  • Publication number: 20240084485
    Abstract: The invention relates to a co-filament comprising a first filament and a second filament, wherein the first filament consists of an inorganic substance, wherein the first filament has a glass transition temperature of greater than or equal to 400° C., wherein the second filament consists of a metallic material, the second filament contacting the first filament. Furthermore, the invention relates to a roving, a yarn and a semi-finished product comprising this co-filament, a use of this co-filament and a method for producing this co-filament.

  • Publication number: 20210198811
    Abstract: The invention relates to a method for producing a multicomponent fiber, wherein the fiber is formed from a plurality of filaments, where the filaments each have a core and a thermoplastic sheath, and where the sheath is generated during the production of the filaments by in situ polymerization of monomers or oligomers of the thermoplastic on the surface of the core, and also to multicomponent fibers produced accordingly and to organosheets produced therefrom.

  • Patent number: 10584036
    Abstract: A method for producing an inorganic silica gel fiber or aerogel fiber, comprising the following steps: a) extrusion of a gel, in particular a hydrogel or alcogel, by means of a spinneret directly into a coagulation bath to form at least one filament, b) stretching of the filament in the coagulation bath, c) regeneration of the filament by extraction from the coagulation bath, and d) supercritical drying or freeze drying in order to convert the filament into a silica fiber, in particular an aerogel fiber.
