A ventilation insert for textiles, with at least one layer, covered at least partially by an absorption material and having ventilation openings, the openings being at least partially closeable via a liquid by swelling of the absorption material, obtainable by: a) treating a layer having ventilation openings with a mixture, containing a wetting agent, initiator, polymerizable monomer or oligomers, and a cross-linking agent, as a preliminary stage for the absorption material; and b) polymerizing the monomer or oligomer to form the absorption material while forming a bonded connection between the absorption material and the layer. The ventilation insert has a relatively low thickness, a low weight per unit area, and high flexibility permanently and independently of moisture after economical production, via one layer, self-sealingly closing ventilation openings, and containing the absorption material. The absorption material is connected to the layer by bonding, at least in some regions.

Ventilation insert

An electrically conductive sheet material having a base body with fibers, at least part of the fibers having carbon fibers, optionally having channels extending through the base body, capable of providing an electrically conductive and flexible sheet material which has a low electrical resistance and which can be produced on a large scale in the most simple, cost-effective and reproducible manner possible.
