FIELD: medicine. ^ SUBSTANCE: invention concerns medicine, and in particular, to the air-penetrable back insertion containing the first water-vapour transmitting layer and the second water-vapour transmitting layer, for an adsorbing product where the back insertion is water-vapour transmitting in a Z direction. The back lining contains a condensation zone between two layers. The first layer is fitted for passing of the first quantity m1 of water steam at the mass expense through the first layer in Z direction where the second layer is fitted for passing of the second quantity m2 of water steam at the mass expense through the second layer in a Z direction. The condensation zone is fitted for time condensation and storage of quantity t-mc of water steam so there will be no formation of water steam condensate on an external surface of the back insertion. ^ EFFECT: absence of formation of water steam condensate on an external surface of the back insertion. ^ 18 cl, 6 dwg |
