TXR2 ( TXRR ) Thermal Exchange and Rapid Release is the transition in which excessive generated body heat typically found inside the core torso area, during physical activity or hot conditions, is directed towards the skins surface where it will be converted to a valuable coolant. This changeover is achieved by the merger of materials that are both, hydrophobic and hydrophilic along with the introduction of an energy source, that when introduced to the fundamental design will activate the cooling properties found inside TXR2. Because this layered merger of material is adapting to convection and evaporative cooling, heat exchange occurs. Heat exchange (see also Heat Transfer ) is the transference of thermal energy from a hotter source to a cooler source. When an object, such as the torso is at a higher temperature than a surrounding source, transfer of thermal energy (heat transfer), or heat exchange is evident. Based on the second law of thermodynamics (see also Clausius’ statement ), heat exchange will always occur from a warmer temperature source to a cooler temperature. This concept was first developed and tested for use in the US Armed Forces, competitive sports and NASCAR . TXR2 material composition and usages was created by Michael Webb using several synthetic blends of material that act as a conduit for transferring cooling energy derived from a removable and replaceable cooling energy source. This source offers multiple options of usage and applications for the user. Cooling energy is first activated by submersing in water, which when introduced begins a hyper-evaporation process that allows the material to maintain a cooler temperature than its environment. When implemented, the cooling energy is soon introduce to the surrounding material which activates an overall cooling sensation and begins the transition of excessive generated body heat to a reduced temperature. The TXR2 project is supported by test conducted by NASA engineers and laboratories. The findings provided by NASA, which include the early development of the Primary Life Support System (PLSS), show the possibility of cooling energy transference and thermal transference through synthetic materials. As well as the generated data and feedback provided from testing with the US Armed Forces and NASCAR Pit Crews. Fabrics that only promote the wicking aspect of the material make-up create a false sense, in that by quickly pulling perspiration up and away from the skins surface will leave the user feeling cooler. Perspiration or sweat is the body’s natural way of cooling down, without sweat we would not be able to tolerate the heat our bodies produce, 90% (percent) of generated heat is found in the torso area. We sweat in order to keep the body at its normal temperature, which is 98.6° Fahrenheit (37° Celsius). If we lost this bodily function or something prevented the natural use of perspiration we could suffer from heatstroke in hot weather or hot environments. TXR2 embraces and then supplements two of the body’s natural defense mechanisms, convection and evaporative cooling, while controlling any over saturation of moisture brought on by excessive perspiration.
