Thanks to DWR treatment, the tissue does not get wet; that is, it does not absorb water and, as a result, does not become heavier and dries faster. Together with water, various contaminants do not penetrate the tissue structure, which acts as an abrasive and reduces the durability of the product. In the case of membrane tissue or capillary materials, DWR does not allow absorbed water to interfere with their "breathing" properties.
