“…The decreasing of SF1 and SF2 indicated that the moisture (sweat) evaporates and takes away the thermal energy, which means the moisture played a significantly positive role for MMP + fabrics during the exposure. 54,55 When the sweat rate increased from SR10 to SR19, a more significant relative decreased rate of unit sweat rate (∆EAE SR19-10 * = (EAE SR19 -EAE SR10 )/EAE SR10 /(19-10)) occurred for SF1 (−0.78%) than SF2 (−0.11%). This phenomenon could be explained by the differences in the in-plane and trans-planar wicking of liquid moisture, 56 which is related to the moisture transfer performance among various fabric types.…”

Human perspiration significantly affects heat and mass transfer in clothing systems and absorbs thermal energy on the skin, especially in radiant exposure and high-intensity work. However, few testing devices simulate human sweating for assessing heat transfer under thermal radiation exposure. Thus, a test device that could realistically simulate specific sweat rates was developed to evaluate the influence of continuous sweating on thermal protective performance (TPP). The TPP of single-layer fabrics at dry (No-sweating) and three constant sweating rates was studied based on the calibrated tester. It was indicated that the new testing apparatus effectively evaluated fabrics’ dry and wet thermal protective properties. Furthermore, compared to continuous sweating, the traditional pre-wet method may overestimate the TPP of the single-layer fabric depending on sweating rates. The continuous sweat rates played a dual role in the second-degree burn time and absorbed thermal energy, which is related to the moisture management performance of fabrics. The research provides an effective method to characterize the TPP of materials under continuous sweating/wetting, which will help optimize clothing performance and update relative standards.

“…More recently, Eryuruk et al [18] investigated the thermal comfort and moisture management of a firefighter garment with a new fire-resistant underwear. They analyzed the performance characteristics of single-layer fabrics (underwear, outer shell, moisture barrier, and thermal barrier) and their three-and four-layer combinations to better understand comfort and protective performance.…”

The comfort properties of fabrics are closely related to their structural parameters. Various material and construction changes affect thermal insulation, permeability properties, wetting and water vapour permeability, which are the most important properties related to the comfort of textiles. Thermal comfort evaluation plays a crucial role in the development of textiles and is mainly carried out in the three aspects of breathability, heat transfer and moisture transfer. The aim of the research is to investigate the comfort and flame retardant properties of knitted fabrics made of four different materials: three conventional (cotton, Tencel and Micromodal) and one flame retardant material (blend of Tencel, polyacrylate, Modacryl-Tayrilan) that can be used for firefighter underwear. All materials were knitted in three different constructions of double jersey. It was found that the blend of Tencel, polyacrylate and Modacryl-Tayrilan is a truly flame retardant material suitable for firefighter underwear and has good comfort properties.

“…The results showed that although the disguised materials had good thermal protection, they improved the thermal hazard. Chen 15 –17 analyzed the heat transfer of protective clothing through FPGA simulation software and temperature sensor, and verified the transfer model by comparing with the experimental data. In their research, the thermal comfort performance of protective clothing was optimized, which could protect the skin from the thermal damage caused by low-intensity thermal radiation.…”

In low temperature environment, electric heating clothing can provide extra heat for human body through built-in heat source, so it has better thermal insulation effect. The thermal analysis is the initial step for electric heating clothing design. The current thermal analysis of electric heating textiles focuses on the fabric itself instead of the effect of skin tissue metabolism and heat production. In order to improve the accuracy of skin surface temperature prediction, the biological heat transfer need be modeled to analyze the internal temperature distribution of the heating suit system. In this paper, a three-dimensional (3D) thermal analysis model of electric heating clothing combined with human skin tissue is established. Firstly, the coupling analysis of Fourier heat conduction and Pennes biological heat transfer equation is carried out. Then the reliability of the 3D thermal analysis model is verified by finite element analysis (FEA). The results show that the fitting error between the three-dimensional model analysis data and FEA simulation data is 5°C, which proves that the model can accurately predict the system temperature. Finally, we make further research about the effects of ambient temperature, clothing layer thickness, and input power on the maximum skin surface temperature. This study provides theoretical foundation for the design of wearable thermal management fabric.
