精梳机顶梳插入深度对精梳及成纱质量的影响

Influence of Top Comb Insertion Depth on Combing and Yarn Quality of Comber

分析了顶梳的结构组成及其工作原理,探讨顶梳插入深度对精梳及成纱质量的影响。结果表明:当顶梳插入深度为0时,精梳条及成纱条干CV值最小,成纱强力最高;当顶梳插入深度为+0.5时,精梳条中棉结、短纤维含量最低,纱线千米棉结、粗节及细节个数最少。

The composition and working principle of the top combing mechanism were analyzed.The effect of insertion depth of top comb on combing and yarn quality was discussed.The results showed that when the insertion depth of the top comb was 0,the CV value of combed sliver and yarn was the lowest,and the yarn strength was the highest;When the insertion depth of top comb was+ 0.5,the content of neps and staple fibers in combed sliver was the lowest,and the number of kilometer neps,slub and fine end of yarn was the lowest.
