Resumen:
Una universidad checa ha desarrollado una máquina para producir tejidos nonwoven en 3D con capas de diversos tamaños, desde capas delgadas de 0,5 a 2 mm hasta capas gruesas de 7 a 15 mm, con la posibilidad de incorporar otras capas simultáneamente, como nanohilos, papel, plástico, hojas metálicas, etc. Como producto final se obtienen filtros, aunque también aislantes o sorbentes. La universidad busca socios con el fin de continuar con el desarrollo y establecer acuerdos de cooperación técnica, así como empresas interesadas en la producción bajo acuerdos de licencia.

Licensee sought for a machine producing special 3D textiles
Summary:
A Czech university has developed a machine that produces 3D nonwovens with various sizes of layers; from thin (0,5-2 mm) to thick (7-15 mm). Additional layers (nanowires, papers, plastics, metal foils, etc.) can be added simultaneously. End products include namely filters but can be adapted also for insulations or sorbents. The university is looking for partners interested in further development based on technical cooperation and for companies interested in production under a license agreement.
Description:
A machine developed by the researchers from the Czech university is intended mainly for manufacturing of specialized multilayer - folded 3D fabrics. Such fabrics might be used for producing filters especially for filtering gases and liquids. The unique machine enables production of special products to filter air, water and oil and is in comparison with competitive technologies characterized by higher absorption and therefore higher efficiency. Multiple filter layers also enable control and setting of the filtration process.

In comparison with machines produced by the competitors, the design of the machine allows to insert several different materials such as textile, paper, film (including nanolayers), which leads to gradual layers´ fixation and creation of 3D structure made of these materials. The manufacturing process also allows to add layers containing various powders, including nanopowders.

Products can be manufactured from two or more layers in a single process step. The inner layer may be e.g. plastic foil, aluminium foil, layer of nanofibres etc. In addition, it is possible to reinforce the surface of the product, again, in a single process step.

Principle of technology lies in the vertical stacking of the incoming semi-product (nonwoven textile) and subsequent fixation of the structure. Fixation of the structure is mechanical with possibility to be combined with heat.

As an incoming semi-product (nonwoven textile) can be used, e.g., heat-bonded nonwoven fabrics, needle punched nonwovens (classic and water-jet), weaving nonwovens (containing fleece), spun-bond with a low degree of calendering.

Technical applications of the output products are in the areas of acoustic insulation in the automotive, filtration media and special filters, absorbent cores, seals, vibration control, carpet pads, gaskets etc.

The university offers a licence for manufacturing the machine based on the licensing agreement as the university is not a manufacturer. The university is also looking for partners interested in further development of the machine in order to develop applications in nanofiber, filtration and/or sorbents (application prevent bio-contamination etc.) based on technical cooperation agreement.
Advantages and Innovations:
Innovations:
The novelty of the machine and its key advantage is in the creation of 3D-folded product, which is suitable for further processing into filters with enhanced capacity and durability. Such principle is not yet used by the competitors and is characterized by higher production efficiency and low operating costs. Some types of filters have been already tested in accredited laboratories but the composition of the filter (various filter layers) needs to be adapted for to specific filtration requirements according to the results of other tests.

The end product from the machine can be a filter having favourable value between volume and sorption surface mainly due to the 3D-fabric characteristics such as higher capture efficiency of particles, less fouling and hence longer service - life. Additionally, the machine can be set up in a way that the filter can be composed of different layers, thus the filter may have different parameters for different types of filtration.

Advantages:
- Small build-up floor space
- Production speed is up to 10 m / min
- Product thickness: 4 -7 mm
- Product weight: 300 to 800 g/m2
