Definitions

  • the invention relates to a fabric-like or knitted device for protection against the ingress of dust-like allergens, such as pollen dust and fungal spores, which are transported through the atmospheric air in living and working spaces due to the full-surface attachment to windows and doors
  • pollmose hay fever
  • the allergic reaction to a pollen allergy is usually expressed by reddening and tearing of the eyes (conjunctivitis), sneezing attacks (rhinitis) and irritable cough (bronchial asthma) as early reactions as a late reaction to pollen allergy
  • conjunctivitis reddening and tearing of the eyes
  • rhinitis sneezing attacks
  • irritable cough bronchial asthma
  • Filtration devices that completely remove air from pollen, germs and spores are used in air conditioning technology and in automobiles.
  • the high filtering effect is achieved in DE 3904623 z, for example, by using filter mats, often with multiple layers, made of nonwovens, which due to their fibrous nature Make the filter stage impassable for the allergens mentioned above.
  • the laminate of filter mats is additionally zigzag-folded.
  • such filter mats are not suitable as a protective device in the sense of the proposed invention
  • a further protective device against pollen, germs and spores, which is attached in front of windows, is given in DE 4300422, for example.
  • the attachment of a fabric material as protective device does not take place over the entire surface in front of the window pane, but in the two wedge-like spaces and the rectangular opening at the top of one in a tilted position standing window.
  • the problem of the non-existent, visual transparency of the protection is avoided by this type of attachment, however the protection for a full opening of the window for ventilation purposes has to be removed by swinging open so that there is no longer any protective effect
  • none of the examples cited have the properties of sufficient visual transparency, air permeability and filter effect been able to be achieved in a protective system
  • the object of the proposed invention is to realize the properties of air permeability, visual transparency and sufficient filtering action against pollen in a protection system. It is characteristic that the pollen protection with sufficient filtering action of 70-80% separation efficiency against pollen dust, among other things, in the large range of about 20-40 ⁇ m Adequate renewal of the room air and sufficient visual transparency are particularly important for living and working spaces, the characteristics of air permeability and visual transparency are important, because on the one hand sufficient air exchange properties, on the other hand the view out of the window and the entry of daylight must be enabled Good values for Air permeability, which allows acceptable ventilation of a room, is in the large range of greater than 20,000 m 3 / m 2 / h at a differential pressure of 300 Pa.
  • a sufficient transparency in the sense of the invention is between 20 and 100% transmission Err
  • the properties of sufficient visual transparency and air permeability are made easier by the use of a woven or knitted fabric with a sufficiently large mesh size Window or door opening achieved
  • a similar approach to this topic is also given in DE4414728. Then it is described how an electric field between the allergen and the tissue, which is to be used for filtration, is formed by charging mesh-like fabrics made of synthetic high-polymer fibers. Art the application of the electrostatic charge is not discussed in detail, however, the opposing properties of air permeability and visual transparency to the filtration effect remain undisputed
  • the principle of absorbing a tbo-electric charge is based on the separation of charges, which is done macroscopically by rubbing or separating processes of at least two materials. Decisive for the sign and the amount of the charge are the exit energies W a of the near-surface electrons of the materials, since near-surface electrons emerge from the surface of one material and pass into the other. Consequently, there is an electron deficiency in the surface of one material, which leads to a positive charge on the surface, while the other surface experiences a negative charge due to the excess of electrons.
  • parameters such as temperature, roughness and degree of soiling of the surfaces, as well as the friction or separation speed and air humidity, are included in an electro-electric charging process
  • the prevention of the discharge of electrostatic charging is achieved in that the passage resistance, as well as of the surface resistance of the materials of the order of 10 12 - harbors 10 15 ⁇ , therefore, be for the woven or knitted fabric preferably fibers or on the knitted or woven fabric coatings applied DERS tanden with Oberflachenwi- from 10 12 - 10 15 ⁇
  • Electrostatic charges by charge separation can be done, for example, by quickly removing a polymer film attached to the knitted fabric on one or both sides without air inclusions. Charging is also possible due to the friction of particle-laden air on the protective fabric, by intensively using a household or Indust ⁇ efones, blowers, fans or other types of air with high volume flows
  • the preferred possibility in the inventive sense is the manual rubbing of a polymeric or natural substance on the applied protective knitted fabric after the application in front of the window
  • the application of an electrostatic charge does not occur by applying an external voltage.
  • the maintenance of the charge is not achieved by applying a potential externally, but only by the electrical charge and the setting of the polymer properties. For example, by increasing the air humidity or rain, the charge can be restored after precipitation by drying and then rubbing with the appropriate polymer material. It is also conceivable to dry and recharge in one work step simply by flowing through the protective system with particle-laden air when using a household hair dryer.

Abstract

Utilisation de tissus tissés ou tricotés destinés à être installés devant des fenêtres ou des portes pour la protection contre les allergènes sous forme de poussière tels que les pollens ou la poussière domestique. Cette protection contre les pollens possède un effet de filtrage suffisant contre les pollens grâce à la production d'une charge électrostatique et possède parallèlement des propriétés de transparence visuelle et de perméabilité à l'air suffisantes.
