摘　　要：通过实验和理论分析,根据四元件模型,研究了喷气涡流纺的松弛机理,并得出纱线松弛的本构方程。与环锭纺纱线相比,喷气涡流纺纱线的松弛时间更短,也就意味着纱线的应力释放更快,更容易达到稳定状态。In this artcle, based on the testing and the theory analysis, according to the four-element model, the relaxation mechanism if vortex spun yarn is studied, and the regression equation about yarn relaxation is concluded. Comparing with the ring spun yarn, the relaxation time of vortex spun yarn is shorter, which means the dropping of yarn stress is quicker and the yarn is easier to get to the new stable position.
