  • Publication number: 20150104642
    Abstract: A graphene composite fiber includes graphene sheets and a polymer for aggregating the graphene sheets together. The polymer includes either or both of a hyperbranched polymer and polyvinyl alcohol. The graphene sheets and the polymer are stacked on each other to form a layered structure, and the graphene sheets are regularly arranged along an axial direction of the graphene composite fiber. In a production method of the graphene composite fiber, a graphene oxide is used as a raw material, which significantly improves tensile strength of the graphene composite fiber. Addition of the polymer provides good tenacity for the composite fiber. In a spinning process, rotated coagulant is used to increase a tensile force of a gelatinous fiber, so that the gelatinous fiber has high orientation and tacticity, thereby significantly improving strength of an obtained solid fiber. The final reduction process restores electrical conductivity of a graphene fairly well.

    Abstract: A non-woven product containing organic and/or mineral particles has a volume density less than 1 and has at least two layers of synthetic fibers or filaments superposed in the Z direction perpendicular to the XY plane of the product, having undergone at least one needling operation, where the non-woven product integrates particulate feedstocks of mineral and/or organic particles distributed in a monomodal or multimodal manner in the product and at least partially coated or encapsulated by binding material that can point-connect the filaments or fibers to one another. At least one population or fraction of organic and/or mineral particles, has a size such that: 3×(?{square root over (SMf)})3?v, preferably 5×(?{square root over (SMf)})3?v, where SMf corresponds to the mean cross-section of the fibers or filaments that form the layers, and v represents the mean individual volume of the organic or mineral particles.

  • Publication number: 20150090658
    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.

  • Publication number: 20150044463
    Abstract: A fiber is provided that has been thermally drawn from a fiber preform, having a longitudinal-axis length and including at least one core that has a longitudinal core axis parallel to the longitudinal axis and internally disposed to at least one outer fiber cladding material layer along the fiber length. The fiber is fed through a localized heating site having a heating site temperature, T, that is above a melting temperature of the fiber core, with a feed speed, ?f, that melts a portion of the fiber core at the heating site, causing molten droplets to pinch off of fiber core material, one droplet at a time, with a time period of molten droplet formation set by the fiber feed speed, ?f. The fiber is fed through the localized heating site to move the molten droplets out of the heating site and solidify the molten droplets into solid in-fiber particles.
