Abstract: In this paper, the shielding mechanism of electromagnetic shielding fabric was simply introduced to explain the influence of bedded form of silver-plated filament in the fabric on the shielding effectiveness. Then the different bedded models were constructed and the shelf was designed to roll the filament based on the bedded model. The shielding effectiveness of these models was measured according to the standard plain material's testing method of the shielding effectiveness. Results show that when the bedded models are different there are significant changes of the shielding effectiveness. Under the same testing condition the shielding effectiveness of the model in which the yarns were arranged at right angle and kept conducted was the best, while the model, in which the yarns were arranged in parallel, was the worst. And the arrange density of the yarns in the model influenced the shielding effectiveness significantly. It can be concluded that there is a power function between the diagonal length of the grid in the model of two contact sets of yarns arranged at right angle and the shielding effectiveness of the samples, and the shielding effectiveness decreased with the increase of the diagonal length.
