The functional flexible wearable textiles have a broad application prospect in many areas. However, considering the physical and chemical effects among various additives, it is still a big challenge to prepare wearable fabrics with a balance between different properties. Herein, an

eco-friendly and multifunctional nylon/cotton blend fabric was constructed by phytic acid (PA)-induced polymerization of polypyrrole on the surface, followed by dip coating with silver nanowires (AgNWs). A high electrical conductivity of the treated blend fabrics (61 S·m?1) was obtained contributed to the excellent EMI shielding performance of nylon/cotton blend fabric (X-band ～ 38.8 dB). Meanwhile, the coating maintained the surface temperature of the fabric within a suitable range, resulting in achieving the efficient thermal management. Furthermore, the treated nylon/cotton blends achieved a remarkable reduction (83.3 % and 81.7 %) of peak heat release rate and total smoke production compared to that of the control nylon/cotton blends. In

addition, the considerable antibacterial property against E. coli and S. aureus was also realized. The successful application of this simple and eco-friendly method offered the possibility of preparing safer and more versatile wearable smart textiles.

功能性柔性可穿戴纺织品在许多领域具有广阔的应用前景。然而，考虑到各种添加剂之间的物理和化学作用，制备不同性能之间平衡的可穿戴织物仍然是一个巨大的挑战。本文以聚吡咯为原料，在聚丙烯酸（PA）表面引发聚合，然后用银纳米线（AgNWs）浸涂，构建了一种环保、多功能的尼龙/棉混纺织物。处理后的混纺织物获得了高电导率（61 S·m^?1），这有助于尼龙/棉混纺织物具有优异的EMI屏蔽性能（X波段～38.8 dB）。同时，涂层将织物的表面温度保持在合适的范围内，从而实现了有效的热管理。此外，经处理的尼龙/棉共混物的峰值放热率和总烟雾产生量分别比未经处理的降低了83.3%和81.7%
