经编槽针，又称复合针，是现代高速经编机的核心成圈机件。由带导槽的针身和可滑动的针芯精密配合，通过两者的相对运动完成垫纱、套圈和脱圈。此设计惯性小、运动平稳，是实现每分钟数千针超高速编织、提升效率与织物品质的关键。

Warp Knitting Compound Needles, also known as compound needles, are the core loop-forming elements of modern high-speed warp knitting machines. They consist of a grooved needle body and a sliding needle core that work in precise coordination. The relative motion between these two components completes the processes of yarn laying, loop casting, and knock-over. This design features low inertia and smooth movement, making it key to achieving ultra-high-speed knitting of several thousand cycles per minute, thereby enhancing efficiency and fabric quality.
