摘要

Pure cotton low-twist single yarn has good softness, bulkiness, and wearing comfort, but its lower strength makes the yarn break easily during the spinning process, which seriously affects the spinning effect and progress. The addition of long-staple cotton helps to increase the average length and uniformity of the raw fiber, thereby improving the breaking load and spinnability of pure cotton low-twist single yarn. In this study, the addition of long-staple cotton, the twist factor, and the twist direction were used as variables to spin 22 kinds of combed 14. 6 tex pure cotton low-twist single yarn with spinnability, and the breaking load, the hairiness, and the unevenness of the yarn were tested. The result shows that the spinnability of pure cotton low-twist single yarn is mainly related to the breaking load, and with the increase of the twist factor, the breaking load of low-twist single yarn shows an obvious upward trend. When the proportion of long-staple cotton is 70％, the breaking load of low-twist single yarn is the largest, and the harmful hairiness index and unevenness of the yarn are significantly improved.
