    摘要: The present invention relates to a cellulose carbamate spinning solution, the cellulose carbamate being dissolved in an ionic liquid. The invention relates furthermore to a method for the production of nonwovens in which the cellulose carbamate spinning solution is pressed through the holes of a nozzle bar and stretched by a multiple by means of an air flow. The formed fiber curtain is laid on a perforated conveyer belt, washed and dried. Likewise, the invention relates to nonwovens of this type and also the use thereof.

    摘要: The present invention relates to a process of making biodegradable and/or bioabsorbable biomaterials and keratin nonwoven fibrous articles by electrospinning fibers from a blend of biomaterials and keratin dissolved in organic solvents includes generating a high voltage electric field between oppositely charged biomaterials and keratin fluid in a syringe with a capillary tip and a metallic collection roller and causing a jet to flow to the roller as solvent evaporates and collecting fibrous membranes or scaffolds on the roller. Keratin increased the cell affinity of biomaterial scaffolds which have potential medical applications.

    摘要: Nanofibers are formed from a polymer material by rotating a conductive rotating container having a plurality of small holes while supplying a polymer solution formed by dissolving a polymer material in a solvent into the rotating container, charging the polymer solution discharged from the small holes of the rotating container by charging means, and drawing the discharged filamentous polymer solution by centrifugal force and an electrostatic explosion resulting from evaporation of the solvent. The nanofibers from this production step are oriented and made to flow from one side toward the other side in a shaft center direction of the rotating container by a reflecting electrode and/or blowing means, or those nanofibers are deposited, to produce a polymer web. The nanofibers and the polymer web using these nanofibers can be produced uniformly by a simple configuration with good productivity.

    摘要: Process of manufacturing spun-bonded fabric, using naturally crimped filaments, whereby the filaments are passed through a stretching unit and finally through a diffusor. The filaments are thereupon layered on a layering device, as crimped filaments. The layered filaments together with the layering device are passed through a solidifying device in which the filaments are solidified by means of a fluid.
