Electromagnetic shielding mechanisms using soft magnetic stainless steel fiber enabled polyester textiles

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.

Stainless Steel Fiber

This study used the DR-SO4 window method to test the shielding effectiveness of silver-plated fiber functional fabric, copper–nickel duplicate coating fabric, and stainless steel fiber-blended-type fabric. These electromagnetic shielding fabrics exhibited different levels of shielding effectiveness under different polarization directions. In the same frequency, the shielding effectiveness difference between the vertical polarization wave direction and horizontal or 45° polarization wave direction is higher in silver-plated fiber functional fabric and copper–nickel duplicate coating fabric than that in stainless steel fiber-blended fabric. The radiation distance of 1.5 m has great influence on the shielding effectiveness of the three fabrics. These fabrics show a repeated and intersected change in wrinkle degrees of 1# and 2#. The fabrics in the wrinkle degree of 2# have higher shielding effectiveness than that of 3#. The wrinkle recovery properties of electromagnetic shielding fabrics also affect their shielding effectiveness. The shielding effectiveness of copper–nickel duplicate coating fabric with low wrinkle recovery property considerably changes. This research provides a basis for the design of electromagnetic shielding fabrics.
