In parallel with the technological developments, electronic systems can be placed easily on to textile based flexible fabric surfaces. It can be estimated that there is an increase of the usability of electrotextiles in the near future with the production expansion and the increasing demand of such products. It's essential that, the in-use performances should be investigated in order to evaluate daily usage of the electrotextiles. In this study the transmission performances of electrically conductive yarns, as one of the essential materials of electrotextiles, are evaluated. Within the study, in order to observe the effect of cleaning processes on the electroconductivity characteristics of textile based conductive pathways, the repeated washing cycles and conventional dry-cleaning processes are investigated comparatively.
