Thermo-physiological properties are very much connected to water vapour and air permeability. There are multiple standards with different working principles to determine the exact performance of any textile material. However, most of these tests are time-consuming and work on the steady state principle, whereas few devices work on heat flux, where results can be obtained much more quickly. The research article covers the testing of 8 unique shirt samples on these devices compared that on a novel device created by the author to see how much the results differ from each other. Lastly, a theoretical approach was used to determine any correlation between air permeability and water vapour permeability. The research work helps in understanding the working of different devices used for water vapour permeability and allows a reduction in time by using a predictive approach with just the results from the air permeability machine.
