The Application Wearable Thermal Textile Technology in Thermal-Protection Applications
Journal Title: Latest Trends in Textile and Fashion Designing - Year 2018, Vol 1, Issue 2
Abstract
With the capability of the human to survive in various extreme environments is growing stronger and stronger, the desire to act and move freely in chill condition is growing as well. Although the surviving ability in the extremely cold condition has been confirmed, the free motion and activity in the chill environment and the thermal comfort is still a problem. In some circumstance, people need to work or do exercises in this severely cold condition so that they may sacrifice their thermal protection for a period to exchange for free motions and activities, because this thermal protection is too heavy, thick and blocky and it is also a kind of striction. In these circumstances, human is easy to be cold injured, such as frostnip, frostbite, trench foot, and even whole-body hypothermia etc. These cold injuries can occur on any body part, but tends to occur more on exposed areas such as the face and on the extremities, which have a high surface area to mass ratio and are also more often exposed to conductive heat loss. Some cold injuries are permanent and incurable. Meanwhile, although human can survive through the low temperature condition, thermal comfort is still a problem that the traditional passive thermal-insulate clothing protection, which is thick and in blocky multi-layer structure, to prevent the heat dissipation to the environment as less as possible. In this circumstance, the heat energy source is only the human body itself. While in these extreme condition, the tradition passive thermal protection is insufficient. Further, this bulky and massive multilayer structure constrains the free movement of human beings, especially when human doing exercises and conducting works in chill winter outside trials. Typically, the applicators involve relatively thick bulky compresses which do not conform closely to the contour of the body. Failure of the compress to conform closely and to retain close contact once positioned, results in irregular heating of the ski area. This problem often results in irregular or non-uniform healing of the skin, swelling, and the like. Further, due to its passive working-machinimas, this protection is far insufficient to maintain the thermal comfort of wearers in extreme condition, especially for the children and the elderly groups. Thus, an innovative flexural wearable active thermal technology is under research [1-3].
