The jacquard needle hooks the yarn of the weaving mechanism, and the tension of the yarn is controlled by the up and down movement of the jacquard needle. The jacquard pattern is formed when the yarn is looped by using the change in the tension of the yarn. For example, in the patent application with application publication number CN 102041632A and titled “A warp knitting machine capable of automatically removing cotton wool”, a warp knitting machine capable of automatically removing cotton wool is disclosed, which mainly includes a frame, a main shaft, a bottom comb main shaft, a needle bed, a comb bar, and a jacquard mechanism capable of weaving various shading jacquards, wherein the jacquard mechanism includes a faucet fixed on the frame, a rotating shaft, and a jacquard line. In the patent application with application number CN200520114702.9 and name “Multi-bar-belt Electronic Jacquard Warp Knitting Machine”, a multi-bar-belt electronic jacquard warp knitting machine is disclosed, including a multi-bar warp knitting mechanism mainly composed of a machine body, a hanger, a main shaft, a needle bed, a machine head and a comb bar; it also includes a jacquard jacquard mechanism capable of weaving various shading jacquards, the main components of which include a faucet, a rotating shaft, a jacquard needle and a jacquard thread; a main shaft pulley is installed on the main shaft to connect the belt through the rotating shaft and the faucet of the jacquard jacquard mechanism to drive them to operate synchronously through a transmission mechanism; a jacquard needle is installed on the faucet of the jacquard jacquard mechanism, and a jacquard thread is hung on the jacquard needle to connect the jacquard needle on the jacquard comb bar, and the jacquard needle controls the weft thread on the weft thread bar to weave various shading jacquards.
