Comprehensive performance of compound fabrics in terms of electromagnetic shielding and wearability based on the Euclid approach degree of fuzzy matter elements

摘要

In this study, we designed electromagnetic shielding fabrics (EMSFs) that consist of composite yarn containing stainless steel fibers. Ten EMSFs with different metal fiber contents and metal grid sizes were examined as research specimens, and tests were conducted to determine electromagnetic shielding effectiveness (EMSE) and wearability indices. The indices were analyzed and the comprehensive performances of the EMSFs evaluated with the fuzzy matter-element method. Experimental results show that the EMSE improved and fabric wearability worsened when metal fiber content increased and metal grid size decreased. Moreover, fuzzy matter-element evaluation findings suggested that the best comprehensive performance was observed in the composite fabric containing 11.71% metal and whose metal mesh measures 1.41mm(2); these features reflect the maximum Euclid approach degree.
