Selected barrier properties of some disposable protective coveralls in wet state

Popis výsledku v původním jazyce

Certain types of disposable protective clothing should protect its user against liquids including water; therefore, the knowledge of their thermophysiological and barrier properties in wet state is important, as moisture mostly deteriorates comfort-related barrier properties of clothing, namely its water vapour permeability and thermal insulation. However, papers on comfort-related barrier properties are almost missing, as testing of these properties in wet state is very uneasy, due to long times of testing of these properties in standard commercial instruments. If the testing time exceeds 15 to 30 minutes, the sample gets dry and the testing is practically impossible. In the study, a special testing instrument is presented, which enables to measure water vapour permeability and thermal resistance of wetted fabrics within a few minutes, thus making possible the determination of these parameters with satisfactory precision. By means of this unique instrument and other instruments, water vapour permeability, air permeability and hydrostatic resistance of 6 wetted protective coveralls were determined. The main finding of the study is that due to the absorbed moisture, the effective relative water vapour permeability of the studied clothing gets substantively reduced, as well as their air permeability.
