In this paper, the relation between the resistance and the temperature of Stainless Steel (SS) and its fabric are studied. It is found that the resistance of Stainless Steel (SS) fiber has a positive linear relationship with temperature, and that of SS fabric has a negative linear relationship with temperature within a definite range. The textile structure is useful to increase the sensitivity and accuracy of the temperature sensing. The main mechanism of the fabric sensing has been deduced to be the change of the contact resistance between yarns during temperature changing.
