精梳机顶梳工艺参数对梳理效果的影响
|
摘要
文章探讨了精梳机顶梳齿密及插入棉丛深度对梳理效果的影响,设计了26、28、30、32齿/cm共4种规格的顶梳齿密度,顶梳插入棉丛的深度采用"-0.5""0""+0.5"3种工艺,进行交互纺纱试验。结果表明:在顶梳插入棉丛的深度较小时,增大顶梳的齿密度有利于排除精梳条中的短绒及棉结,对成纱质量没有显著影响;增大顶梳的插入深度会使成纱千米棉结数减少、精梳落棉率增加;在顶梳插入深度由"-0.5"向"0"增大时,有利于改善成纱的IPI值,但成纱强力降低;在纺细绒棉产品时,顶梳的齿密度为26针/cm时成纱的综合质量为最优。
In order to investigate the influence of the top comb tooth density and the insertion depth on the combing effect, the paper carried out an interactive spinning test via designing four specifications of top comb tooth density, i.e., 26, 28, 30, 32 teeth/cm, as well as three technological parameters, i.e., "-0.5", "0","+0.5", to achieve different top comb insertion depth. Results indicated that increasing the tooth density of the top comb when the insertion depth of the top comb is small is beneficial to eliminate the short fiber and neps in combing sliver, but it has no significant effect on the yarn quality; increasing the top comb insertion depth will reduce the number of neps in the yarn and increase the noil percentage of combing; when the top comb insertion depth increases from "-0.5" to "0", the IPI value of yarn is improved, however, the yarn strength decreases; the overall quality of the yarn is optimal when the tooth density of the top comb is 26 teeth/cm in the fine cotton combing.
