Shield effect of functional interlining fabric

Electromagnetic interference (EMI) have become very serious in a variety of different electronic equipment such as personal computers (frequency at several GHz), mobile devices (0.9 - 2.4 GHz) and similar. This imposes the need of setting boundaries for EM emission of electric and electronic devices in order to minimize the possibility of interference with radio and wireless communications. Functional textiles can offer protective properties against electromagnetic (EM) radiation. The aim of this study was to investigate the degree of protection against electromagnetic radiation of polyamide copper coated interlining fabric before and after dry cleaning treatment. Electromagnetic protection efficiency of the interlining functional fabric is explored on both sides at the frequencies of 0.9 GHz ; 1.8 GHz ; 2.1 GHz and 2.4 GHz. The results obtained have shown that the interlining fabric has good protective properties against electromagnetic radiation, but after dry cleaning treatment reduction is observed. SEM micrographs of the interlining surface confirms shield effect decline due to degradation and firing of the copper layers during the process of dry cleaning.
