Nanospider™

Nanospider™ is a unique patented technology enabling the production of nanofiber textiles on an industrial scale. This technology was invented at the Technical University of Liberec (TUL), within The Department of Nonwovens, and in a comprehensive partnership arrangement, Elmarco Ltd. has the exclusive global license for developing and commercializing Nanospider™ technology and all relevant applications.

Principle of Nanospider™ technology

Nanospider™ is a modified electrospinning method from polymer solutions. This means that it uses a strong electrostatic field to create nanofibers, and that the input polymers are dissolved in solvents, and are in a liquid form.

The principle of Nanospider™ is based on the discovery that it is also possible to create a Taylor stream from a thin layer of polymer solution. So, unlike other methods, Nanospider™ uses a cylinder, not nozzles or capillaries, to form the fibers. The cylinder is partially immersed in the polymer solution, and, as it rotates, a defined amount of the polymer solution is carried to the top part of the cylinder where Taylor cones - the initiations of nanofibers - are created.

The Taylor streams are formed next to each other, throughout the entire length of the cylinder, resulting in the high production capacity of Nanospider´s™ spinning head. The streams of polymer solutions are then transformed, as the solvent evaporates, and become solid nanofibers before reaching the opposite collecting electrode.
