Abstract: As a kind of high performance fibers, the silver-plated fiber has wide application prospects. This paper has knitted four different structural kinds of silver-plated filament knitted fabrics: plating jersey structure, plating 1+1 rib structure, plating full needle structure and land-in structure. With the analysis of fabric's heating effect after electrifying, the land-in structure has been adopted. The result of testing the electric heating performance of silver-plated filament land-in structure shows that after electrifying, the temperature of fabric rose and finally reached the stable state. The input power was related with the stable temperature rise linear. The fabric had a better thermal stability, and the surface temperature was well distributed.

Key words: silver-plated knitted fabric, knitting method, thermal stability, electric heating temperature rise performance, uniformity of surface temperature
