Abstract: Disc swirl spinning was put forward as a new spinning method,which included combing roller drafting device,fibers'funneled transporting device, disc fibers-converging device and swirl twisting device.Disc swirl spinning process and mechanism design were introduced,and the yarn performance was elementarily tested and analyzed.The SEM photo of disc swirl spun yarn was compared with those of air-jet spun yarn and rotor spun yarn.It was found that the appearance of disc swirl yarn is similar with that of rotor yarn while the inner structure of the disc swirl yarn is similar with that of the air-jet yarn and the yarn is wound by true twist.The breaking strength of disc swirl core spun yarn is a little lower than that of the ring core spun yarn,while breaking elongation CV(%) is higher.The rest performances of the two yarn are similar.
