更广泛地采用电子纺织品需要将小型电子元件集成到纺织品中，而不影响纺织品的质量。一种解决方案是创建一种柔性纱线，其将电子组件并入纱线的纤维内（E-纱线）。这些新型E-纱线的生产最初是一种工艺技术，在纱线纤维中加入包装模具需要大约90分钟。这里描述的研究表明，通过自动化制造过程，可以在工业规模上生产E-纱线。这涉及调整印刷电路板制造技术和纺织纱线包覆机械。生产过程始于将封装芯片回流焊接到精细的多股铜线上。然后将载体纱线与铜线平行放置以提供拉伸强度。然后将封装管芯和相邻的载体纱线封装在聚合物微荚中，以提供保护，防止水分进入以及管芯和焊点上的机械应变。然后，通过用额外的纤维包围微荚和铜互连件来完成该过程，所述额外的纤维与针织纤维护套紧密地保持在一起。这种原型自动化生产工艺将一个微型设备嵌入纱线的时间缩短到6分钟，从而提高了生产速度，证明了电子纱线生产工艺的自动化是可行的。原型服装已经创建使用电子纱线.进一步的发展可以包括将纱线组分从一个生产阶段自动转移到下一个生产阶段，从而能够更大地提高E纱线的制造速度。
Wider adoption of electronic textiles requires integration of small electronic components into textile fabrics, without comprising the textile qualities. A solution is to create a flexible yarn that incorporates electronic components within the fibres of the yarn (E-yarn). The production of these novel E-yarns was initially a craft skill, with the inclusion of package dies within the fibres of the yarn taking about 90 min. The research described here demonstrated that it is possible to produce E-yarns on an industrial scale by automating the manufacturing process. This involved adapting printed circuit board manufacturing technology and textile yarn covering machinery. The production process started with re-flow soldering of package dies onto fine multi-strand copper wire. A carrier yarn was then placed in parallel with the copper wire to provide tensile strength. The package die and adjacent carrier yarn were then encapsulated in a polymer micro-pod to provide protection from moisture ingress and from mechanical strain on the die and solder joints. The process was then completed by surrounding the micro-pod and copper interconnects with additional fibres, held tightly together with a knitted fibre-sheath. This prototype, automated production process reduced the time for embedding one micro-device within a yarn to 6 min, thus increasing the production speed, demonstrating that automation of the E-yarn production process is feasible. Prototype garments have been created using E- yarns. Further developments can include automated transfer of the yarn components from one stage of production to the next, enabling greater increases in speed of manufacture of E yarns.
