GENERAL PURPOSE MULTI-LAYER MATERIAL, FORMING FLEXIBLE DISTRIBUTION CHANNELS SYSTEM FOR SELECTION, FILTRATION, DISTRIBUTION AND DRAINAGE OF FLUID MEDIA Russian patent published in 2017 - IPC B32B33/00 B01J20/00 

FIELD: satisfaction of human life necessities.

SUBSTANCE: material versions contain three consequently bonded layers. The first layer is made of the polymer film. The middle layer is made of the polymer film, which is formed as the plurality of convex elements, filling with gas. The third layer in the first embodiment is made of the non-woven material, in the second layer it is made of the cellulose-based filter cloth, in the third one it is made of the perforated polymer film. As the result of the third layer bonding to the entire plurality tops of the middle layer gas-filled elements, the system of flexible distribution channels is formed as the plurality of continuous cavities, separated between each other by the plurality of convex gas-filled elements. The presence of the through hole in the material provides the selection of fluid media and its draining from the material, creates the conditions for ventilation of the flexible distribution channels system, maintains the required level of moisture inside the material. The possibility of the material layers bonding along its edges allows to avoid choking of the internal material structure. The natural and forced fluid media drainage from the material, as well as the gas exchange is provided through the layers bonding.

EFFECT: extension of the technical facilites range.
