  • the quantity of polymeric material in the auxiliary layer is so small, that in principle it does not play any role in what formations it is to be found. Therefore for creation and deposition ⁇ of the auxiliary layer of polymeric material even other methods of electrostatic spinning than those utilising some of the above mentioned spinning electrodes, or generally even other principles than the electrostatic spinning, may be used.

  • the layer of functional nanofibres in principle on any substrate, not only on the textile described in example, of embodiment.
  • the auxiliary layer of nanofibres and their surface dissolution possibly in combination with surface dissolution of nanofibres of the functional layer, secures a sufficient adhesion of the functional layer in principle to any surface and material.
  • the functional layer of nanofibres may be therefore deposited not only on planar units such as filtration paper or filtration textile, but also, on .surfaces in principle of any products from any material, both finished or designed for further processing.
  • the described procedure eliminates disadvantages of the background art in such a manner that it enables any combination of polymeric material of auxiliary layer with material of the functional layer of nanofibres, simultaneously secures a high adhesion .of .the auxiliary layer to the substrate immediately after depositing the auxiliary layer or during it.
