Abstract Spacer structures are knitted fabric constructions comprising two separate fabricwebs which are joined together by spacer threads The spacer threads are generally madeof PET or PA monofilament yarns These fabrics because of their special properties havemany applications such as protective and sports clothing and shoes seat covers bandages In order to investigate the dynamic moisture transfer of spacer fabrics anexperimental apparatus has been developed which enable the simulation sweating ofhuman body It consists of a controlled environmental chamber guarded hot plate andhumidity sensors and data acquisition system With comparison of moisture transfer between spacer fabrics and leather it isobvious that moisture transfer of spacer fabric is very higher than moisture transfer ofleather Then with comparison of different samples the influence of some parameterssuch as heat setting the kind of spacer threads air permeability thickness and porosityon moisture transport properties are investigated Spacer fabrics well able to transport themoisture increase in the microclimate close to the skin during intermittent perspiration ofthe human subject and they also guarantee excellent wear comfort Heat setting underdrawing of spacer fabrics increases the porosity and air permeability and decreasesthickness and weight per unit area With Increasing of porosity and air permeability moisture transport is increased The Results shows that water vapor produced by sweating can be easily and quicklytransferred from next to the skin to the outer surface to keep the skin dry A mathematicalsimulation of moisture diffusion into spacer fabrics is developed and the model is solvednumerically by the finite difference method The results of water vapor concentration in air andwater vapor concentration in fibers are illustrated by a series of 3D diagrams in terms of time anddifferent thickness of fabric
