模糊综合评判棉纤维纺纱过程中的性能变化

应用模糊数学模型,采用原棉染色跟踪测试法,对纺纱加工过程中棉纤维长度、细度、成熟度、棉结以及断裂强伸度等物理指标进行二阶模糊综合评判,定量分析了各工序棉纤维综合性能的变化情况。评判结果表明:粗纱中棉纤维综合性能最好,梳棉生条中棉纤维的综合性能最差,细纱中棉纤维的综合性能仅好于生条中棉纤维的综合性能。由于二阶模糊理论的使用,使这一结果具有一定的可信度,从而为棉纤维的合理加工与使用提供了科学的依据。

Evaluating changes of cotton fiber performances in spinning using fuzzy math model

Using fuzzy math model and the dyed raw cotton testing,the changes of physical properties of cotton fibers in spinning such as length of fiber,fineness,maturity,neps,breaking strength,and elongation were evaluated by means of the two-grade fuzzy model. A quantitative analysis of these changes in individual process was conducted. The results indicate that with respect to the comprehensive performances of the cotton fiber,the roving exhibits the best,the sliver,the worst,and spun yarn better than the sliver only. These results provide a scientific basis for rational processing and application of cotton.
