Definitions

  • the invention relates to the use of textured thread material in textile fabrics, which are used as a pollen filter to protect against the ingress of dust-like allergens transported by the atmospheric air, such as pollen dust and fungal spores, in living and working spaces by means of the full-surface attachment in front of windows and doors.

  • 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 given, for example, in DE 197 22 326 A1.

  • 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.

Since the pollen protection knitted fabric is individually cut by the user, the knitted fabric structure must also be protected against damage to the knitted fabric structure, such as unintentional pulling out of the weft threads. By attaching the fleece mushroom tape, a protective effect similar to that of a hem can be achieved on the pollen protection fabric.
