刺辊转速对生条中未成熟纤维去除的影响

为探讨刺辊转速对生条中未成熟纤维去除的影响,采用USTER AFIS单纤维测试仪对10档刺辊转速条件下所加工的生条进行了未成熟纤维含量的检测,结果显示:与棉卷相比,生条中未成熟纤维含量减少,纤维细度变粗,成熟度比变大;刺辊转速为800 r/min时,最有利于未成熟纤维的去除,刺辊转速为1 500 r/min时,最不利于未成熟纤维的去除;刺辊转速为1 300 r/min时,生条中纤维的细度最粗,刺辊转速为800 r/min时,生条中纤维的成熟度最大。

The effect of taker -in speed on the removal of immature fiber

To discuss the effect of taker-in speed on the removal of immature fiber,the immature fiber content in the card sliver processed under the conditions of ten-grade taker-in speeds was tested by USTER AFIS single fiber tester.The results show that(1)compared with lap,the immature fiber content in card sliver reduced,the fiber fineness became thicker and the maturity ratio became bigger;(2) it is most advantageous to removing immature fiber when the taker-in speed is at 800r/min and it is disadvantageous to removing immature fiber when the taker-in speed is at 1500r/min;(3) the fiber fineness in the card sliver is thickest when the taker-in speed is at 1300r/min and the maturity ratio in the card sliver is biggest when the taker-in speed is at 800r/min.
