialysate regeneration unit adapted for regenerating a dialysate containing carrier substances comprises a first flow path and a second flow path. The first flow path comprises a first supply unit adapted for adding an acidic fluid to the dialysate flowing in the first flow path, and a detoxification unit located downstream of the first supply unit. The detoxification unit is adapted for removing toxins from the acidified dialysate flowing in the first flow path. The second flow path extends in parallel to the first flow path. The second flow path comprises a second supply unit adapted for adding an alkaline fluid to the dialysate flowing in the second flow path, and a further detoxification unit located downstream of the second supply unit. The further detoxification unit is adapted for removing toxins from the alkalized dialysate flowing in the second flow path.

    Abstract: Nonwoven fibrous webs including a multiplicity of discrete fibers, a population of sub-micrometer fibers having a population median diameter less than one micrometer adjoining the discrete fibers, and a multiplicity of chemically active particulates secured to the nonwoven fibrous web. In some embodiments, more than 0% and less than 10% wt. of the nonwoven fibrous web is made of discrete fibers that are thermoplastic polymeric fibers, and which optionally at least partially melt and coalesce to secure the discrete polymeric fibers to each other. In certain embodiments, at least some of the particulates are bonded to the thermoplastic polymeric fibers. In other embodiments, at least some of the particulates are secured within interstices of the fibrous web, without substantial bonding to the discrete fibers. Methods of making and using such nonwoven fibrous webs are also described.

    Abstract: A filter medium for use in filtering a mobile fluid made from at least a bicomponent fiber. Other fibers, particles, or other materials can also be entrained in the filter medium. The filter medium has a substantial thickness compared to filters of the prior art. The fiber length and diameter dimensions are selected to obtain desired filter characteristics including thickness, basis weight, pore size, filtration efficiency, pressure drop, burst strength, and manufacturing efficiency. Further, a multilayer filter medium can be provided with ease. Each layer can have a different composition, pore size, basis weight, and so forth, thus providing the ability to build multiple functionality into the filter media of the invention.
