Method of increasing hydrophobic properties of flat layer of polymeric nanofibers, a layer of polymeric nanofibers with increased hydrophobic properties and layered textile composite, which comprises such a layer

摘要

The present invention relates to a method of increasing the hydrophobic properties of the surface layer of polymer nanofibres, wherein the surface of this layer or throughout its structure deposited hydrophobic agent, during its storage and / or after the layer of polymeric nanofibers acts at least on one side of the air stream, the effects of which are hydrophobic means of transfer from the surface layer of polymer nanofibres on its side in this inter-fiber space in its internal structure. During this time and / or after the layer of polymeric nanofibers further an elevated temperature which is lower than the melting point of the polymer nanofibers, resulting in it contained hydrophobic agent dries and coagulated, thereby to at least some inter-fiber spaces layer of polymer nanofibres may make impenetrable to liquid water the hydrophobic composition in the solid state, and the polymer nanofibres are fixed against mutual slippage. The invention further relates to a planar layer of polymeric nanofibers whose hydrophobic properties were increased in this manner, a laminated textile composite material which comprises a layer of polymeric nanofibers.
