“…Litz-wire based yarn shows the worst results, metallized nylon fares slightly better and tinsel-based yarn exhibits the best washability [49]. Parkova et al obtain similar results when comparing the washability of two metallized yarns and one tinsel-based yarn [40].…”

“…Even reversible effects on the protective layers can impact washability. Parkova et al argue that their silicone coating will stretch during washing, which leads to damages and function loss of embedded LEDs [40], while Gerhold observes the swelling of the PU layer on conductive textiles and suspects that this could lead to decreased conductivity [20].…”

“…Parkova et al compare silicone and TPU coating for their embroidered tracks. The results show that the less elastic TPU offers better protection than silicone, as it does not allow the underlying textile and embroidered tracks to stretch as much during washing, but uncoated tracks have the lowest washability [40]. Fu et al coat RFID antennas that are made from two different types of metallized textiles with fabric glue and moisture protection spray.…”

“…Hardy et al wash acoustic e-yarns that are integrated either into woven tubes or into sewn pockets of their textile substrates and conclude that the woven tubes offer better washing stability [22]. Similarly, Parkova et al obtain different washing results that are dependent on the integration method: when testing conductive yarns either woven or sewn into textiles, the light intensity of LEDs soldered onto the tracks decreases slower after consecutive washing cycles for the woven tracks compared to the sewn tracks [40]. Tao et al add LEDs to both sewn and woven tracks, using two different contacting methods (solder and glue), with and without silicone encapsulation.…”

E-textiles, hybrid products that incorporate electronic functionality into textiles, often need to withstand washing procedures to ensure textile typical usability. Yet, the washability—which is essential for many e-textile applications like medical or sports due to hygiene requirements—is often still insufficient. The influence factors for washing damage in textile integrated electronics as well as common weak points are not extensively researched, which makes a targeted approach to improve washability in e-textiles difficult. As a step towards reliably washable e-textiles, this review bundles existing information and findings on the topic: a summary of common failure modes in e-textiles brought about by washing as well as influencing parameters that affect the washability of e-textiles. The findings of this paper can be utilized in the development of e-textile systems with an improved washability.

“…Many studies have assessed the resistance of the conductive yarn or thread stitched onto textiles after washing or abrasion (Briedis et al, 2019;Dourado et al (2016); Eskandarian et al, 2020;Linz, 2011;Parkova & Vi, 2014;Sofronova & Angelova, 2020;Tao et al, 2017;Zaman et al,2020). However, knitted e-textiles with integrated POF and silver-coated conductive yarn are currently under-explored.…”

For the integration of conductive yarns in e-textiles, knitting offers structural versatility and malleability for wider product applications in the contexts of wearables and interiors. To enable mass adoption of conductive materials, it is imperative for users to be able to launder these materials as part of product maintenance. Interactive textiles knitted from polymeric optical fibres (POFs) and silver-coated conductive yarns are able to illuminate and change colours via integrated touch sensor systems. Current research only focuses on the washability and abrasion resistance of conductive yarns solely and not both POF and conductive yarn within the same fabric structure. This study is novel as it investigates the washability and abrasion resistance of POF and silver-coated conductive yarn integrated knitted textiles with different loop structures and the impact to their illuminative function. POFs were knitted within the same fabric structure by the inlay method using a 7-gauge industrial hand-operated flatbed knitting machine. This study examined how washing and abrasion affect POFs and silver-coated conductive yarn in five different knit structures, and the illuminative function of the knitted textiles. Washing and abrasion affected the resistance of conductive yarns. Scratches and bent POFs were observed after 20 gentle washing cycles. However, washing had minimal impact on the illuminative function of the knitted e-textiles examined in this study. The experiments provide evidence that e-textiles knitted with POFs and conductive yarns in the same fabric structure withstand washing and abrasion and thus have the potential for mass market adoption in fashion and interior applications.

Washability of e-textiles: current testing practices and the need for standardization

Washability is seen as one of the main obstacles that stands in the way of a wider market success of e-textile products. So far, there are no standardized methods for wash testing of e-textiles and no protocols to comparably assess the washability of tested products. Thus, different e-textiles that are deemed equally washable by their developers might present with very different ranges of reliability after repeated washing. This paper presents research into current test practices in the absence of e-textile-specific standards. Different testing methods are compared and evaluated and the need for standardized testing, giving e-textile developers the tools to comparably communicate and evaluate their products’ washability, is emphasized.
