Walking speed is equivalent to 1 m/s, while running speed is 2 m/s. Knitting fabrics made from natural and synthetic fibres were used to examine how hydrophilic and hydrophobic properties influence evaporation. Visualising the evaporative cooling heat flow kinetics allowed us to identify different evaporation stages. We defined new parameters: Qmax , Qmin , Qeq , Flow drop (Qmax – Qmin ), and equilibrium time. Qmax represents the thermal absorptivity of water vapour at the very first moment of contact between the fabric and the skin. Qmin signifies the decrease in the cooling flow. Teq denotes the equilibrium time. These parameters describe the dynamics of water vapour transfer. The results showed that incorporating synthetic fibres into a fabric enhances its breathability, lowers the temperature, accelerates drying, and provides a refreshing sensation when first touched by the skin. It was found that Coolmax is twice as cool as wool.}, number = {06}, urldate = {2026-01-01}, journal = {Industria Textila}, author = {Benltoufa, Sofien and Algamdy, Hind}, month = dec, year = {2025}, pages = {861}, }
