Chemical Effects of Laundry Additives on Surface Resistivity of E-textiles

---

Abstract

Wearables have conductivity capabilities, advanced circuitry, and data communication functions. Products made with fully integrated, wearable technology is referred to as 'smart clothing' or 'smart garments.' Due to their intimate contact with the human body, wearables become soiled and must be cleaned. One of the most significant challenges of smart garments is performance reliability post-laundering. To achieve their full potential, wearable e-textiles (smart garments) must overcome these challenges to become everyday wear. In this study, the influence of select detergents and laundry additives on e-textile surface resistivity was researched. The purpose of this study was to add to the body of knowledge pertaining to e-textiles and wash conditions that may contribute to the development of appropriate smart garment care labels, thus, assisting in the preservation of the product functionality. Seven e-textiles were tested for a change in surface resistivity post-laundering condition. For each combination of e-textile + laundering condition, average resistivity was recorded. Then, the percent change was calculated and average across each chemical laundering condition. Significant discoloration was noted in e-textiles with silver-coated nylon washed in plant-based detergent. The findings of this study have helped make advancements towards understanding how e-textiles respond to laundering conditions.
