TL;DR
This study examines how fabrics dry when in contact with the human body, showing that drying rates are significantly affected by skin contact and fabric stretch.
Contribution
The study introduces a method to quantify fabric drying performance under realistic skin-contact conditions, which is novel compared to standard testing methods.
Findings
Contact with a heated surface like skin significantly increases fabric drying rates compared to two-sided drying.
Fabric stretching while in contact with a heated surface further enhances drying rates.
Observed drying rates varied widely depending on the drying condition tested.
Abstract
When developing fabrics for applications in which evaporative cooling and drying play an important role, e.g., sports or occupational applications, the drying performance of fabrics is commonly determined using fast and easy-to-perform benchmark methods. The measurement conditions in these methods, however, differ significantly from the drying conditions on the human body surface, where drying is obstructed on one side of the fabric through contact with the skin and at the same time enhanced due to contact with the heated surface (skin). The aims of this study were to understand and quantify the fabric drying process at the skin interface considering these real-use effects based on tests applying two-sided drying, one-sided drying, one-sided drying on a heated surface, and one-sided drying on a heated surface in the stretched state, and to relate these to existing standard methods.
