Abstract

E-textiles; new emerging hybrid systems and devices require novel standards regarding their reliability and durability in order to gain the attraction and satisfaction for the customers and market readiness. Launderability of e-textiles is one of the key problems for their reliability and maintenance. Standards should fulfill the requirements for both: the textile and electronic parts of e-textile products. In this article, an analysis of water and detergent influence on the conductive yarns which are generally used as a connection in e-textile products is investigated. During the washing process various stresses (mechanical, temperature, chemical, etc.) damage the connection elements such as electrically yarns that make all together a textile circuit board (textile motherboard). All those stresses are moreover interdependent. Water or chemical stresses are supposed to be strongly damaging and should be discussed in details. During the washing procedure it is important to understand the water and detergent effects on the conductive yarns. Therefore, experimental studies are conducted by dipping conductive yarns in those solutions and by extended characterization. Structural changes of yarns are tested by FTIR-ATR, and peaks before and after dipping in the solutions were noted. Results point out the level of damage on the yarn surface caused by chemical stresses due to dipping in solutions. Furthermore, yarn surfaces were analyzed with optical microscopy. Remaining solutions after removing the dipped yarn were also analyzed by UV-Visible Spectroscopy to check any possible removal of silver coating from the yarn into solution, due to water or water detergent solutions. UV-Visible Spectroscopy validated our results obtained by FTIR-ATR peaks. By these experiments, time duration e-textiles can withstand in liquid solution without any loss of conductivity can be evaluated and predicted.

水和化学应力对镀银聚酰胺纱的影响

抽象的

电子纺织;新兴的混合动力系统和设备在可靠性和耐用性方面需要新颖的标准,以赢得客户的青睐和满意,并为市场做好准备。电子纺织品的可洗性是其可靠性和维护的关键问题之一。标准应同时满足以下要求:电子纺织产品的纺织品和电子部件。在本文中,分析了水和清洁剂对通常用作电子纺织产品连接件的导电纱的影响。在洗涤过程中,各种应力(机械应力,温度,化学作用等)会损坏连接元件,例如电纱,它们共同构成一个纺织电路板(纺织母板)。所有这些压力都是相互依存的。水或化学应力可能会造成严重破坏,应进行详细讨论。在洗涤过程中,重要的是要了解水和清洁剂对导电纱的影响。因此,通过将导电丝浸入这些溶液中并进行扩展的表征来进行实验研究。纱线的结构变化通过FTIR-ATR测试,并且在浸入溶液之前和之后都出现了峰值。结果指出了由于浸入溶液中而产生的化学应力对纱线表面造成的损害程度。此外,用光学显微镜分析纱线表面。还通过紫外-可见光谱法分析了除去浸渍纱之后的剩余溶液,以检查由于水或水清洁剂溶液而将银涂层从纱线上除去的任何可能的溶液。紫外可见光谱验证了我们通过FTIR-ATR峰获得的结果。通过这些实验,可以评估和预测电子纺织品在液体溶液中的持续时间,而不会损失任何导电性。
