梳棉机刺辊落棉和盖板花纤维长度分布

用罗拉式纤维长度测量仪对3种梳针刺辊和1种锯齿刺辊在二档道夫速度和四档刺辊速度的不同工艺条件下的刺辊落棉和盖板花纤维长度分布进行了检测。结果显示,1)刺辊落棉中13mm以下短纤维含量:锯齿刺辊在41.6%~50.51%之间,梳针刺辊在27.4%~43.48%之间,锯齿刺辊排除短纤维能力明显强于梳针刺辊,3种梳针刺辊中以工作角小的梳针Ⅰ型刺辊排除短纤维的能力较强;2)锯齿刺辊和工作角小的梳针刺辊对纤维损伤比较严重;3)盖板花中13 mm以下短纤维含量:锯齿刺辊在48.23%~54.6%之间,梳针刺辊在45.92%~58.23%之间。

Study on fiber length distribution of taker-in droppings and card strips

The fiber length distribution of taker-in droppings and card strips under such conditions as three kinds of pin taker-in and one kind of saw-tooth taker-in at speeds of two doffer and four taker-in level are tested with roller cotton fiber length analyzer.The results show that: 1)Fibers shorter than(13 mm) account for 41.6%～50.51% in saw-tooth taker-in droppings and 27.4%～43.48% in pin taker-in droppings.In the case of the ability of removing short fibers,the saw-tooth taker-in is better than the pin taker-in,and among the three kinds of pin taker-in,the one with small working angle is the best.2) The saw-tooth taker-in and the pin taker-in with small working angle lead to more serious damage to fibers.3)Fibers shorter than(13 mm) account for 48.23%～54.6% in saw-tooth taker-in card strips and 45.92%～58.23% in pin taker-in card strips.
