梳针分梳板对棉结去除的影响

为研究梳针分梳板对棉结去除的影响,用AFIS单纤维测试仪对梳棉机刺辊下采用梳针分梳板、锯齿分梳板、小漏底在不同加工条件下所加工的生条进行棉结检测,结果显示:1)在隔距较小范围内,梳针分梳板去除棉结和SCN能力更强一些;2类分梳板去除棉结和带籽屑棉结(SCN)能力都比加小漏底方案要好。2)在隔距较大的条件下,锯齿分梳板去除棉结能力要强于梳针分梳板,分梳板去除棉结能力不如小漏底。分梳板和小漏底对SCN的去除随原料不同而有所差异。3)在小隔距条件下,锯齿分梳板所加工生条棉结直径稍大,在大隔距条件下,梳针分梳板所加工生条棉结直径稍大;和小漏底相比,分梳板所加工生条棉结直径略小。

Effect of pin carding plate on removal of neps

To research the effect of pin carding plate on removal of neps in the card slivers,nep tests to the card slivers under different processing conditions using pin carding plate,saw-tooth carding plate and taker-in grid under the card taker-in by USTER AFIS single fiber tester were done.The results show that: 1) within a smaller gauge range,the ability of removing neps and seed coat neps(SCN) of pin carding plate is stronger;the ability of removing neps and SCN of pin carding plate and saw-tooth carding plate are better than the taker-in grid program as a whole;2) when the gauge is larger,as a whole,the ability of removing neps of sawtooth carding plate are better than pin carding plate and that of the above two kinds of carding plate are worse than taker-in grid.The ability of removing SCN of carding plate and taker-in grid are different with the change of raw materials;3) when the gauge is smaller,neps diameter in the card slivers processed by saw-tooth carding plate is a bit larger.When the gauge is larger,neps diameter in the card slivers processed by pin carding plate is a bit larger.Compared with taker-in grid,neps diameter in the card slivers processed by carding plate is a bit smaller.
