The integration of electronic components in/onto conductive textile yarns without compromising textile qualities such as flexibility, conformability, heat and moisture transfer, and wash resistance is essential to ensuring acceptance of electronic textiles. One solution is creating flexible and stretchable conductive yarns that contain tiny surface-mounted electronic elements embedded at the fiber level. The purpose of this work was to manufacture and subsequently evaluate the physical features and electromechanical properties of stainless steel yarn with light-emitting surface mounted devices (SMDs) embedded in it. The SMDs were successfully integrated into a conductive stainless steel yarn (SS) by inserting crimp beads and creating a bond through hot air soldering machines, resulting in what we call an E-yarn. The relationship curves between gauge length and electrical resistance, and the relationship curves between conductive yarn elongation and electrical resistance, were explored experimentally. The results of the analysis demonstrated that E-yarn had a lower tensile strength than the original electrically-conductive SS yarn. The effects of the washing cycle on the conductivity of the E-yarn were also investigated and studied. The results showed that E-yarns encapsulated at the solder pad by heat shrink tube still functioned well after ten machine wash cycles, after which they degraded greatly.
在不影响诸如柔韧性、贴合性、热湿传递和耐洗性等纺织品质的前提下，将电子元件集成到导电纺织纱线中或纱线表面，对于确保电子纺织品被接受至关重要。一种解决方案是制造包含在纤维层面嵌入微小表面贴装电子元件的柔性且可拉伸的导电纱线。这项工作的目的是制造并随后评估嵌入发光表面贴装器件（SMD）的不锈钢纱线的物理特性和机电性能。通过插入压接珠并利用热风焊接机形成连接，SMD被成功集成到导电不锈钢纱线（SS）中，从而得到我们所称的电子纱线（E纱线）。通过实验探究了标距长度与电阻之间的关系曲线，以及导电纱线伸长与电阻之间的关系曲线。分析结果表明，E纱线的拉伸强度低于原始的导电SS纱线。还研究了洗涤循环对E纱线导电性的影响。结果显示，通过热缩管在焊盘处封装的E纱线在经过十次机洗循环后仍能良好运行，之后其性能大幅下降。
