Enhancing Thermal Management by using Thermo-Reflective Materials

Popis výsledku v původním jazyce

Keynote speaker of lecture: Enhancing Thermal Management by using Thermo-Reflective Materials. Individual heat regulation is necessary for human comfort and function. Warming, cooling, and adaptive thermoregulation—all essential for carrying out daily activities—are included in thermal management. Human comfort is in the temperature range of 20 to 27 oC and the relative humidity range of 35 to 60%. Extreme heat or cold can overwhelm the body‘s coping systems for physiological thermoregulation, causing lethal situations due to body heat and sweat from vigorous activities. The human body produces around 10 µm of electromagnetic radiation, which when combined with clothing, greatly lowers the surrounding temperature, enhancing the effectiveness of insulation under clothing in adverse weather situations. Textiles with far-infrared (FIR) properties return heat radiation to the human body. There are many different subjects covered, ranging from how the body produces heat to how radiation travels through the skin to do so. At the molecular level, FIR has significant rotational and vibrational impacts that may have positive health consequences. Generally, after receiving heat from the body or sunshine, FIR textiles are made to convert that energy into 4-to 14-micrometer-wavelength FIR radiation and return it to the body. The growing need for clothing that is warm, cozy, light, and healthful can be satisfied with FIR textiles. This study‘s primary goal is to outline the process for producing the FIR reflective textile layer, which is a component of multilayer textile constructions with improved thermal protection. Utilizing the lightweight polyester nonwoven structure Milife, which has the advantageous qualities of low fiber diameters, superior shape stability, and comfort, a copper nanolayer was deposited to create the active FIR reflecting surface. Corrugated multilayer systems with polypropylene nonwoven fabric and an FIR reflecting layer as an active layer were prepared. The properties like morphology, air permeability, infrared spectrum characteristics (copper-coated milife), and thermal properties were analyzed and evaluated. The FIR reflective textile layer created, as part of multilayer textile structures, was observed to have enhanced thermal protection.
