This chapter provides a comprehensive review of protective clothing in both hot and cold environments, employing a systematic approach based on the five essential research steps. These steps include: Step 1—Survey on protective clothing, Step 2—Textile performance tests, Step 3—Thermal manikin tests, Step 4—Human wear trials in hot and cold environments, and Step 5—Mobility tests. While it is imperative for protective clothing to offer adequate safety for workers, it is crucial to acknowledge that enhanced protection may lead to heightened discomfort, thereby imposing an additional physical burden on workers. The thermal performance of textiles is evaluated through key thermal properties such as thermal resistance, thermal absorptivity, thermal conductivity, breathability, and air/water vapor permeability. In order to assess the thermophysiological properties of clothing, including the air layers within clothing, thermal manikins are employed. This chapter delves into various issues concerning test methodologies associated with the use of thermal manikins, such as partial and overall clothing insulation, calculation methods, the controlled induction of sweating to measure water vapor resistance, and the impact of air velocity. The subsequent section focuses on the fourth step, where human wear trials in hot and cold environments are introduced. In hot environments, workers who wear protective clothing often face heat-related disorders. The chapter presents studies on estimating the physiological strain of workers in hot environments, along with studies on body cooling garments. Furthermore, the discussion extends to cold protective clothing, emphasizing the concept of thermal insulation through the thermal manikins and active heating. Finally, mobility tests or practical performance test, which simulate the movements and postures associated with specific work tasks, are introduced. The enhancement and effective development of protective clothing in thermal environments are contingent upon a comprehensive adherence to the outlined five-step approach.

摘要

This chapter provides a comprehensive review of protective clothing in both hot and cold environments, employing a systematic approach based on the five essential research steps. These steps include: Step 1—Survey on protective clothing, Step 2—Textile performance tests, Step 3—Thermal manikin tests, Step 4—Human wear trials in hot and cold environments, and Step 5—Mobility tests. While it is imperative for protective clothing to offer adequate safety for workers, it is crucial to acknowledge that enhanced protection may lead to heightened discomfort, thereby imposing an additional physical burden on workers. The thermal performance of textiles is evaluated through key thermal properties such as thermal resistance, thermal absorptivity, thermal conductivity, breathability, and air/water vapor permeability. In order to assess the thermophysiological properties of clothing, including the air layers within clothing, thermal manikins are employed. This chapter delves into various issues concerning test methodologies associated with the use of thermal manikins, such as partial and overall clothing insulation, calculation methods, the controlled induction of sweating to measure water vapor resistance, and the impact of air velocity. The subsequent section focuses on the fourth step, where human wear trials in hot and cold environments are introduced. In hot environments, workers who wear protective clothing often face heat-related disorders. The chapter presents studies on estimating the physiological strain of workers in hot environments, along with studies on body cooling garments. Furthermore, the discussion extends to cold protective clothing, emphasizing the concept of thermal insulation through the thermal manikins and active heating.
