In the case of excessive body temperature, the human body activates the sweat
mechanism, and heat evaporation leads to heat loss. Clothing, by its characteristics,
largely determines the exchange of heat between the body and the environment.
Today’s clothing is often subjected to the printing process, in order to increase its
aesthetic value. The printing process changes textile materials, and thus changes
clothes made from these materials. This paper presents research on the influence of
printing cyan ink on the thermo-physiological features of textile materials. The
effects of ink on thermo-physiological characteristics of substrate materials were
determined by measuring water vapour resistance. The obtained results show that
cyan ink in combination with material characteristics have an impact on the water
vapour resistance of textiles.
