Abstract(s) :

(Anglais) Radiative heat management for personal comfort using photonic engineered textiles can provide a substantial advantage for an energy-efficient and sustainable society. We propose a Janus-yarn design approach for a dual-mode, double-sided thermoregulating fabric: a passive radiative management textile using asymmetric yarn composition, leading to dual emissivity characteristics. The fabric provides both passive cooling and heating functions by wearing the textile inside-out. A tailored combination of reflective and absorptive structures leads to a substantial emissivity asymmetry between the two surfaces of the fabric.
