Abstract
The protective shield effectiveness (SE) of copper-coated polyamide and polyester interlining fabrics at frequen¬cies of 1.8 GHz, 2.1 GHz and 2.4 GHz are presented in this study. These fabrics were treated through 10 cycles of dry and wet cleaning. After the characterization of shield effectiveness, fabrics were stored in a dark and dry place. On the basis of the SE values at all measured frequencies, it was confirmed that the copper-coated protective polyester fabric had better SE durability under storage conditions than the copper-coated polyamide fabric. Accordingly, the copper-coated polyester interlining fabric is more suitable for integration into functional clothing due to its use cycle.
Highlights
Mobile technology has made significant progress in recent decades and it is difficult to imagine everyday activities and tasks without mobile phones, tablets and laptops
The research in this paper focused on monitoring the durability of shield effectiveness (SE) of the S1 and S2 copper-coated interlining fabrics, the purpose of which is protection against electromagnetic microwave radiation
The results of the effectiveness of the SE protection of the face and back side of the tested protective interlining fabrics before and after 10 cycles of professional care, and after storage in a dark room are presented in Tables 3 and 4, and Figure 3
Summary
Mobile technology has made significant progress in recent decades and it is difficult to imagine everyday activities and tasks without mobile phones, tablets and laptops. The intensive technological development of new electric and electronic devices and gadgets resulted in demand for increased control of technology’s negative impact and a way to prevent that impact. This is why limits on EM emissions for all electric and electronic devices were set to minimise the possibility of radio and wireless communications interfering with human and other organisms. The intensive development of textile products with EM shield effect properties has attracted considerable interest of researchers, and the textile and garment industries, which have been trying to manufacture woven and knitted fabrics, as well as garments with EM shield effect properties [6−8]. The impact of 10 cycles of professional care processes, dry and wet cleaning, and storage time over a period of seven years on SE properties was evaluated at frequencies 1.8 GHz, 2.1 GHz and 2.4 GHz
