At the heart of the modern sewing machine lies the chain stitch mechanism. This technology uses a series of interlocking loops created by a needle and a looper. The chain stitch is distinctive due to its ability to create a durable seam that is both flexible and elastic. Unlike traditional lockstitches, which require two threads to form a cohesive seam, chain stitches use only one thread in a loop, significantly reducing the amount of material needed. This not only lowers costs but also accelerates the sewing process, enabling manufacturers to produce garments at a remarkable speed.
