- the liquid supply channels 311 are fed from a reservoir via a pump.
- a central control unit 312 transmits a voltage to the electrical contacts of the ultrasonic nozzles so that the piezo element can perform a mechanical movement. These movements are transmitted to the spray medium.
- the advantage of ultrasonic atomization is the uniform formation and distribution of the droplet size in order to produce thin films in the range of 1 ⁇ m, since the spray medium is atomized without pressure.
- a thin liquid film is formed at the head of the nozzle, in which the piezo element is located, and the vibrations of the piezo create standing waves in the film.
- the peaks of the standing waves detach at sufficiently high vibration amplitudes and form small droplets.
- the droplets are guided onto the substrate via a carrier gas, which is also supplied as a forming gas.
- the main factor influencing the droplet size is the frequency of the ultrasound application.
- the size of the droplets is inversely proportional to two-thirds of the frequency.
- the sulfur in a sulfur-containing proteinogenic amino acid can be converted to a sulfoxide or the hydroxyl group in the side chain of a proteinogenic amino acid to an aldehyde or carboxyl group.
- a chemically The altered amino acid can no longer participate in the construction of vital proteins. Consequently, the microorganism dies.
- Nucleic bases which are contained in the nucleic acids DNA and RNA and are responsible for the genetic information, consist of a basic structure of heterocyclic aromatic amines (purines and pyrimidines) with double bonds. Radicals such as superoxide (hyperoxide) or hydroxyl radicals with single unpaired electrons in the outer electron shell attack the double bonds by filling their outer electron shell with the ⁇ electrons in order to achieve the noble gas configuration. This results in a loss of the double bond system in the ring and the nucleic bases can no longer pass on their information for protein biosynthesis and the replication of the nucleic acids DNA and RNA is interrupted. Here too, the microorganism dies.
- a catalytically supported redox process is triggered at the micro-anode (silver) when it comes into contact with a charged shell of the micro-organism. In this case, too, the microorganisms are destroyed by oxidation. The micro-anode then returns to its original state.
- FIGS. 7A and 7B are examples of proteinogenic amino acids whose functional groups can be oxidatively modified by means of the invention.
- Figure 7C shows, based on the oxidation of adenine (nucleic base in DNA and RNA), basic reactions that are triggered in molecules of a microorganism with the help of the invention, so that proliferation of the microorganism and thus accumulation of multiplied microorganisms is not possible.

