不锈钢纤维及其织物的电阻与温度关系研究

A Study on Relation between Resistance and Temperature of Stainless Steel Fiber and Its Fabric

摘要:

研究了不锈钢纤维及其织物的电阻与温度之间的关系。通过实验观察到不锈钢纱线电阻随温度增加而线性增加，不锈钢织物的电阻随温度增加而下降，且在一定范围内成线性关系，并大大提高了其电阻变化的灵敏度。织物电阻随温度变化的机理主要是温度变化过程中纱线间接触电阻的变化引起织物电阻的相应变化。

Abstract:

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.
