“…Advanced simulation and modeling based fabric testing techniques have the potential to overcome the complexity and long-time consumption associated with the conventional clothing testing, consequently the testing methods will be more efficient and results for the thermal comfort will also be more authentic and reliable. Especially modeling and simulation of heat transfer and the thermal response of the human body have gained the considerable attention of researchers from academia and industry which have resulted in the development and application of different human thermal response models [23][24][25][26][27][28] for versatile industrial applications [29][30][31][32][33][34][35].…”

Human thermal comfort within various environmental conditions is of paramount importance in a wide range of industries, including clothing design, indoor climate control, and occupational safety. Researchers are always in search the sophisticated tools and techniques that simulate the thermal regulation of human body under different environmental conditions. The present research aims to present a precise methodology for the simulation of clothed thermal manikin in controlled environmental conditions. A comprehensive method is recommended that consists of the use of 3D body scanning technology, different 2D and 3D CAD as well as thermal simulation software. The results of the simulations are very satisfactory, which are later validated with the wear trials with the help of the same clothed thermal manikin and under the same environmental conditions. The comparative analysis shows some deviations that are discussed thoroughly and the need for further research is highlighted in the papers as well. Furthermore, the present research gives us a digital platform to understand the clothing's thermal comfort and the parameters that affect it with the consideration of the draping behavior of the clothing, microclimate, thermal properties, and surrounding environmental conditions.

Firefighter protective clothing research has undergone rapid development and garnered extensive attention over the past three decades. However, its trajectory lacks quantitative evaluation due to the complex relationship among humans, clothing, and the environment. Here, we aimed to (1) develop an objective and reproducible evaluation index system for the quantitative assessment of firefighter protective clothing research, (2) delineate the developmental stages and their analytical characteristics over the past three decades through bibliometric analysis, and (3) scrutinize the current status, research hotspots, gaps, and future concerns. Our review of 314 publications from the Web of Science Core database (1994–2023) led to the creation of an evaluation index system that integrates the catastrophe progression method with bibliometric analysis, incorporating 10 indicators across 4 dimensions: productivity, influence, development, and innovation. The bibliometric analysis was conducted using the Bibliometrix R package. The results reveal a rapid increase in firefighter protective clothing studies from 1994 to 2023, comprising two stages: the start-up phase (1994–2009) and the rapid development phase (2010–2023). Thematic evolution over three decades indicates a shift from single specific to composite domains, with emerging themes such as achieving a balance in the interaction between the human body, clothing, and environment signaling future research directions. In addition, we visualized the most relevant countries, institutions, journals, authors, articles, and potential challenges during the last 30 years. This review provides an overview of current evidence and minimizes subjectivity bias compared to traditional manual reviews, thus presenting specific future research questions advancing firefighter protective clothing research.

The influence of environmental conditions on the thermo-physiological comfort of men's socks was investigated using an objective assessment of comfort under dynamic conditions. Men's socks made in a 3:1 rib construction from three types of basic yarns (77%) were used: bamboo, cotton, and a cotton/polyester blend. The remaining composition of the socks is identical: filament polyamide yarn (22%) and wrapped rubber thread (1%) for the welt. The influence of climate factors artificially created in the climate chamber was analyzed by measuring three physiological parameters: skin temperature, relative humidity of the skin, and microclimate in the space between the sock and the shoe on both feet. The research results show that the raw material composition of the base yarn used in the manufacture of men's socks has a significant impact on thermo-physiological comfort when wearing socks. Under artificially created conditions in the climate chamber, an ambient temperature of 20 °C and relative humidity of 50% (autumn and spring conditions), socks with basic yarn made of a cotton/polyester blend are preferred, then with a base yarn made of cotton, and finally socks with a base yarn made of bamboo. The data from the study provide valuable information for the clothing industry in designing and defining the choice of base yarn to produce socks, depending on the conditions of use.
