Abstract:

In order to improve the moisture conductivities of compact-siro spinning pure polyester yarn, moisture conductivities of compact-siro spun yarn, siro spun yarn and compact spun yarn were analyzed and compared. Three kinds of linear density (14.6tex, 9.7tex and 7.3tex) of siro spun, compact spun, compact-siro spun pure polyester yarn with the same yarn parameters setting were spun, and the moisture conductivity was tested by capillary wicking. The results show that the compact-siro spun yarn obtain the optimum moisture conductivity compared with the other two kinds of yarn with different yarn has smoother surface, the least yarn hairiness, and the best yarn evenness. The cross-sectional shape of compact-siro spun yarn is closer to a circle and fibers of yarn body are twisted tightly, so the yarn structure is more closely. Therefore, the moisture conductivity of compact-siro spinning pure polyester yarn is excellent because of its special yarn structure, which offers possibility to improve the moisture conductivity of polyester fabrics.
