A review of major innovations in wearable clothing for thermal and moisture management from material to fabric structure.
Human body exchanges heat through the environment by various means such as radiations, evaporation, conduction and convection. Thermophysiological comfort is associated to the effective heat transfer between the body and the atmosphere maintaining the body temperature in a tolerable thermal range (36.5 – 37.5 oC). So that, to ensure the thermophysiological comfort, the body heat must be preserved or emitted depending on the external atmospheric conditions. If the body heat is not properly managed can cause hyperthermia, heatstroke, and originating thermal discomfort. Conventionally, the installation of heating, ventilation, and air conditioning (HVAC) systems used to provide the thermophysiological comfort. But it requires huge capital, consumed high amount of energy leading to increase in global warming and only limited to indoor applications.
In the recent decades, scientists across the world are working to provide the thermal comfort though the wearable innovative textiles. This review article proposes various strategies of moisture and thermal management at material, filament/fiber, yarn, and fabric scales., yarn and fabric scale is comprehensively described and also summarizes the passive and active textile models for the thermal comfort. Integrating the electrical devices in the garments can rapidly control the skin temperature, dynamic and useful for wide range of environmental conditions. But their use can be limited in some situations due to their bulky and heavier design and batteries must be frequently recharged for their continuous functioning. On the other hand, adaptive textiles enable the wearer to maintain the thermal comfort in various temperatures and humidity without requiring the exterior power source. Using these wearable textiles are convenient to provide the thermal comfort at the individual level rather than controlling whole building temperature mitigating the high energy consumptions and global warming effect.
Personal thermal regulation textile, moisture and thermal management textile, thermo-physiological comfort.
The photonitex project aims to develop a new type of intelligent textile that will improve thermal comfort by dynamically regulating the space between the skin and the textile. These innovative garments will be able to return infrared radiation to the body depending on the conditions of use: temperature (body or external) and humidity (perspiration). This feature is not only for athletes.
It also covers personal protection, insulation, military engineering and interior textiles. To achieve this objective, phototex proposes to take inspiration from photonic structures, which are nanostructures that interact with light according to their wavelength (i.e. their color). They allow, for example, some butterflies to display their shimmering colours. If their manufacture uses nanotechnologies, we will, in phototex, generate similar structures adapted to infrared “light” using methods compatible with the textile industry.
