 Full text | Abstract: Textile laminates with breathable membranes are used extensively in waterproof clothing items such as jackets, footwear and gloves. The polymer membranes act as a barrier to liquid water and soil entry from the environment, but they are sufficiently permeable to water vapour to allow significant amounts of sweat to evaporate through the clothing system and greatly affect the comfort of the wearer. In this paper the influence of the multifold water vapour resorption/desorption process on the hygienic properties of textile footwear lining laminates is presented. The water vapour resorption/desorption process was carried out by the repeating of three-cycle water vapour absorption and drying. It was shown that the water vapour absorption behaviour of textile laminates can be classified as Fickian. The equilibrium of water uptake increases with an increase in the resorption/desorption process. The resorption/desorption process influences not only the absorption parameters of laminates, but also changes the character of sorption kinetics – it influences the water uptake and drying times of laminate. It was determined that the moisture transport properties textile lining laminates are history-dependent. |
