Pre-wound bobbins thread is high technical bobbin applied for multi head embroidery machine. It is 2 or 3 times longer than the normal thread, it can reduce the number of times of changing thread, hence it can also improve the output of production. The pre-wound bobbins thread is less 50% loss than traditional bobbins (because it won't brought waste if not used up). Owing to without bobbin, the head won't touch the bobbin when embroidery, which won't result in no point of needle and breaking of needle head, and reduce the rate of thread-cutting.
