Abstract
The adsorption of permeating chemical compounds on the textile materials active surface is one of many principles of personal protection against dangerous chemical compounds including chemical warfare agents. The adsorption principle is generally known. However, its effective application especially in connection with the enhancing protection efficacy follows certain significant rules. A development of new textile materials based on the application of adsorbents in the combination with nanofibrous materials is the main topic of contemporary research in this area. This contribution sums up the theoretical basis of adsorption-based protective efficacy and also brings new experimental results of sorption and permeation of live CWA agents and their simulants through different samples of layered composite materials. Results are related to the basic structural parameters of nanotextiles and applied adsorbents.
