“…In other words, convective heat transfer rate during forced convection is significantly higher than natural convection. This result is similar to the outcomes obtained by Bhattacharjee andKothari (2008), andSargolzaei et al (2021). Based on the Newton's law of cooling that is represented in equation ( 3), convective heat transfer rate is influenced by the surface area of the cylinder, primary temperature of microclimate and wind flow temperature which in the current study, all of these parameters were kept constant through the test procedure.…”

“…Joshi et al (2021) provided a model for the forced convective heat transfer that is influenced by the body movement accompanied, ambient air speed and garment fit, considering heat transfer mechanisms such as conduction, radiation and convection (Joshi et al, 2021). Sargolzaei et al (2021), investigated the effects of wind speed and air gap thickness (concerning the garment size), on the microclimate ventilation of garment. In this research, it was shown that at different wind speeds, the variation of the air gap temperature depends on the air gap thickness.…”

“…In this research, it was shown that at different wind speeds, the variation of the air gap temperature depends on the air gap thickness. Moreover, wind speed is also an important factor, which influences the microclimate ventilation due to the forced convection heat transfer (Sargolzaei et al. , 2021).…”

PurposeThe aim of the present study is to investigate the effect of fabric weave structure on air permeability and its relation with the garment ventilation.Design/methodology/approachFor this purpose, five groups of cotton/polyester shirting fabrics with plain, T2/1, T2/2, T3/1 and T3/3 weave structures were studied. In order to evaluate ventilation, the garment samples were prepared in different sizes, so that the thickness of the air gap formed between the garment and the body simulator varies by zero, 1.5, 1.2 and 2.9 cm. The effect of wind and its speed (1, 2 and 3 m/s) on clothing ventilation has also been evaluated.FindingsThe results indicated that the rise of wind speed and air gap thickness, due to the increased convective heat transfer, would diminish the air gap temperature of clothing and improves its ventilation. In addition, the fabric weave pattern influences the air ability to pass through the fabric, thus affecting the ventilation capability of the garment.Originality/valueGarments made of fabrics with higher structural firmness, such as the plain, not only have lower air permeability, but also has weaker ventilation capability.

In prevailing simulations of garment thickness, typically characterized by uniform pressure filling, variations in thickness across different sections of the garment are commonly not addressed, and the aspect of elasticity is regularly omitted. In this paper, the garment thickness is simulated by constructing a multi-layer spring-mass model, where the garment thickness is determined by the fabric properties, for example, cotton, pink ribbon brown, royal target, etc. Specifically, the spring coefficients of the multi-layer spring-mass model represent the garment thickness, which is obtained by computing the physicochemical properties of the fabric through a heat transfer equation. Meanwhile, the fabric properties also determine the upper and lower limits of the garment thickness (i.e. the limitation of spring deformation), which can be simulated as a single-layer garment or garment with thickness. With computer simulation verification, fabric properties and the multi-layer spring-mass model can simulate single-layer, multi-layer, and garments with different thicknesses. The simulation effects are similar to those of real-world garments.
