전도사를 활용한 발열 니트의 제조 및 발열특성에 관한 연구 = Study on the Fabrication and Heating Properties of Heating Knitted Fabrics Based on Conductive Yarn

다국어 초록 (Multilingual Abstract)

In this study, the heating and electrode parts were knitted in one step using the intarsia technique while knitting heated knitted fabrics based on conductive yarn. The parallel structure possesses eight-line heating and electrode parts on both sides, which were designed to be knitted only with conductive yarn. Eight types of knitted fabrics were prepared based on the knitting principle and density of the electrode part, and their electrical and heating properties were considered. There was no issue of disconnection in the process of repeated and long-term experiments. The resistance along the course and wale directions of the electrode part knitted with high-density miss stitch was the lowest. When 6 V was applied, the heating temperature of knitted fabrics was maintained up to 62.7 ℃. The heating temperature could be controlled according to the voltage. In addition, the miss-stitch-based electrode structure with high density exhibited a smaller deviation in temperature than other structures, considering the center of the eight heating lines at 64.7 ℃ and the edge line at 53.5 ℃. Moreover, the heating rate was increased, and the time to reach the normal temperature was decreased. The knitting principle of the electrode part of the heating knitted fabric designed in this study more significantly affected the temperature change than the knitting density.
