The past decade has witnessed the rapid growth of electronic textiles with a variety textile-based smart devices being developed. However, development one-dimensional conductors that exhibit both excellent mechanical and electrical properties, while compatible conventional textile techniques, remains challenge. Herein, conductive cotton yarn was constructed using liquid metal as filler tannic acid (TA) immobilizing linker via twist-assisted deposition technique, in which eutectic gallium-indium alloy (EGaIn) droplets were effectively modified on plies by TA, followed moderate twisting. By fully utilizing internal spaces between adjacent fibers, as-prepared EGaIn-TA-yarn exhibits high conductivity, an average resistance 11.20 Ω at 10 cm length. When further wrapped shows superior wash resistance, long-term stability, flexibility. It can withstand 25 washes, 3000 bending or twisting cycles, 90 days storage ambient conditions without significant loss conductivity. cotton-wrapped could be used bendable, knottable, sewable conductor to connect light-emitting diodes (LEDs) power sources for lighting. This work provide simple, cost-effective approach developing highly yarns promising candidates replace traditional wires electronics.
