An adhesive-aided ring spinning was developed to improve cotton yarn quality through the wetting and adhesion effect of an adhesive solution, namely, sodium carboxymethyl cellulose solution on fibrous strand in yarn formation zone during spinning process. The spinning mechanism of the adhesive-aided ring spinning with sodium carboxymethyl cellulose solution was analyzed, and the effects of two factors, that is, speed ratio (the ratio of the linear surface velocity to the output speed) and sodium carboxymethyl cellulose concentration, on the yarn performance are investigated. The experiment results reveal that the adhesive-aided ring spinning with sodium carboxymethyl cellulose concentration of 0.7% can significantly reduce yarn hairiness indicated by the hairiness S3 value reducing to 69% and still showing a prominent reduction (65%) after winding process. It has been found that a slightly faster linear surface velocity of the cylinder of the adhesive-aided ring spinning compared with the output speed of the yarn is more beneficial to the reduction of yarn hairiness S1+2 value. Meanwhile, the higher sodium carboxymethyl cellulose concentration also contributes to a higher breaking strength (increasing from 18.24 to 21.12 cN/tex) and lower breaking elongation (reducing from 4.98% to 4.08%). The abrasion resistance of adhesive-aided ring spun yarns also shows an obvious improvement of 12.8%. Therefore, the newly developed adhesive-aided ring spinning with the sodium carboxymethyl cellulose solution provides an effective method to enhance the quality of cotton yarns.

羧甲基纤维素钠溶液助粘剂环锭纺提高棉纱品质

开发了一种粘合剂辅助环锭纺纱，通过在纺纱过程中在纱线形成区的纤维束上使用粘合剂溶液，即羧甲基纤维素钠溶液的润湿和粘合作用来改善棉纱质量。分析了羧甲基纤维素钠溶液助粘环锭纺的纺丝机理，分析了速比（线面速度与输出速度之比）和羧甲基纤维素钠浓度两个因素对纺丝效果的影响。研究了纱线性能。实验结果表明，羧甲基纤维素钠浓度为0. 7%可显着降低纱线毛羽，毛羽S3值降低至69%，并在卷绕过程后仍显示显着降低（65%）。研究发现，与纱线输出速度相比，助粘环锭细纱机筒体的表面线速度稍快，更有利于降低纱线毛羽S1+2值。同时，较高的羧甲基纤维素钠浓度也有助于较高的断裂强度（从 18.24 增加到 21.12 cN/tex）和较低的断裂伸长率（从 4.98% 减少到 4.08%）。助粘环锭纱的耐磨性也明显提高了12.8%。所以，
