Dynamic Thermal-Regulating Textiles with Metallic Fibers Based on a Switchable Transmittance

A review on emerging developments in thermal and moisture management by membrane‐based clothing systems towards personal comfort

“…A dynamic IR‐gating fabric towards controlling IR transmission in response to the climatic conditions has been also fabricated using metal‐coated monofilaments and stimuli‐responsive polymer actuator beads. With control of thermal radiation's wide‐band transmission, these smart structures cause the wearer to feel comfort in surrounding temperatures ranging between 9.5 and 25.7°C 85 …”

“…84 A dynamic IR-gating fabric towards controlling IR transmission in response to the climatic conditions has been also fabricated using metal-coated monofilaments and stimuli-responsive polymer actuator beads. With control of thermal radiation's wide-band transmission, these smart structures cause the wearer to feel comfort in surrounding temperatures ranging between 9.5 and 25.7 C. 85 Graphene-and carbon nanotube-based membranes by electrical gating have paved the way for developing and producing active mid-IR radiative cooling membranes. A scalable roll-to-roll process was considered by Sun et al 86 to fabricate a sandwich-structured membrane based on multiwalled CNTs (MWCNTs) with long-term stability and adjustable radiative cooling performance.…”

A numerical approach to evaluate the personal radiative thermal management of textiles part one: Mid-infrared transmittance, reflection and absorption

“…Human skin, as an excellent mid-infrared (MIR) emitter (emissivity = 0.98) can emit MIR radiation in the wavelength range between 7 and 14 μm, with the peak emission at 9.5 μm at the normal skin temperature of 35 • C. As a passive, effective, and renewable way of decreasing the cooling energy requirements without power input, radiative cooling has attracted considerable attention in the field of energy-saving applications such as energy-efficient buildings, enhanced solar cells, electricity generation, and water harvesting [5]. Apart from these, several cooling textiles have been developed to promote the use of radiative cooling materials for personal cooling [6][7][8][9][10][11][12].…”

“…Much of the current research on the optical performance of the textile structure has paid particular attention to either the UV [20,21,24] or far-infrared [25] wavelength range. According to their findings, there are many factors that influence the optical properties of textiles, including the fibre type [6,7,23], fibre cross-section [25,26], fibre diameter, yarn diameter, and textile porosity [6,11,27,28]. Therefore, the structural parameters of the textile are key variables that affect the light path for the reflection, emission, and transmission.…”

In Situ Formation of SiO2 Nanospheres on Common Fabrics for Broadband Radiative Cooling

“…Traditional fabrics can only passively prevent body heat loss from the body to the external environment to maintain human body temperature or passively block strong sunlight to protect human body skin from sunburn. Radiative cooling fabrics can adjust human body temperature in two ways, one is to increase the transmittance of the fabric in the human thermal radiation band, which is beneficial to dissipate heat from the human body to the surrounding environment; the other is to increase the emissivity of the fabric in the atmospheric window and thus can radiate human body heat to outer space actively. − Yang et al − have carried out a lot of research on radiative cooling fabrics. They made use of the optical properties of polyethylene (PE) and performed a series of processes on PE textile to obtain radiative cooling fabrics.…”
