Abstract: In the paper, the relation between two kinds of blended knitted fabrics’ volume resistance, surface resistance and electrode pressure was investigated. The experiment results showed that: electrode pressure has great influence on the measurement of electric resistance of the fabrics. when slightly contact, there is a larger contact resistance between the electrode and the fabrics, and with the increase of electrode pressure,

the knitted fabric’s surface and volume resistance reduces; according to surface resistance, resistance variation of stiff and compact knitted fabric is smaller than that of fluffy and loose knitted fabric, while according to volume resistance, resistance variation of the stiff compact knitted fabric is slightly faster than that of the fluffy and loose knitted fabric. At the same time with electrode pressure increases further, the

reducing amplitude of volume and surface resistance slow down. Variation of the fabric resistance has close relationship with fabric compressing performance.

Key words: knitted fabric; three electrode; pressure; electric resistance
