Abstract:

In this paper, the standard test method of fabric shielding effectiveness was simply introduced in order to understand systematically the influence of fabric structure of stainless steel fiber on the shielding effectiveness. The different fabrics were woven using of stainless steel monofilament cotton yarn, stainless steel multifilament cotton yarn and stainless steel fiber cotton yarn. Then shielding effectiveness of these fabrics was measured. Results show that spacing between the stainless steel filaments has a great influence on the shielding effectiveness. The shielding effectiveness of fabric will reduce in a certain range when distance of stainless steel filaments is lengthened. Then shielding effectiveness of blended fabric will increase with increasing of the content of stainless steel fiber. The shielding effectiveness of duplex stainless steel filament fabrics is much better than unidirectional stainless steel filament fabric. Under the same testing condition the shielding effectiveness is different between stainless steel monofilament blended fabric and stainless steel multifilament blended fabric. The structure of stainless steel blended yarn has a great effect on shielding effectiveness of shielding fabric, the shielding effectiveness of stainless steel fiber blended fabric is better than the stainless steel filament blended fabric because the content of stainless steel fiber is difference between two kinds of yarn structure.
