Summary
A novel textile system (TMRT) offers advanced cooling and moisture management for enhanced comfort and wearability. This breakthrough addresses limitations in conventional protective gear, improving microclimate regulation during prolonged use.
Area of Science:
- Materials Science
- Textile Engineering
- Biomedical Engineering
Background:
- Maintaining thermal and moisture balance in the body-textile microclimate is crucial for comfort and health.
- Current textiles face challenges in providing simultaneous sustained cooling and dynamic moisture regulation.
Purpose of the Study:
- To develop an advanced textile system capable of synergistic thermal and moisture management.
- To address limitations in conventional protective gear regarding heat and humidity accumulation.
Main Methods:
- Coaxial electrospinning to create a core-shell micro/nanofiber structure.
- Incorporation of a moisture-regulating polymer sheath and a thermal-responsive polymer core.
- Characterization of thermal properties (emissivity, reflectivity, thermal resistance) and moisture management (resistance, evaporation rate, humidity sensing).
Main Results:
- The developed textile (TMRT) achieved high mid-infrared emissivity (99.82%) and low solar reflectivity (7.71%).
- Demonstrated outstanding contact cooling (0.43 W cm⁻²), reducing skin temperature by ≈ 6.6 °C.
- Exhibited low moisture resistance (2.49 m² K W⁻¹), high evaporation rate (0.59 g h⁻¹), and precise humidity sensing (0.5% RH).
Conclusions:
- The TMRT provides a comfortable microenvironment, significantly improving thermal and moisture regulation.
- This technology establishes a new paradigm for advanced textiles with synergistic cooling and moisture management.
- The TMRT effectively mitigates heat and humidity accumulation, enhancing wearability in demanding conditions.

01:26Thermoregulation
2.3K
The human body has a sophisticated thermoregulation system that employs negative feedback mechanisms to maintain an optimal core temperature. When the core temperature drops, peripheral and central thermoreceptors send signals to the hypothalamus, activating the heat-promoting center. This center triggers several responses aimed at increasing the core temperature. First, vasoconstriction reduces the flow of warm blood from internal organs to the skin so that the heat is not lost from the skin,...

01:57Adaptations that Reduce Water Loss
27.9K
Though evaporation from plant leaves drives transpiration, it also results in loss of water. Because water is critical for photosynthetic reactions and other cellular processes, evolutionary pressures on plants in different environments have driven the acquisition of adaptations that reduce water loss.

01:19Mechanism of heat transfer
1.9K
Understanding heat transfer mechanisms is essential for understanding how our bodies maintain balance in different environmental conditions. When the environment is thermoneutral, the body is in a state of balance, neither using nor releasing energy to maintain its core temperature. However, when the environment is not thermoneutral, the body employs four heat transfer mechanisms to maintain homeostasis: conduction, convection, evaporation, and radiation. These mechanisms facilitate heat...

01:21Masonry in Cold and Hot Weather Conditions
330
In cold weather, masonry construction requires specific precautions to ensure mortar does not freeze before curing, as this can significantly weaken its strength and watertightness. Mortar temperature should be maintained between 60°F and 80°F to support proper hydration and curing. Below 40°F, mortar water must be heated, but should not exceed 120°F as high temperatures can reduce mortar's compressive and bond strength.

01:43Thermosensation
33.7K
Peripheral thermosensation is the perception of external temperature. A change in temperature (on the surface of the skin and other tissues) is detected by a family of temperature-sensitive ion channels called Transient Receptor Potential, or TRP, receptors. These receptors are located on free nerve endings. Those detecting cold temperatures are closer to the surface of the skin than the nerve endings detecting warmth. These thermoTRP channels, while temperature selective, have relatively...

01:20Mechanisms of Heat Transfer II
4.2K
In convection, thermal energy is carried by the large-scale flow of matter. Ocean currents and large-scale atmospheric circulation, which result from the buoyancy of warm air and water, transfer hot air from the tropics toward the poles and cold air from the poles toward the tropics. The Earth’s rotation interacts with those flows, causing the observed eastward flow of air in the temperate zones. Convection dominates heat transfer by air, and the amount of available space for the airflow...
