Effect of twisting degree on yarn diameter and density

The degree of twisting of the spinning yarn not only affects the appearance quality such as diameter and finish of the spinning yarn, but also affects the intrinsic quality and feel of the spinning yarn such as strength, elasticity, elongation and so on. Therefore, the determination of the twist degree of spinning yarn in fabric technology is also particularly important. (1) Effect on the diameter and density of spinning yarn Twisting makes the fibers in the single yarn denser, the gaps between the fibers reduced, the density of the single yarn increases, and the diameter decreases. When the twist coefficient increases to a certain value, the compressibility between fibers in a single yarn becomes very small, and the density does not change much as the twist coefficient increases. On the contrary, the diameter of the yarn may increase slightly because the fibers are too tilted. The diameter and density of the strands are also related to the twist direction of the strands and single yarns. When the twist direction of the strands is the same as that of the single yarn, the relationship between the twist coefficient, density and diameter is similar to that of the single yarn. When the strands and single yarns are twisted in opposite directions and the twist coefficient of the strands is small, the density of the strands will decrease and the diameter will increase due to the untwisting effect of the single yarn; when the twist coefficient reaches a certain value, the The density of the strands increases with the increase of the twist coefficient, while the diameter decreases with the increase of the twist coefficient. As the twisting continues, the density does not change much, while the diameter gradually increases.
