摘要
采用逐步回归分析等方法对纺纱试验结果进行分析。结果表明,原棉的品质、纺纱工艺、纱线线密度均对纱线强力有影响,但原棉性质是决定纱线强力的主要因素;纤维长度、纤维强度、长度整齐度和马克隆尼值是表示棉花纤维综合品质的关键指标。基于上述研究结果,建立了普梳和精梳工艺下的单纱强力模型。模型为非线性模型,模型的机理性强,自变量少,形式简单直观,易于推广使用,具有较好的预测效果。
Stepwise regression analysis was used to study the experimental data of yarn spinning, and the results showed that the strength of yarns depends on the quality of cotton fiber, spinning technology and linear density of yarn; the pivotal indexes expressing the cotton fiber quality are cotton fiber length, strength, Micronaire and uniformity. The model of single yarn strength manufacture by combing or carding processes is established according to the findings above, which is a non-linear model having explicit mechanism, few independent variables, and good projecting validity. It is simple and intuitionist, and easy to promote for application.
