Combining the triangular trajectory design, the angle of feeding yarn, the position and tension of the needle, and the needle with advanced hardness treatment, Bailong established the core technology of the Knitel series, and the trajectory of the needle and sinker was rigorously simulated and calculated by computer, and the results were obtained through repeated tests in the industry. The triangle manufacturing is precise, the surface is smooth, and all of them are fixed with a triangle seat slide, providing precise positioning, the weave mesh can present a better degree of uniformity and external leveling effect, and greatly improve the life of running consumables and parts.
