Benefits of technology

This patented technology allows for more efficient use of electricity by utilizing multiple modes of operation (active or passively) within one piece of cloth instead of requiring separate devices like resistors that are bulky and require maintenance). Additionally, this technology has been developed with different materials and shapes being added into it to achieve better performance without increasing its weightiness.

Problems solved by technology

This patented technical problem addressed in this patents relates to improving the warmth retention performance (hotness) of current heatings made from flexible wires attached at one layer inside another fabric, which makes them hard to fit around curved areas like chests without losing their effectiveness due to reduced thicknesses caused by the added weight of these wires themselves. Additionally, they lack durability when exposed repeatedly during usage over long periods of time because they lose some energy quickly after being worn out too much.

Abstract

The invention relates to a multi-mode flexible textile-based active heating intelligent fabric and a preparation method thereof. The intelligent fabric comprises an active heating fabric layer and a phase change heat storage layer, the active heating fabric layer comprises base cloth, silver-plated conductive yarns, a direct-current power supply and an electrode, the silver-plated conductive yarns are arranged on the base cloth, and the direct-current power supply drives the silver-plated conductive yarns to perform Joule heating through the electrode; the phase change heat storage layer is used for absorbing and storing heat of the active heating fabric layer when the external environment temperature is higher than a temperature threshold value and releasing the stored heat to the active heating fabric layer when the external environment temperature is lower than the temperature threshold value. Joule heating is carried out through the silver-plated conductive yarn, and the heating rate is high; large-area heating can be realized by adjusting the area of the silver-plated conductive yarns; in addition, through the supercooling characteristic of a phase change material in the phase change heat storage layer, heat dissipation is slowed down, the active heating time is prolonged, and energy consumption is reduced.
