Abstract: Clothing pressure distribution in tight-fit sportswear was simulated by using numerical computational method. Three sets of tight-fit sportswears were simulated on the basis of their mechanical properties. In addition, a 3D human body was also simulated in order to investigate its interaction with sportswear in the wearing process. Result shows that pressure increases significantly around the waist girth until it passes through body pelvis during the wearing process. Meanwhile, pressure begins to increase for other tested body locations. Based on body contour plot, we found that pressure distribution was not uniformly distributed and high-pressure zone was concentrated around the waist girth at the end of the wearing process. The simulated pressure has no significant difference (p > 0.05) with the experimental pressure measurements. Furthermore, subjective pressure comfort rating was linearly correlated with the simulation, suggesting the simulation method can provide reliable prediction in term of pressure comfort. From the tight-fit sportswear manufacturer's point of view, simulation result would help them to satisfy consumers' physiological and psychological needs in term of pressure comfort at a lower cost.

The purpose of this paper is to compare different approaches toward the prediction of human psychological perception of clothing comfort performance from fabric physical properties. A series of running wear trial, which involved eight sets of tight-fit garment and 38 subjects, was conducted in an environmentally controlled chamber. Thirty-three fabric physical property indexes were measured and nine individual sensations and overall comfort were rated by subjects during the running period.

Fabric liquid moisture transport properties in multidimensions, called moisture management properties, significantly influence human perceptions of moisture sensations. A new method and instrument called the moisture management tester (MMT) is developed to evaluate textile moisture management properties. This new method can be used to quantitatively measure liquid moisture transfer in one step in a fabric in multidirections, where liquid moisture spreads on both surfaces of the fabric and transfers from one surface to the opposite. Ten indexes are introduced to characterize the liquid moisture management properties of fabrics. Eight sets of sportswear are tested with the MMT and the results show that liquid moisture management properties are significantly different for these fabrics. The objective measurements are compared with subjective perceptions of moisture sensations during exercise. A fabric's one-way-transport capacity and its overall moisture management capacity are significantly correlated with perceptions of clammy and damp sensations with increased exercise time indicating that subjective perceptions of moisture sensations in sweating such as clammy and damp can be predicted by the measurements of the MMT.
