ABSTRACT
The aim of this work was to
investigate the electrical resistance change of electro-textiles manufactured
using cotton fabrics with stainless steel and silver plated PA yarns
incorporation after being subjected to home laundering, i.e. detergent
washing and silicone softening. Electrical resistances
of conductive yarns inside the fabric structure were compared and
discussed statistically before and after washing and softener application. Greatest
changes in electrical resistances were observed with samples including silver
plated PA yarns. After five washing cycles with detergent, silicone
softening agent is removed from yarns by washing, and thus conductivity
increases. Further washing of e-textiles with detergent for five more cycles
causes decrease in conductivity, because of chemical effects of detergent and
mechanical effects of washing process such as abrasion due to friction. Detergent
which has negative reactive sites bonds with metal ions reduces conductivity.
