Abstract
According to the yarn mechanism of self-twist jet vortex spinning, this article analyzes the structure and the fracture mechanism of self-twist jet vortex spinning yarn. Combined with experiments, this article established that the fiber in self-twist jet vortex spun yarn has self-twist, which increases the mutual contact area and the cohesion between the fibers in the yarn. This is helpful to improve the evenness and tensile properties of jet vortex spun yarn. The self-twist jet vortex spinning can keep the high spinning speed of the jet vortex spinning at the same time. The research on self-twist jet vortex spinning lays the foundation for the research and the development of jet vortex spinning.
