An evaluation and characterization study of knitted fabrics for use as telecommunication device substrate

Abstract

This work aims to characterize and evaluate the textiles and electrical properties that have a vital impact on weft knitted for use as substrates applied to telecommunications devices. There are several applications where flexible devices are required, for example when devices are contained in technical uniforms or technical textiles garments. So, to understand the characteristics of the substrate for use in antennas, therefore, it is necessary to characterize the different types of blended knitted (100% Cotton, 50% Cotton/50% Polyester, 50% Cotton/50% Spandex and 50% Cotton/50% Polyamide) to indicate the composition of blended Jersey structures that exhibited significantly better properties for application in E-textiles. Although the knitted fabrics studied in this article are developed for conventional applications, their real permittivity and loss tangent are satisfactory for use in applications as a substrate and the differences between values in each knitted fabric can be linked to the composition (CO, CO + PES, CO + PUE and CO + PA) studied.
