“…However, they all did not study the influence of the stitch on the SE of the clothing. The other is the study of the interstice and hole of the fabric [5][6][7], and they explored the influence of the tiny holes formed by the intertwined yarns on the SE. The study object is the gap or hole formed by the fabric itself, and its structure is completely inconsistent with the structure of the gap and hole of the seaming stitch.…”

Abstract-The influence of seaming stitches on the shielding effectiveness (SE) of electromagnetic shielding (EMS) fabric is huge, but there is not an ideal computation model for the SE of the EMS fabric with the seaming stitch at present. This paper proposes a computation model of the SE based on the equivalent seaming gap. Firstly, a structure model of the equivalent seaming gap is constructed according to the equivalent dielectric principle. The computation method of the structural size of the equivalent seaming gap model is determined by the parameters of the stitch length, number of the stitch type, needle number, and sewing thread. A computation model of the SE based on the equivalent seaming gap structure is built according to the EMS theory. The method of the correction coefficient of the model determination is given. Finally, the samples with seaming stitches are made to test the SE using the waveguide method. The computation results with the proposed model are compared with the experimental ones. The results show that the proposed model can well calculate the SE of the EMS fabric with the seaming stitch. The study in this paper can provide a foundation for further study of the influence of seaming stitches on the SE of the EMS fabric and possesses reference significance for the design, production, evaluation and related theoretical research of the EMS clothing.

Abstract-Electromagnetic shielding (EMS) fabrics often need to design rectangular holes for application. However, there is not a mature approach to predict the shielding effectiveness (SE) of the EMS fabric with rectangular hole. This paper proposes that there are a number of loose regions of conductive fibers on the hole edge of the EMS fabric, and establishes a SE prediction model of the EMS fabric with rectangular hole. Firstly, the loose region of conductive fiber is analyzed to build a model of the rectangular hole. Secondly, the SE prediction model of the EMS fabric with rectangular hole is deduced according to the transmission coefficient of the normal region, hole region and loose region, and the determining method of the loose region is given. Finally, the prediction model is verified by experiments. The results show that the model can successfully predict the SE of the EMS fabric with the plain, twill and satin weaves, and the factors such as frequency, fabric density and metal fiber content have little influence on the model. The proposed model can provide a valuable reference for the rational design of the rectangular hole of the EMS fabric.
