Abstract
In this paper, we measured the temperature-dependent electrical resistance of five kinds of conductive yarns for temperature-sensitive textiles. Conductive yarns for temperature-sensitive textiles are multilayered and contain copper filaments. Krifi Cu-1, 2, 3, 4, and 5 are composed of 2, 3, 4, 7, and 14 strands of the copper filament, respectively. Krifi Cu-3, 4, and 5 were covered with polyethylene terephthalate (PET) fiber for insulation. It was determined that the electrical resistance of Krifi Cu-1 and 2 increased by $40m{\Omega}$ and $27.1m{\Omega}$, respectively, with each $5^{\circ}C$ increase over the temperature range of $30-100^{\circ}C$. In addition, it was found that the temperature-dependent electrical resistance did not increase with increasing number of copper filaments. Temperature-sensitive textiles were manufactured by patterning two conductive yarns with high increment and determining the linearity of the temperature-dependent electrical resistance. For the temperature-sensitive textile patterned with Krifi Cu-2, the average electrical resistance was $71.4m{\Omega}$ but the electrical resistance was not linear with temperature. The temperature-sensitive textile patterned with Krifi Cu-2 showed an average electrical resistance of $68.6m{\Omega}$ and good linearity with temperature.
