Purpose

This study aims to investigate the effect of process parameters of blow room machines on openness degree and quality of cotton tufts in a blow room.

Design/methodology/approach

For this purpose, an experimental Box–Behnken design (BBD) was used, and the process parameters were the angles of the grid bars underneath the opening rollers of CVT3 beaters and the distance between feed roller of the first opening roller of CVT3.

Findings

It was found that the cotton tuft openness increased by increasing the angles of grid bars and by decreasing the distance between the feed roller and first opening roller on CVT3 beater. Further, the optimization procedure showed that an optimum value of cotton tuft openness (in laser method) was determined for specific levels of the process parameters.

Originality/value

The originality of this investigation is that it showed the individual effects and interactions of the most important factors in two tufting machines instead of only one machine. This study is important because it helps cotton yarn spinners to improve the quality of the final yarns by optimizing the levels of tuft openness which in turn improves fiber cleaning.

基于Box–Behnken设计的棉簇开度响应面优化

目的

这项研究的目的是调查吹气机的工艺参数对吹气机中棉簇的开放度和质量的影响。

设计/方法/方法

为此，使用了实验性的Box–Behnken设计（BBD），其工艺参数为CVT3打浆机张纸辊下方的栅栏角度和CVT3的第一个张纸辊进纸辊之间的距离。

发现

已发现，通过增加格栅杆的角度并通过减小CVT3打浆机上的进料辊和第一个开松辊之间的距离，可以增加棉簇的开松度。此外，优化程序表明，对于特定水平的工艺参数，确定了棉簇开放度的最佳值（采用激光方法）。

创意/价值

这项研究的独创性在于，它显示了两台簇绒机而不是一台簇绒机中最重要因素的个体影响和相互作用。这项研究很重要，因为它可以通过优化簇绒开放度来帮助棉纱纺纱厂提高最终纱线的质量，从而改善纤维的清洁度。
