▎ 摘　　要

NOVELTY - Manufacturing conductive yarn comprises preparing aqueous solution of poly(diallyldimethylammonium chloride), soaking the cotton thread in the aqueous solution, taking out the cotton thread from the aqueous solution and drying, preparing conductive material solution, and performing ultrasonic treatment of the conductive material solution, soaking the dried cotton thread in the ultrasonically-treated conductive material solution, taking out the cotton thread from the conductive material solution and drying. USE - The conductive yarn is useful in multi-point myoelectricity collecting sleeve for prosthesis interaction system (all claimed). DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for the conductive yarn manufactured by the method.
