拉舍尔提花经编针是用于多梳栉提花经编机的核心成圈机件，通常为舌针。其通过精准控制多把梳栉与贾卡装置的协同运动，将不同原料、颜色的纱线按设计要求进行垫纱，并由针舌的自动开闭完成成圈、衬纬或形成衬垫等结构，从而在织物中编织出复杂、多层的精致花纹图案，是生产高端蕾丝、网布及装饰织物的关键技术元件。

Raschel Jacquard Warp Knitting Needles are core loop-forming elements used in multi-bar jacquard warp knitting machines, typically latch needles. They enable the precise coordination of multiple guide bars and Jacquard devices to lay yarns of different materials and colors according to design requirements. The automatic opening and closing of the latch complete loop formation, weft insertion, or laying-in structures, thereby weaving intricate, multi-layered patterns into the fabric. These needles are key technical components for producing high-end lace, mesh, and decorative fabrics.
