ABSTRACT:
A process and system of producing conductive yarns in use for info-communication and conductive yarns produced thereby, in which the conductive yarns are produced using metal filaments. The process includes the steps of feeding a plurality of metal filaments, heating the plurality of metal filaments to soften the plurality of metal filaments, drafting the plurality of metal filaments and cutting the plurality of metal filaments into a plurality of slivers having a predetermined length, drawing and twisting the plurality of slivers into a yarn, winding the yarn on a bobbin, coating the yarn with a waterproof material and an electromagnetic shielding material in a thin film while unwinding the yarn from the bobbin, and drying the yarn, and covering the yarn with a textile yarn.
