Electromagnetic shielding effectiveness of stainless steel/polyester wovenfabrics

This paper presents a preliminary study of the development of stainless ste el/polyester woven fabrics for electromagnetic shielding applications. To f acilitate weaving of stainless steel wires and to reduce material costs, in itially blended yarns of stainless steel and polyester staple fibers are pr oduced by a ring spinning method, then woven into a variety of structures. Using a coaxial transmission set-up, the electromagnetic shielding effectiv eness (EMSE) of these fabrics is determined in the frequency range of 300 k Hz to 3 GHz. Variations of EMSE with the woven structures, number of layers , and blend ratio of stainless steel to polyester in the yarns are describe d. The new textile material may be suitable for shielding home electronics and electrical appliances from electromagnetic fields.
