“…Fatores como oscilação de temperatura, contato com produtos químicos e exposição a agentes biológicos ou radioativos podem impactar diretamente a saúde dos indivíduos (GUAN et al, 2018). Profissionais como bombeiros, trabalhadores da indústria petroquímica e da área da saúde, entre outros, necessitam de vestuário adequado para garantir sua segurança e bem-estar (GUAN et al, 2018;ŁAPKA;FURMAŃSKI, 2020). Portanto, é evidente que questões termofisiológicas podem ser exacerbadas pela falta de uso de vestimenta apropriada para situações específicas (GUAN et al, 2018), o que pode gerar ou agravar problemas de saúde.…”

A moda é uma área de estudo interdisciplinar que aborda questões sociais, históricas, ambientais, de gênero, de saúde, entre outras, tendo forte relação com os modos de se vestir de um indivíduo ou sociedade. Este estudo tem o objetivo de investigar como o uso do vestuário atua sobre a saúde dos sujeitos, para isso realizou uma revisão de escopo, com abordagem qualitativa e exploratória na literatura de 2017 a 2023, por meio das bases PubMed e Periódicos Capes. A análise de conteúdo foi empregada para apresentar resultados significativos acerca do assunto. Identificou-se seis questões cruciais dessa relação: poluição ambiental, contaminação dérmica, questões corporais, antropométricas e termofisiológicas, pressão exercida pelo produto, segurança e normas, e questões de envelhecimento. Observou-se que o vestuário influencia tanto aspectos emocionais quanto a qualidade de vida e bem-estar, abordando aspectos práticos de adorno, proteção e pudor. No entanto, é evidente a necessidade de pesquisas mais profundas e medidas práticas para atender às necessidades dos usuários e promover a saúde. Este estudo visa contribuir para pesquisas em moda e áreas relacionadas à saúde, chamando atenção para o tema e abrindo possibilidades para futuras pesquisas.

“…To study heat transfer in the skin–microenvironment–fabric system at different movement speeds, the current model divides the human body movement speed into three levels: low (300 s), medium (100 s) and high (60 s), based on the time it takes the firefighter to reach the location closest to the heat source [ 15 ]. At different movement speeds, the corresponding fabric movement frequencies (0.25, 0.5 and 1rps) are assumed [ 26 ]. As the human body movement speed increases during radiative heat exposure, the firefighter returns from the fireground and remains at the initial point.…”

“…Udayraj then investigated heat transfer in horizontal and vertical microenvironments during human body movement [ 25 ]. Łapka et al calculated mass transfer in the skin–microenvironment–fabric system during human body movement by accounting for water vapor diffusion transport, adsorption and desorption [ 26 ]. The preceding studies either focused on dynamic variation in heat exposure distance or characterized human body movement through fabric periodic movement, but the overall effects remain unknown.…”

This study proposed an extended multi–layer heat transfer model to simulate skin burns of firefighters during firefighting. The proposed model takes into account the effect of fabric movement frequencies, fabric movement amplitudes and human body movement speeds on the heat transfer between the skin and the heat source under low–level radiative exposure. The simulation performance was validated against the simulations in the published literature in terms of the heat transfer in the multi–layer fabric system, skin temperature and skin burns. The results indicated that the fabric periodic movement caused by human body movement decreased the time to skin burns and the skin temperature increased with increasing fabric movement amplitude. During firefighting, the time to 2nd degree burn was 33.3–35.2% shorter at medium human body movement speed than at low and high movement speeds. Furthermore, at low movement speeds, the time to 2nd degree burn was negatively associated with fabric movement amplitude, whereas it was delayed by 12.9–29.8% at the fabric movement amplitude of 2.5 mm at medium and high human body movement speeds. This research provides foundational knowledge for the development of a new generation of firefighters’ protective clothing (FPC) and the assessment of skin burns in firefighters.

“…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.
