Abstract
Diplomová práce je věnována metodikám měření prodyšnosti a paropropustnosti, které nejsou obecně rozšířené. Je vysvětlen rozdíl mezi prodyšností a paropropustností. Je objasněn princip měření prodyšnosti a proveden srovnávací test na třech různých přístrojích. Je vysvětlena problematika tzv. neměřitelných hodnot prodyšnosti. Je zavedena veličina hydraulického odporu textilií. V druhé části práce je popsána a testována nová metoda výpočtu výparného odporu textilií a stanoven vztah mezi hydraulickým a výparným odporem textilií.
Diploma work attention is paid to the measurement methodics of the air permeability and the water vapour permeability, which are not generally used. Difference is defined between the air permeability and the water vapour permeability. The princip of the air permeability measurement is consecrated and the comparative test made on three different instruments. The problem of immeasurable values of the air permeability is consecrated. The new value of the air permeability resistance is established. In the second part of the diploma work there is described and tested the new method of calculation water vapour resistance and set the relation between the hydraulic resistance and the water vapour resistance of fabrics.
