“…This air acts as an insulator preventing heat transfer by conduction and radiation. Yoo et al (2000) found that the thickness of the air layer is negatively correlated with the vapour pressure, which affects the wearer's comfort. Likewise, previous research has demonstrated that the R ct and R et measurements improve when the air gap is considered (Gibson, 1993).…”

“…The effect of moisture on the transfer properties (such as heat and water vapour) of clothing systems at lower temperature (21-35°C) has been extensively investigated and the mechanism is well known (Farnworth 1986;Gibson 1993;Parsons 1994;Weder et al 1996;Yoo et al 2000;Fan and Chen 2002). However, this phenomenon is rather complex when fire-fighting is considered as it involves high temperature.…”

Fire-fighters' personal protective clothing is the only source of protection for fire-fighters during fire-fighting. The protective clothing should provide adequate protection as well as should be comfortable to wear. The protection and comfort requirements are always the contradicting fact in several protective clothing including fire-fighters'. Appropriate material selection, clothing design and final evaluation of the results play a critical role in predicting the clothing performance and comfort. Several researches have been done on the performance and comfort improvement of fire-fighter's protective clothing. However, detailed review related to these parameters is not being reported in recent years. In this perspective review, we report the recent trends in the performance and comfort properties of the fire-fighters protective clothing. The clothing design and different materials used to achieve a balance between performance and comfort is illustrated. Various test standards related to the performance and comfort is also being discussed. In addition, the future scopes and challenges while designing tomorrows advanced protective clothing are cited. This would provide a guideline in terms of comfort and performance while developing and designing the fire-fighter protective clothing for different climatic conditions.

“…Comfort is basic and universal need of human being and presents one of the most important aspects of clothing. During clothes wearing, heat and humidity produced by body has been stopped as layers of air before passing in the environment, resulting in characteristic microclimate between skin and clothing, defined as the feeling of comfort (Yoo et al, 2000;Grujić et al, 2010). Thermal effects largely contribute to the comfort of the individual, whereby a complex physiological and psychological factors together with clothes play an important role in defining the complex phenomenon of comfort (Andreen et al, 1953).…”

The human body transforms the chemical energy of the food into the work and the heat through the process of metabolism. The produced heat through the skin is transferred to the environment. In this case, in the state of thermal equilibrium, the amount of heat produced is equal to the amount of heat lost by conduction, convection, radiation, evaporation and breathing. The process of conduction of heat is transferred from the body to the environment, through layers of clothing and air, with the person standing still. Conductivity of heat in clothes depends on the thermal conductivity of the fibers from which the clothes are made, the conductivity of the air trapped in the pores of the clothes and the air on the surface of the clothing, the surface of the clothing layer through which the heat and the thickness of the clothes pass. The amount of heat transferred by conduction is usually negligible because the clothing, by its characteristics, slows down heat transfer in this way. Additionally, ink layers made in printing process significantly affect the properties of textile materials and clothes made from these materials. And today textile materials are increasingly being subjected to the process of printing due to aesthetic requirements of the people. This paper investigates the influence of digital printing parameters on the thermo-physiological features of textile materials. The essential print parameter was a different number of passes. In this research were used textile fabric materials of 100% cotton fibers. With printing process parameters, such as number of passes in the print, it is possible to influence the amount of ink that is applied on and in printed material, and thus the achievement of desired values of thermal parameters of printed materials. The influence of print parameters to thermo-physiological properties of the material is evaluated through a thermal conductivity and heat retention ability. Results of the research demonstrated that, in addition to material composition, the printing process with its parameters have a significant influence on the thermo-physiological characteristics of textile materials. The values of the thermal conductivity of the printed samples show that the increase in the number of application of ink in the printing results in a rise in the value of thermal conductivity coefficient, and decrease in heat retention ability value.
