Abstract：Inordertoachievetheefectivecombinationofthetriboelectriclayerandtheelectrodeintextilebasedtriboelectric nanogenerators （TENG），the core-spun yarns with polyimide（PI）or polyphenylene sulfide（PPS）as triboelectric material and stainless-steel yarnas electrode were prepared using conjugate-electrospinning orcontinuoushollow spindle fancy twisting technology.Then，the triboelectric fabricswith full weft were prepared by weaving processin which thecore-spun yarns served asthe weft yarns.The efectoffriction layer microstructure on the performance of the TENG，the working adaptabilityof the TENG in high-temperature environment，and the practical application performance of the fabric based TENG were investigated.The results show that when PPS staple fiber core-spun yarn based fabric and PI nanofiber core-spun yarn based fabric were respectively the positive and negative triboelectric layers of the TENG，because of the effective matching between micro-and nano-fibers to increase the efective working area，the fabric based TENG showed the optimum triboelectric properties，and it could maintain stable operation in a high-temperature environment below 200 C .When the load resistance was 20MΩ ，the TENG has a power density of 0.67W/m2 and could light up 18 COBs or 140 LEDs，or charge capacitors to further power calculators，demonstrating its potential applications in the field of powering wearable microelectronics.
