Research on Electromagnetic Shielding Effectiveness of Composite Fabrics Made by Stainless Steel Fiber

摘要

In this paper, a kind of electromagnetic shielding fabric was introduced. The fabric was woven by composite yarns made of stainless steel fibers, cotton and polyester filaments. Using the tracer fiber technology, the internal structure of yarns and fabrics was observed through the optical microscope. Electromagnetic shielding effectiveness of the fabric was tested by FY800 electromagnetic radiation tester according to the standard of ASTM D4935-10. The optical microscope photographs show that the yarns and fabrics have many different sizes of metal grids internally. Research results show that with the increase of arrangement proportion of metallic yarns, fabric thickness and content of metallic fibers, electromagnetic shielding effectiveness of the fabric has a rising trend.
