Diagnostic of the composition of fabrics from their thermal permeability in wet state

The thermal permeability of wool, polyester and wool-polyester plain and twill weave fabrics in wet state has been investigated. It is observed that the level and the time dependency of their thermal permeability depend substantially on their mechanical structure and chemical composition. On the basis of the deeper knowledge of these dependencies and wet permeability/time behaviour, some fabric parameters can be derived for the diagnostic of the composition of fabrics.(undefined)
