Investigation of Water Vapour Resorption / Desorption of Textile Laminates
Keywords:textile laminates, water vapour permeability, water vapour absorption and desorption.
The material ability to pass water vapour or perspiration, greatly affects the comfort of the wearer. Therefore, the
influence of multifold water vapour resorption/desorption process on the hygienic properties of textiles footwear lining
laminates has been investigated. It was shown, that in the first cycle water vapour absorption behaviour can be classified
as Fickian. It was observed that the equilibrium water uptake increases with the increase of resorption/desorption cycles.
It was demonstrated, that desorption behaviour of water depends on the textile lining laminates structure. It may be
described by the linear or exponential laws. It was found, that the resorption/desorption process cycles influence the
water uptake and drying times of laminates and moisture transport properties of the textiles lining laminates are historydependent.
