Electrospinning Machine| Sustainable Bi-directional thermoregulationfabric for clothing microclimate

Challenge: Maintaining the balance of clothing microclimate is crucial for human health management. Ideal smart textiles should possess key properties such as active temperature regulation, moisture permeability, and stable working performance. However, structures incorporating all these functions are rarely reported.

Approach: A team led by Professor Ding Bin and Professor Wang Xianfeng from Donghua University reported a sustainable and durable bidirectional thermoregulating fabric (Bi-DTF) through a hierarchical structure engineering strategy. This advancement stems from the programmability of molecular chains, aiming to reduce chain aggregation, improve functional particle compatibility, and construct a dynamic stress dissipation network, thereby fully enhancing the robustness of the composite fiber membrane.

Innovation 1: The optimized Bi-DTF significantly eliminates thermal/cold stimuli caused by environmental changes, with a high energy storage density (4.1 kJ m−2), maintaining stable working performance even after 50 standard washes and 500 friction cycles.

Innovation 2: Compared to commercial textiles, the maximum thermal temperature difference of Bi-DTF during heating and cooling cycles is only 2.3°C, with a cooling temperature difference of 2.6°C.
