Ion-exchange fibers are the fibers with special properties. These fibers are space-cross-linked three-dimensional structures consisting of oriented macromolecules containing functional groups of acid and alkaline nature.

The main feature of ion-exchange fibers is the ability of their functional groups to dissociate in liquid media and exchange gegenions as well as show chemisorption properties.
