摘　　要：研究收集了41种唛头的棉纤维样本,利用HVI测试样本的长度、马克隆值、长度整齐度、断裂比强度、轧工质量和颜色级6项性能指标,通过小样试纺在同样的工艺设置下纺成32支坯布用纱,并检测成纱条干及毛羽质量。采用趋势分析法探究单一棉纤维性能对成纱质量的影响关系并筛选出影响显著的指标,接着利用选出的棉纤维性能指标使用灰色关联法构建其对成纱条干和毛羽的影响权重测算模型。研究表明对成纱条干影响最大的是长度整齐度,占比22.38%;对成纱毛羽影响最大的也是长度整齐度,占比23.24%。Cotton fiber samples of 41 markers were collected,and six performance indexes,namely,length,micronaire value,length uniformity,breaking strength,ginning quality and color grade,were tested by high volume instrument"HVI".These fibers were spun into 32Sgrey fabric yarns under the same process settings and test the yarnevenness and hairiness quality.Trend analysis was used to investigate the relationship between the performance of cotton fiber and the quality of the yarn,and screen out the indicators with significant influence.The selected cotton fiber performance indicators were used to construct the weighting model of their influence on yarn evenness and hairiness using the grey correlation method.The analysis shows that the greatest influence on yarn evenness is length uniformity,accounting for 22.38%,and the greatest influence on yarn hairiness is also length neatness,accounting for 23.24%.
