Abstract

The overall goal of this research was to evaluate wearable e-textiles in terms of their electrical integrity while they are subjected to environmental conditions and abrasion. In a previous publication (Bogan, Seyam and Slade, submitted to JOTI 2016), different woven samples of electronic improved outer tactical vest (EIOTV) with two narrow conductive traces woven in warp direction were subjected to range of temperatures and RHs, including extreme conditions. It was found that electrical resistance of networks was affected by changes in air temperature and RH and the quality of the weld had the greatest impact on electrical integrity of the conductive network, especially in more extreme environmental conditions. This part of the study dealt with the evaluation of electrical integrity of range of EIOTVs while they were subjected to two different modes of abrasion tests to simulate everyday wearing that occurs between EIOTV and standard woven abradant (using Martindale abrasion testing) and against environmental terrain such as sand (using Wyzenbeek abrasion testing). The effects of e-yarn type, number of e-yarns/trace, and weld quality on electrical integrity, assessed by increase in the network electrical resistance as the key indicator of network failure, of the EIOTVs while subjected to abrasion resistance were evaluated. The electrical resistance of all EIOTV samples remained unchanged after 50,000 cycles of Martindale abrasion testing. The results of Wyzenbeek abrasion testing showed that EIOTV fabrics from higher number of e-yarn/trace or e-yarns with higher tex-content exhibited higher electrical integrity compared to those from less number of e-yarns/trace or less tex-content.