- b) Applying the protective layer on the textile surface.
Gemäß einem weiteren Aspekt der Erfindung wird das Textil-Objekts in einem Behältnis für Wasser angewendet. Insbesondere wird das Behältnis für Wasser zumindest aus der Gruppe Behältnis für stehendes Wasser und Behältnis für fließendes Wasser ausgewählt. Das Behältnis für Wasser ist beispielsweise ein Wasser-Boiler zum Erwärmen von Wasser. Denkbar ist aber grundsätzlich jeder Behälter zum Aufbewahren oder zum Führen von Wasser (z.B. Rohr-Leitungssystem).According to a further aspect of the invention, the textile object is used in a container for water. In particular, the container for water is selected at least from the group of containers for standing water and containers for flowing water. The container for water is, for example, a water boiler for heating water. However, any container for storing or carrying water (e.g. pipe system) is conceivable.
Darüber hinaus wird zur Lösung der Aufgabe ein Computer-Programm-Produkt mit einem digitalen Zwilling zur Simulation einer Wirkung der Schutz-Schicht des Textil-Objekts angegeben.In addition, to solve the task, a computer program product with a digital twin for simulating the effect of the protective layer of the textile object is specified.
Unter biologischem Material wird hier ein Material verstanden, das genetische Informationen enthält und sich selbst reproduzieren kann (z.B. Mikroorganismen) oder in einem biologischen System reproduziert werden kann (z.B. Viren). Mit der Schutz-Schicht wird in Gegenwart von Wasser die Ansiedlung von biologischem Material erschwert bzw. unterbunden. So kann sich kein Bio-Film auf der Textil-Oberfläche bzw. auf der auf der Textil-Oberfläche aufgebrachten Schutz-Schicht bilden.Biological material is understood here to mean a material that contains genetic information and can reproduce itself (e.g. microorganisms) or can be reproduced in a biological system (e.g. viruses). The protective layer makes it difficult or impossible for biological material to settle in the presence of water. This means that no biofilm can form on the textile surface or on the protective layer applied to the textile surface.
Eine galvanische Mikro-Zelle (galvanisches Mikro-Element) ist ein elektrochemischer Reaktor. In Gegenwart von Feuchtigkeit entsteht ein für das galvanische Mikro-Element benötigter Elektrolyt.A galvanic micro-cell (galvanic micro-element) is an electrochemical reactor. In the presence of moisture, an electrolyte required for the galvanic micro-element is created.
Feuchtigkeit (Wasser) kann in verschiedenen Medien enthalten sein, z.B. in Luft (Luftfeuchtigkeit) oder in Ausdünstungen (Schweiß), Sekreten und Exkrementen von Lebewesen. Mit Hilfe der Feuchtigkeit in den verschiedenen Medien bilde sich die mikro-galvanische Elemente. So können (mikro-)elektrische Felder entstehen. An der (Mikro-)Kathode werden dabei mit Hilfe von im Wasser gelöstem Sauerstoff reaktive Sauerstoff-Radikale wie Hyperoxide (Superoxide) und Hydroxyl-Radikale elektrochemisch gebildet. Nukleinbasen, die in den Nukleinsäuren DNA und RNA (Ribonukleinsäuren) enthalten und für die genetische Information verantwortlich sind, bestehen aus einem Grundgerüst heterocyclischer aromatischer Amine (Purine und Pyrimidine) mit Doppelbindungen. Die genannten Radikale weisen ungepaarte Elektronen in der äußeren Elektronenhülle auf und greifen die Doppelbindungen der Amine an, in dem sie mit den π-Elektronen ihre äußere Elektronenhülle auffüllen, um die Edelgaskonfiguration zu erreichen. Damit geht ein Verlust des Doppelbindungssystem im Ring einher und die Nukleinbasen können ihre Information zur Proteinbiosynthese nicht mehr weitergeben und die Replikation der Nukleinsäuren DNA und RNA wird unterbrochen.Moisture (water) can be contained in various media, e.g. in air (humidity) or in exhalations (sweat), secretions and excrements of living beings. With the help of the moisture in the various media, the micro-galvanic elements are formed. This is how (micro)electric fields can be created. At the (micro)cathode, reactive oxygen radicals are formed with the help of oxygen dissolved in the water. such as hyperoxides (superoxides) and hydroxyl radicals are formed electrochemically. Nucleic bases, which are contained in the nucleic acids DNA and RNA (ribonucleic acids) and are responsible for genetic information, consist of a basic structure of heterocyclic aromatic amines (purines and pyrimidines) with double bonds.

This is accompanied by a loss of the double bond system in the ring and the nucleic bases can no longer pass on their information for protein biosynthesis and the replication of the nucleic acids DNA and RNA is interrupted.
Beispielsweise verfügt der Mikroorganismus auch über eine proteinogene Aminosäure mit Schwefel. Der Schwefel der Aminosäure kann durch reaktive Sauerstoff-Spezies zu einem Sulfoxid oxidiert werden. Eine Hydroxyl-Gruppe einer SeitenKette einer proteinogenen Aminosäure kann mit Hilfe von reaktiven Sauerstoff-Spezien zu einer Aldehyd- oder einer Carboxyl-Gruppe oxidiert werden. Es wird eine chemisch veränderte Aminosäure gebildet. Die chemisch veränderte Aminosäure kann nicht mehr am Aufbau lebensnotwendiger Proteine teilnehmen. Folglich stirbt der Mikroorganismus.For example, the microorganism also has a proteinogenic amino acid with sulfur. The sulfur of the amino acid can be oxidized to a sulfoxide by reactive oxygen species. A hydroxyl group of a side chain of a proteinogenic amino acid can be oxidized to an aldehyde or a carboxyl group with the help of reactive oxygen species. A chemically modified amino acid is formed. The chemically modified amino acid can no longer participate in the construction of vital proteins. As a result, the microorganism dies.

In a particular case, the anode material is porous silver. A porosity of the silver layer is selected from the range of 10 vol.% to 90 vol.% and in particular from the range of 50 vol.% to 90 vol.%.

