METHOD FOR MANUFACTURING CONDUCTIVE METAL COMPLEX FIBER HAVING INCREASED YIELD STRENGTH, CONDUCTIVE METAL COMPLEX FIBER MANUFACTURED THEREBY, AND EMBROIDERED CIRCUIT PRODUCT MANUFACTURED BY USING CONDUCTIVE METAL COMPLEX FIBER

摘要

The present invention relates to a method for manufacturing a conductive metal complex fiber which can be applied to a smart textile made by combining technologies of electricity, electronics and IT and electronic circuit technology made by fibers; a conductive metal complex fiber manufactured thereby; and an embroidered circuit product manufactured by using the conductive metal complex fiber. More specifically, the present invention relates to a method for manufacturing a conductive metal complex fiber having a conductive fiber of an increased yield strength by collecting multiple pieces of a first twisted yarn twisted after a thread and a conductive fiber are wound in a state of being covered, and by winding the thread on a surface of the first twisted yarn in a state of being covered in an opposite direction of a twisting of the first twisted yarn; a conductive metal complex fiber manufactured thereby; and an embroidered circuit product manufactured by using the conductive metal complex fiber. The method of manufacturing a conductive metal complex fiber having an increased yield strength according to the present invention, comprises: a first process for manufacturing a wound fiber by winding thread with a conductive fiber in a covered state; a second process for manufacturing a first twisted yarn by twisting the wound fiber by the first process; and a third process for manufacturing a reinforced fiber having an increased yield strength of a conductive fiber by winding the thread in a covered state on the surface of the multiple pieces of the first twisted yarn by the second process.
