Textile-based heaters have opened new opportunities for next-generation smart heating devices. This experiment presents electrically conductive textiles for heat generation in orthopaedic compression supports. The main goal was to investigate the influence of frequent washing and stretching on heat generation durability of constructed compression knitted structures. The silver coated polyamide yarns were used to knit a half-Milano rib structure containing elastomeric inlay-yarn. Dimensional stability of the knitted fabric and morphological changes of the silver coated electro-conductive yarns were investigated during every wash cycle. The results revealed that temperature becomes stable within two minutes for all investigated fabrics. The heat generation was found to be dependent on the stretching, mostly due to the changing surface area; and it should be considered during the development of heated compression knits. Washing negatively influences the heat-generating capacity on the fabric due to the surface damage caused by the mechanical and chemical interaction during washing. The higher number of silver-coated filaments in the electro-conductive yarn and the knitted structure, protecting the electro-conductive yarn from mechanical abrasion, may ensure higher durability of heating characteristics.
基于纺织品的加热器为下一代智能加热设备带来了新机遇。本实验展示了用于骨科加压支撑物中发热的导电纺织品。主要目标是研究频繁洗涤和拉伸对所构建的压缩针织结构发热耐久性的影响。使用镀银聚酰胺纱线编织一种含有弹性体镶嵌纱的半米兰罗纹结构。在每个洗涤周期中研究针织物的尺寸稳定性和镀银导电纱线的形态变化。结果表明，所有研究的织物在两分钟内温度就会稳定下来。发现发热取决于拉伸，主要是由于表面积的变化；在开发加热压缩针织品时应予以考虑。洗涤会对织物的发热能力产生负面影响，这是由于洗涤过程中的机械和化学相互作用导致表面受损。导电纱线和针织结构中镀银长丝数量越多，能保护导电纱线免受机械磨损，可能确保加热特性具有更高的耐久性。