Gemäß einer besonderen Ausgestaltung ist das Textil-Objekt aus der Gruppe Sitz-Polster und Textil-Vlies ausgewählt. Die Sitz-Poster und Kopf-Stützen sind beispielsweise in öffentlichen Verkehrsmitteln verbaut. Diese Sitz-Polster und Kopf-Stützen zeigen eine Verunreinigung mit Keimen, weil sie oftmals nicht täglich gereinigt werden, sondern nur bei größeren Zwischen- oder Grundreinigungen, die alle paar Wochen durchgeführt werden. Das Vlies mit der Schutz-Schicht ist beispielsweise an einer Rückseite eines Gegenstandes angebracht, die nicht einsehbar ist.According to a special design, the textile object is selected from the group of seat cushions and textile fleece. The seat cushions and headrests are installed in public transport, for example. These seat cushions and headrests show contamination with germs because they are often not cleaned daily, but only during major intermediate or basic cleanings that are carried out every few weeks. The fleece with the protective layer is, for example, attached to the back of an object that is not visible.
Im Hinblick auf das Verfahren wird zum Anordnen der Schutz-Schicht vorzugsweise ein nass-chemisches Spritz-Verfahren angewendet.

- Mit der Schutz-Schicht werden keine toxischen Verbindungen (z.B. Formaldehyd, Phenole, Hypochlorit, Cuprit, Kupferpyridin oder Silber- Nanopartikel an die Umwelt abgegeben.
- Da die Mikro-Zellen viele Katalyse-Zyklen durchlaufen können, brauchen die antimikrobiellen bzw. Antiviralen Wirkstoffe weder aufgefüllt oder noch ersetzt werden.

Wasser-Speicher oder beliebiges Wasser-Reservoir) oder Wasser-Aufbereitungs-Behälter (z.B. Wasser-Boiler) und in Apparaturen mit Wasser-Kreisläufen oder mit stehendem Wasser (z.B. private oder öffentliche Duschen). So wird beispielsweise die Ausbreitung von Legionellen wirksam verhindert.

- With the help of the protective layer, the formation of a bio-film (fouling) on the textile surface can be inhibited.
- With the protective layer, no particles (e.g. ions or nanoparticles) are released into the environment.
- The protective layer prevents any toxic compounds (e.g. formaldehyde, phenols, hypochlorite, cuprite, copper pyridine or silver nanoparticles) from being released into the environment.
- Since the micro-cells can undergo many catalytic cycles, the antimicrobial or antiviral agents do not need to be replenished or replaced.

This effectively prevents the spread of legionella, for example.
- Textile objects in humidifiers and air washers that use water, for example, to remove suspended particles such as dust, pollen, tobacco smoke and odor molecules from the sucked-in room air via rotating rollers or plates.
- Other systems (e.g. fog generators or fog fountains that atomize water into droplets or aerosols.

