摘　　要：为提高毛纱质量与毛纺工艺设计效率,通过理论推导与实验验证,建立毛纱捻缩率的预测模型。在截取毛纱横截面几何模型的基础上,逐步导出捻缩率与相关因素之间的数学关系。结果表明,根据所纺毛纱的线密度、捻度要求以及所用原料的平均直径与平均体积密度,利用毛纱捻缩率预测模型可以快速地获得捻缩率预测值;将捻缩率预测值用于计算细纱机前罗拉出条定量、选配捻度变换齿轮组时,毛纱的线密度偏差率与捻度偏差率可被有效地控制在FZ/T 22001—2010《精梳机织毛纱》中优等品毛纱所规定的范围内。In order to improve the precision of wool yarn specifications and the design efficiency of wool spinning technology,a wool yarn twist shrinkage prediction model was established by theoretical deduce and experimental reasoning. Based on the geometry model of wool yarn cross-section,mathematical equations among twist shrinkage and relative factors were deduced step by step. The results show that wool yarn twist shrinkage prediction value can be easily obtained by providing some factors such as wool yarn linear density,yarn twist,fiber mean diameter and fiber mean specific density. When the predicted shrinkage value is used in calculation of yarn linear density and in selection and combination of twist gears,the deviation ratios of wool yarn linear density and twist were within the prescriptive scope of ＂ FZ / T 22001—2010 Worsted Woven Wool Yarn＂.
