Abstract:

A series of experiments and analyses were performed to study the dynamic heat and moisture transferring procedure as well as evaluate the heat-moisture comfort property of fabric in wearing conditions that produce continued sweat. By measuring five static indexes of ten different fabrics, which involved static heat-moisture transmission through fabric, as well as two dynamic comprehensive indexes obtained from the dynamic curves using a self-made microclimate measuring apparatus, the relation between the static indexes and dynamic comprehensive indexes was established.In addition, an evaluation and prediction system for the dynamic heat-moisture comfort property of the textile was formulated by means of the grey system theory. For two different environmental conditions: the most comfortable ones, and an extremely uncomfortable condition for humans, four different prediction models were built, and high predictive precision was obtained.

Tags: dynamic heat-moisture comfort, temperature and relative humidity, microclimate measuring apparatus, grey system theory.
