摘　　要：为有效控制精梳纯毛纱的条干质量,通过推导与实验验证,导出了用于原料选配的羊毛直径计算式、毛纱理论条干变异系数计算式以及用于快速确定2种毛条配比的计算式。提出以条干品质指数为导向的前纺半制品条干质量控制流程,依据最新乌斯特统计公报对毛纱条干质量水平进行预测、分析。同时,借鉴国外先进经验,通过分析前纺半制品的条干质量分析曲线图对条干质量数据进行跟踪研究,为生产技术方案及时得到反馈、调整与优化提供依据。结果认为,以品质指数为导向的条干质量控制技术能更科学有效地实现精梳纯毛纱的质量目标。To effectively control the quality of combed pure wool yarn evenness,some theoretical equations were introduced in this article by theoretical calculation and experimental verification.These equations include calculation formula of raw material of wool diameter design value and theoretical sliver evenness coefficient of variation of wool yarn,and the calculation formula used to rapidly determine the ratio of two kinds of wool top through analysis.The semi-product evenness quality control process for forespinning based on quality index number is put forward according to the latest Uster statistical bulletin to forecast and analysis the quality level of the wool yarn evenness.At the same time,drawing lessons from foreign advanced experience,track and analysis on the quality data of the sliver evenness could be made through drawing the sliver evenness quality analyses graph for fore-spinning semi-products.This contributes to make the production technical schemes acquire timely feedback,adjustment and optimization.The results show that quality control technology guided by the sliver evenness quality index number can be more scientific and effective to achieve the quality objectives of the combed pure wool yarn.
