摘要：为了控制精梳落棉率稳定，减少波动，从配棉中短绒百分含量变化、精梳前机台供应、精梳小卷成形质量及精梳机状态四个方面详细分析了精梳落棉率波动的原因；从原棉种类和储备，抓棉机工作参数，开、清、梳棉机开松和梳理元件的定期检查，优化条并卷机相关工艺参数、消除锡林嵌花等方面给出了减少精梳落棉率波动的措施。指出：配棉中短绒含量变化大、精梳前供应的机台不固定、精梳小卷成形质量差、精梳机状态不良均会造成精梳落棉率波动；应合理确定精梳落棉率，通过增加原棉储备，做好配棉，固定精梳前机台的供应，优化精梳机工艺及保证器材状态良好，优选精梳锡林齿条参数及组合等措施减少精梳落棉率波动；为了保持成纱质量的一致性，不应随意调整精梳落棉隔距。

Abstract:To keep stable noil rate of the combing frame,and to reduce the fluctuation,analysis is done to the noil rate fluctuation from four aspects including cotton linters percentage changes,frame supplies before combing,small bobbin forming of combed yarn and condition of the combing frame.Some measures are given to lessen the fluctuation of noil rate from the aspects including raw cotton varieties and the reserve of the same,the plucker working parameters, regular check-up and maintenance of the elements of the open-clear-card combination,optimiziation of the related process parameters,elimination of cotton jamming of the cylinder.It is pointed out that the noil rate fluctuation results from the change of short fibre content in cotton assorting,unfixed frame supplies before combing,poor small bobbin forming quality, poor condition of the combing frame.It is recommended that the comber noil rate be properly selected,the cotton reserves increased,a good job done in cotton assorting, fixed combing frame and supply,the process of combing frame and good condition of equipment optimized,proper combing cylinder rack parameters selected and combination of measures taken.Only by doing so,can noil rate fluctuations lessened.And more,in order to maintain the consistency of the yarn quality,voluntary adjustment of the comber noil gauge is not allowed.
