Abstract:

In order to investigate the effect of winding and twisting on the mechanical properties of the air-jet vortex spun yarns, the deformation and force loading of the fibers in air-jet vortex spun yarn during stretching process was analyzed theoretically in this paper, and the effect of the vortex pressure and the spinning speed on the mechanical properties of the vortex spun yarn was investigated in detail. The results indicate that the spiral wrapping of the outer fibers play a decisive role in the mechanical properties of the yarn. The vortex pressure and the spinning speed are the two main factors affecting wrapping and twisting effect of the vortex spinning. When the spinning speed was fixed as 280 m/min, the breaking tenacity and the initial modulus of the yarn demonstrate an increase followed by a decrease, with the breaking elongation virtually unchanged, with the increase of the vortex pressure. When the spinning speed was fixed as 280 m/min with the vortex pressure being 0.55 MPa, the optimum mechanical properties of the yarn were obtained. When the vortex pressure was fixed as 0.45 MPa, with the increase of the spinning speed, the breaking tenacity and the breaking elongation of the yarn both show a slight decreasing trend, and the initial modulus shows a decrease and then stabilized.

Key words: vortex spun yarn, wrapping and twisting, vortex pressure, spinning speed, mechanical properties
