Definitions

  • the invention relates to the use of textured thread material in textile fabrics, which acts as a pollen filter to protect against the ingress of dust-like allergens, such as e.g. Pollen dust and fungal spores can be used in living and work spaces thanks to the full-surface attachment in front of windows and doors.
  • dust-like allergens such as e.g. Pollen dust and fungal spores
  • pollinosis hay fever
  • hay fever ie the allergic reaction of the mucous membranes of the eye as well as the upper and lower respiratory tract with bee pollen and other airborne allergens
  • the allergic reaction to a pollen allergy usually manifests itself as reddening and tearing of the eyes (conjunctivitis), sneezing attacks (rhinitis) and irritable cough (bronchial asthma) as early reactions.
  • a late reaction to pollen allergy e.g. Known eczema or eczema on the skin.
  • Pollen allergies are triggered by the hereditary factors of wind-flowering plants, which, in contrast to insect-flowering plants, use the air movement to transmit their male hereditary factors. For this reason, pollen from wind-flowered plants is generally smaller than that from insect-flowered plants. Frequently occurring sizes are in the range of 15 - 50 ⁇ m.
  • Well-known examples of wind-flowering plants that trigger pollen-allergic reactions are birch, hazel, mugwort and a number of types of grass.
  • Filtration systems that remove air from pollen, germs and spores are used, for example, in air conditioning technology and in automobiles.
  • the filter effect is described in DE 3904623 e.g. achieved by using multi-layer filter mats made of nonwovens.
  • the laminate of filter mats is additionally zigzag folded.
  • the filter effect against pollen is achieved by the fibrousness of the nonwovens, since the spaces between the fibers are smaller than the pollen to be filtered.
  • a window protection device against pollen, germs and spores is e.g. specified in DE 19722326.
  • a fleece is applied as a protective device, but not over the entire area in front of the window pane, but in the two wedge-like spaces and the rectangular opening at the top of a window in a tilted position.
  • the filter is designed as a full-surface system to be installed in front of the window.
  • the arrangement consists of a shrink film to be attached in front of the window, which has a recess in one area into which a filter fleece is glued by means of a double-sided adhesive tape.
  • the filter consists of a nonwoven fabric made of plastic fiber with an electrostatic charge.
  • the fleece is additionally reinforced by a scrim.
  • the filter effect is achieved by a fabric made of microfilaments with spacing of the filaments in the order of magnitude of 30 ⁇ m.
  • Textile fabrics such as woven fabrics, knitted fabrics and knitted fabrics often offer advantages in terms of mechanical stability compared to nonwovens. For this reason, nonwovens have to be consolidated in a further step in the manufacturing process.
  • a disadvantage of using nonwovens is also the less favorable air permeability and visual transparency with the same basis weight, for example in the order of 50 to 100 g / m 2 .
  • irregularities in the transparency over the fleece surface often occur due to which they are additionally processed by combing processes. The problem of visual transparency was therefore avoided in some of the pollen protection systems described by the special type of attachment to the window.
  • textile fabrics describes the totality of all possibilities to represent textiles from thread material through common surface formation processes such as knitting, knitting or weaving, without wishing to commit to a technique here. Fundamentals about textile surface formation processes can be researched in Alfons Hofer: “Fabrics 2", 1983, German specialist book publisher or “Warp knitting practice”, Issue 4, 1970, pages 19-20, warp knitting technologies.
  • the texturing of thread material is primarily used for textile fabrics made of synthetic fibers such as polyester or polyamide in order to give the synthetic fibers a character similar to natural fibers.
  • man-made fibers When spun into yarns, man-made fibers differ from natural fibers in the length of the filaments to be spun.
  • the filament length of natural fibers is much shorter than that of man-made fibers and is only a few centimeters.
  • short filament lengths are spun into yarns and threads, such as cotton, the protruding filament ends give it a bulky and pleasant grip.
  • continuous filaments are used for man-made fibers, which have a parallel position to each other after spinning to the yarn and give the yarn a smooth, unnatural touch.
  • the texturing of thread material from artificial continuous filaments can be carried out, for example, by the deformation of the filaments from their parallel position by torsion or bending with subsequent heat setting.
  • An example of this is the so-called false wire procedure [Basics of textile finishing ", 13th revised edition, German specialist book publisher 1989].
  • Textile fabrics made of man-made fibers such as polyester with textured thread material are often used for clothing purposes because of their pleasant haptics, for example as a front fixation in high-quality outerwear.
  • Use as pollen protection in front of window areas and door openings as well as for other ventilation entrances is a new field of application and should be protected.
  • the use of a textile fabric with textured threads offers the advantage over the cited approach of achieving a filtration of pollen through the small distance between warp and weft threads in fabrics that the filaments of the textured thread narrow the distance between the threads and thereby distances come about between the filaments of two adjacent threads and / or the filaments of the textured thread, which are impassable for pollen.
  • the bulging of the threads causes the two-dimensional fabric to expand into the third dimension.
  • the textured threads mean on the one hand a longer flow path means a longer contact time of the air with the filter material and on the other hand an increase in the filter surface, which leads to improved filter properties.
  • the object of the proposed invention is to provide a woven or knitted fabric which can be used as a pollen protection over the entire area of windows and doors.
  • the invention relates to a textile fabric, preferably a woven or knitted fabric, in which at least one textured weft thread is inserted.

  • Textured weft threads are inserted into the fringes, the distance between these weft threads being between 0 and 1 mm, preferably between 20 and 200 ⁇ m.
  • Two fringe layers separated by a fringe layer are connected to one another by weft threads in the partial weft in such a way that the weft thread connects two adjacent rows of stitches to one another.
  • Fields of application for the pollen protection system include windows in house walls, roof windows and door openings such as balcony and terrace doors and the like.
  • the problem of the impassability of the door can be solved by a special design of the fastening system.
  • Another application is in car windows, which allows a pollen allergy to open the window during the summer months.
  • Another possibility of attachment is the use of an additional mushroom tape, which has a felt-like material instead of the adhesive.
  • the additional mushroom tape with the fleece side is applied to the bonded mushroom tape, then the pollen protection fabric is attached.
  • the advantage of using an additional mushroom band is that it is easier to disassemble and reassemble the pollen protection, for example at the end and when the pollen flight period resumes. Since the pollen protection knitted fabric is individually tailored by the user, the knitted structure must also be protected against damage to the knitted structure, such as the unintentional removal of the weft threads.
  • the fleece mushroom tape By attaching the fleece mushroom tape, a protective effect similar to that of a hem can be achieved on the pollen protection fabric.

  • the comparison limit of this method is 10%, ie differences in the filter effect of two samples of more than 10% are significant. Since particles in the room air are also recorded by both particle counters, but it is not known how many room air particles are filtered, the individual values were not corrected. It can be estimated that if the two measured values are reduced by the number of room air particles, the result for the individual value of the filter effect is better.
