Textiles are not only used for clothing but also have found applications in many other areas. Textiles fulfilling functional or technical properties are called “technical textiles.” Incorporation of conductive components, sensors, or materials reacting to environmental influences convert those into so-called “smart textiles.” Common methods of applying conductive tracks to textiles are embroidery, which can cause damage to the textile, or printing of a low-conductivity paste that may include toxic chemicals. A new method of applying electrical conductors to textiles for contacting is laser welding. In this process, a thin metal foil is welded on locally with an absorber placed above the metal foil to ensure that sufficient energy is applied to partially melt the textile underneath the metal foil. One variant for welding conductive tracks is the use of a globo-optics and a diode laser system with a wavelength of 975 nm. With these optics, the glass sphere focuses the laser beam and serves as a mechanical pressure tool for achieving a zero gap between fabric and foil. Parameters that are varied are the processing speed and the laser power receiving different track widths, as well as the type of textile. In this work, their influence is evaluated by microscopy, electrical resistance measurements during Martindale tests for abrasion resistance, and tensile tests. The investigations clarify the durability and utility of welded conductive tracks on textiles. It is possible to produce conductive tracks out of beaten copper joined on textiles using laser radiation showing conductivity after 10,000 abrasion cycles. The tensile strength of textiles totally made of thermoplastics is more influenced by the heat input of the laser than blended textiles, but their abrasion resistance is worse. Furthermore, an outlook on the possibility of welding using a laser source with a wavelength of 450 nm (blue laser) and a scanner as optics will be given.

纺织品不仅用于服装，而且在许多其他领域都有应用。满足功能或技术特性的纺织品被称为“技术纺织品”。结合导电元件、传感器或对环境影响做出反应的材料，将它们转化为所谓的“智能纺织品”。在纺织品上施加导电迹线的常见方法是刺绣，这可能会损坏纺织品，或者印刷可能包含有毒化学物质的低电导率浆料。将电导体应用到纺织品上进行接触的一种新方法是激光焊接。在此过程中，薄金属箔被局部焊接，吸收器放置在金属箔上方，以确保施加足够的能量来部分熔化金属箔下方的纺织品。焊接导电轨道的一种变体是使用球形光学器件和波长为 975 nm 的二极管激光系统。借助这些光学器件，玻璃球会聚焦激光束并充当机械压力工具，以实现织物和箔片之间的零间隙。不同的参数包括处理速度和接收不同轨道宽度的激光功率以及纺织品的类型。在这项工作中，通过显微镜、马丁代尔耐磨性测试期间的电阻测量以及拉伸测试来评估它们的影响。研究阐明了纺织品上焊接导电轨道的耐用性和实用性。可以使用激光辐射将打成的铜连接到纺织品上，从而在 10,000 次磨损循环后显示出导电性。与混纺纺织品相比，完全由热塑性塑料制成的纺织品的拉伸强度受激光热输入的影响更大，但耐磨性较差。此外，还将展望使用波长为 450 nm 的激光源（蓝色激光）和扫描仪作为光学器件进行焊接的可能性。
