Design of closed fibers-converging device of swirl spinning

This paper introduced the swirl spinning process and the main components of machine,including combing roller,drafting device,fibers′ funneled transporting device,closed fibers-converging device and swirl twisting device.It discussed the design of closed fibers-converging device of swirl spinning which is the key part of swirl spinning,analyzing its feasibility from theoretical and experimental aspects.On this basis,some polyester/cotton core yarns were spun,the yarn′s structure was observed and its principle was analyzed.The experimental results revealed that this machine with closed fibers-converging device can produce yarn successfully.Its appearance is different from that of disc swirl spun yarn.