So werden die Ceroxide aus einer niedrig molaren (0,1 bis 0,5 Mol/Liter) Cer(III)-Nitratlösung mit einem basischen Elektrolyten, wie 1 M Kaliumhydroxidlösung, 1 M Natriumhydroxidlösung oder Ammoniak bei pH 13, als Ce (OH)3 gefällt:
Anschließend wird das Ce (OH)3 bei 110°C getrocknet und in Ce2O3 umgewandelt:
Mangandioxid wird aus einer niedrig molaren (0,01 bis 0,05 Mol/ Liter) Kaliumpermanganat- Lösung und einer niedrig molaren (0,015 bis 0,075 Mol/ Liter) Mangan(II)- Nitrat- Lösung bei pH 8 bis 9 gebildet:
Vor der Reaktion der beiden Lösungen wird die Mangan(II)-Nitrat-Lösung auf pH 8 eingestellt entweder durch Zugabe von Ammoniak oder durch Zugabe einer basisch wirkenden Aminosäure wie L-Lysin. Andere basische Aminosäuren wie L-Histidin oder L-Arginin können ebenfalls verwendet werden.Before the two solutions react, the manganese(II) nitrate solution is adjusted to pH 8 either by adding ammonia or by adding a basic amino acid such as L-lysine. Other basic amino acids such as L-histidine or L-arginine can also be used.
Über eine Komproportionierung wird aus Mn +7 und Mn +2 Braunstein hergestellt:
Bei der Reaktion wird das Mangan(II)-Salz vom Kaliumpermanganat zu Mangan(IV)-Oxid oxidiert und das Kaliumpermanganat wird vom Mangan(II)-Salz zu Mangan (IV)- Oxid reduziert. Mangan(IV)-Oxid stammt sowohl aus dem Reduktionsmittel (Mangan(II)-Nitrat) als auch aus dem Oxidationsmittel (KMnO4).In the reaction, the manganese(II) salt is oxidized by the potassium permanganate to manganese(IV) oxide and the potassium permanganate is reduced by the manganese(II) salt to manganese(IV) oxide. Manganese(IV) oxide comes from both the reducing agent (manganese(II) nitrate) and the oxidizing agent (KMnO 4 ).
Mangandioxid ist in wässrigen und basischen Lösungen unlöslich und schlägt sich als Präzipitat auf die zu beschichtende Oberfläche nieder. Anschließend wird das abgeschiedene Präzipitat 24 Stunden bei 110°C unter Luftsauerstoff in einem Ofen getrocknet.Manganese dioxide is insoluble in aqueous and basic solutions and forms a precipitate on the surface to be coated. The precipitate is then dried in an oven at 110°C under atmospheric oxygen for 24 hours.
Silber wird aus einer niedrig konzentrierten (5g/Liter bis 25g/Liter) Silbernitrat-Lösung und Glucose-Ascorbinsäure- Lösung gebildet. Dabei wird das Silbernitrat durch die Glukose und die Ascorbinsäure zu Silber reduziert und fällt als elementares Silber aus:
Alle genannten Lösungen können durch Aufsprühen über normale Lackierpistolen mittels Druck-Gas oder durch spezielle Düsenformen über Ultraschall auf dem Textil-Vlies appliziert werden. Jeder Partner des antimikrobiell wirkenden Systems wird aus zwei entsprechenden Elektrolyten gebildet, die getrennt über zwei Düsen simultan auf das Textilvlies gesprüht werden, damit die jeweiligen bakteriziden und viruziden Partikel in situ gebildet werden.All of the solutions mentioned can be applied to the textile fleece by spraying them using normal paint spray guns with compressed gas or using special nozzle shapes using ultrasound. Each partner of the antimicrobial system is made up of two corresponding electrolytes, which are sprayed separately onto the textile fleece simultaneously using two nozzles so that the respective bactericidal and virucidal particles are formed in situ.
Für die Textilien und Vliesstoffe, die in langen und breiten Bahnen vorliegen, ist bei der simultanen Applikation zweier Elektrolyte das Aufsprühen über Ultraschall vorteilhaft. Man kann mehrere Düsen in einer Reihe sowohl in der Breite als auch in der Tiefe anordnen (vgl.
Anschließend folgt in der dritten Reihe 305 die Auftragung von Kaliumpermanganat-Lösung und in der vierten Reihe 306 wird der Reduktor für Kaliumpermanganat die Mangan-(II)- Nitrat-Lösung aufgetragen. Dabei stehen die Reihen 301 und 302 sehr nahe aneinander. Die Cer-(III)-Nitrat-Lösung und der Ammoniak werden gleichzeitig gespritzt, damit das Ceroxid in situ gebildet werden kann.This is followed by the application of potassium permanganate solution in the
Das Gleiche gilt auch für die Bildung von Mangandioxid in der Reihe 305 und 306. Auch die Reihen 305 und 306 stehen sehr eng aneinander, so dass Kaliumpermanganat und Mangan (II)-Nitrat simultan gespritzt werden können. Nach dem Trocknen mit Infrarotstrahler 307 oder Heißluft-Gebläse 308 an Luftsauerstoff bei 110°C über mehrere Stunden sind die langen und breiten Textil-Vlies- oder Vlies-Bahnen fertig und können der weiteren Verarbeitung zugeführt werden, z. B. als Futtermaterial für die Polstersitze.The same applies to the formation of manganese dioxide in
