Although flexible and multifunctional textile-based electronics are promising for wearable devices, it is still a challenge to seamlessly integrate excellent conductivity into textiles without sacrificing their intrinsic flexibility breathability. Herein, the vertically interconnected conductive networks constructed based on meshy template of weave cotton fabrics with interwoven warp weft yarns. The two-dimensional early transition metal carbides/nitrides (MXenes), unique metallic hydrophilic surfaces, uniformly intimately attached preformed fabric via spray-drying coating approach. Through adjusting cycles, degree interconnectivity precisely tuned, thereby affording highly breathable integrated Joule heating, electromagnetic interference (EMI) shielding strain sensing performances. Interestingly, triggered by architecture, MXene-decorated low loading 6 wt % (0.78 mg cm-2) offer an outstanding electrical 5 Ω sq-1. further endows superior heating performance temperature up 150 °C at supply voltage V, EMI performance, sensitive responses human motion. Consequently, this work offers novel strategy versatile design devices.
