不同锯片数轧花机加工所得棉纤维性能对比

Comparison of the fiber properties which processing by ginning machines with different number of saw blades

为提高机采棉纤维质量,不仅需要优化棉花的种植采摘方式,而且需要合理配置机采棉的轧花加工机械,通过对比分析2种不同锯片数的轧花机械对棉花品质的影响,筛选适合加工机采棉的轧花机械。使用HVI测试经过不同轧花机械加工所得棉花的主要性能指标,利用MINITAB软件进行统计分析,得出2种轧花机加工所得纤维的各项指标差异,通过对比研究可知,少片数型锯齿轧花机加工所得棉纤维在长度、强度、杂质及叶屑等级指标中都优于多片数型锯齿轧花机。

In order to improve the quality of machine-picked cotton fiber,not only the planting picking method needs to be optimized,but also the ginning machine with cotton pick-up machine needs to be properly configured.By comparing and analyzing the influence of two kinds of ginning machines with different number of saw blades on the quality of cotton,the cotton ginning machine suitable for processing cotton was selected.The main performance indexes of cotton were tested by HVI instrument,the data were analyzed by MINITAB software,and the fiber property indexes of cotton processed by the two kinds of ginning machine were obtained,and the properties of the fiber produced by the less number of saw blades ginning machine was better than that of multi-chip saw blades ginning machine in the length, strength,impurities and leaf grade indicators.
