This method is called warp knitting, and the fabric is called warp knitted fabric. The machine that completes this warp knitting is called a warp knitting machine. The warp knitting machine mainly consists of a knitting mechanism, a comb bar traversing mechanism, a warp feeding mechanism, a pulling and winding mechanism, and a transmission mechanism. The knitting mechanism includes a needle bed, a comb bar, a sinker bed, and a pressure plate, which are generally driven by a cam or an eccentric connecting rod. Cams are commonly used in warp knitting machines with relatively low speeds and more complex movement laws of loop-forming parts. Eccentric connecting rods are widely used in high-speed warp knitting machines because of their stable transmission, relatively simple processing, less wear and noise during high-speed operation.