In alternativen Anwendungen sind Textil-Objekte in Form von Kleidung, speziell in Form von medizinischer Kleidung oder in Form von Masken mit Nasen-Mund-Bereich oder in Form von Textil-Vliesen in Filteranlagen vorgesehen.In alternative applications, textile objects in the form of clothing, especially in the form of medical clothing or in the form of masks with a nose-mouth area or in the form of textile fleeces in filter systems are intended.
Vorteil der Ultraschallzerstäubung ist die gleichmäßige Bildung und Verteilung der Tröpfchen- Größe, um dünne Filme im Bereich von 1µm herzustellen, da das Spritzmedium ohne Druck zerstäubt wird. Am Kopf der Düse, in dem sich das Piezoelement befindet, wird ein dünner Flüssigkeitsfilm gebildet und durch die Vibrationen des Piezos entstehen im Film stehende Wellen. Die Spitzen der stehenden Wellen lösen sich bei ausreichend hohen Schwingungsamplituden ab und bilden kleine Tröpfchen. Die Tröpfchen werden über ein Trägergas auf das Substrat geleitet, welches zusätzlich als formendes Gas zugeführt wird. Der hauptsächliche Einflussfaktor der TröpfchenGröße ist Frequenz der Ultraschallanwendung. Die Größe der Tröpfchen ist umgekehrt proportional zu zweidrittel der Frequenz.Zum Beispiel kann der Schwefel in einer schwefelhaltigen proteinogenen Aminosäure zu einem Sulfoxid oder die Hydroxylgruppe in der Seitenkette einer proteinogenen Aminosäure zu einer Aldehyd- oder Carboxylgruppe oxidiert werden. Ein derart chemisch
veränderte Aminosäure kann nicht mehr am Aufbau lebensnotwendiger Proteine teilnehmen. Folglich stirbt und der Mikroorganismus.The advantage of ultrasonic atomization is the uniform formation and distribution of the droplet size in order to produce thin films in the range of 1 µm, since the spray medium is atomized without pressure. A thin liquid film is formed at the head of the nozzle, in which the piezo element is located, and the vibrations of the piezo create standing waves in the film. The peaks of the standing waves detach at sufficiently high vibration amplitudes and form small droplets. The droplets are guided onto the substrate via a carrier gas, which is also supplied as a forming gas. The main factor influencing the droplet size is the frequency of the ultrasound application. The size of the droplets is inversely proportional to two-thirds of the frequency. For example, the sulfur in a sulfur-containing proteinogenic amino acid can be converted to a sulfoxide or the hydroxyl group in the side chain of a proteinogenic amino acid to an aldehyde or carboxyl group. Such a chemically
The altered amino acid can no longer participate in the construction of vital proteins. Consequently, the microorganism dies.
Nukleinbasen, die in den Nukleinsäuren DNA und RNA enthalten und für die genetische Information verantwortlich sind, bestehen aus einem Grundgerüst heterocyclischer aromatischer Amine (Purine und Pyrimidine) mit Doppelbindungen. Radikale, wie Superoxid (Hyperoxid) oder Hydroxylradikale) mit einzelnen ungepaarten Elektronen in der äußeren Elektronenhülle greifen die Doppelbindungen an, in dem sie mit den π- Elektronen ihre äußere Elektronenhülle auffüllen, um die Edelgaskonfiguration zu erreichen. Damit geht ein Verlust des Doppelbindungssystem im Ring einher und die Nukleinbasen können ihre Information zur Proteinbiosynthese nicht mehr weitergeben und die Replikation der Nukleinsäuren DNA und RNA wird unterbrochen. Auch hier stirbt der Mikroorganismus ab.Nucleic bases, which are contained in the nucleic acids DNA and RNA and are responsible for the genetic information, consist of a basic structure of heterocyclic aromatic amines (purines and pyrimidines) with double bonds. Radicals such as superoxide (hyperoxide) or hydroxyl radicals with single unpaired electrons in the outer electron shell attack the double bonds by filling their outer electron shell with the π electrons in order to achieve the noble gas configuration. This results in a loss of the double bond system in the ring and the nucleic bases can no longer pass on their information for protein biosynthesis and the replication of the nucleic acids DNA and RNA is interrupted. Here too, the microorganism dies.
An der Mikro-Anode (Silber) wird bei Kontakt mit einer geladenen Hülle des Mirko-Organismus ein katalytisch unterstützter Redox-Prozess ausgelöst. Auch in diesem Fall werden die Mikroorganismen oxidativ zerstört. Die Mikro-Anode kehrt dann wieder in ihren Ausgangszustand zurück.A catalytically supported redox process is triggered at the micro-anode (silver) when it comes into contact with a charged shell of the micro-organism. In this case, too, the microorganisms are destroyed by oxidation. The micro-anode then returns to its original state.
