To achieve durable printed circuits on textiles, it is necessary to print low-cost polymer films that interface the fabric with the printed circuit. The film smooths the surface of the fabric to enable the printing of thin and flexible conductive films on the fabric. When printed, the thickness of the polymer films can dominate the fabric and limit the flexibility of the printed e-textile. This paper investigates the reduction of the polymer film thickness for printed and wearable e-textiles by controlling the thread count of the fabric using different blends of polyester/silk/cotton fabrics. A 50 µm thick polyurethane interface layer with a surface roughness, Ra value of 1.7 µm is reported on a 100% plain weave polyester fabric. The PU thickness is 4 times less than the state of the art and shows more than 80 % reduction in the proportion of interface material to fabric thickness of the printed e-textile. This minimizes the impact of the printed film on the fabric.

本数据集支持Komolafe A.、Nunes-matos H.、Glanc-Gostkiewicz M.与Torah R.于2020年发表的《纺织结构对印刷电子纺织品（printed e-textiles）穿戴性能的影响》一文的相关研究。为在纺织品上制备耐用的印刷电路，需采用低成本聚合物薄膜作为织物与印刷电路的界面层。该薄膜可平整织物表面，从而实现薄且柔性的导电薄膜在织物上的印刷。但在印刷过程中，聚合物薄膜的厚度会对织物特性产生主导性影响，进而限制印刷电子纺织品的柔性。本研究通过调控聚酯/蚕丝/棉混纺织物的纱线密度，探究了可穿戴印刷电子纺织品的聚合物薄膜厚度优化方案。实验表明，在100%平纹织造聚酯织物上可制备厚度为50μm、表面粗糙度Ra值为1.7μm的聚氨酯（polyurethane）界面层。该聚氨酯界面层的厚度仅为当前主流技术水平的1/4，同时使印刷电子纺织品的界面材料占织物厚度的比例降低了80%以上，从而最大程度降低了印刷薄膜对织物性能的影响。
