摘要：
The effect of yam Linear density, core content and friction ratio on radial packing density and mechanical properties of polyester DREF-3 yarns has been studied. It is observed that the packing density is maximum at the core and it decreases towards the surface. The packing density of a fine yam is less than that of a coarse yam, irrespective of the process parameters. The higher the care content and the friction ratio, the higher is the packing density. An increase in the core content and friction ratio results in large increase in tenacity, initial modulus, breaking extension, flexural rigidity and abrasion resistance of yams.
