This paper mainly introduces online digital image recognition and removal device of foreign fibers in opening and scutching machines.

介绍了开清棉机上采用的异性纤维在线数字图像识别和去除装置，比较了不同装置、不同位置时异性纤维自动检测清除系统的特点，提出了检测清除系统的去除条件与表征指标。

The preceding process of the machine is comblined opening and scutching machine and the follwing process is drawing frame.

本机的前道工序是开清棉联合机，后道工序是并条机，主要用于加工棉纤维和化学纤维。

The spinning process includes also scutching step with lap ration of

所述纺纱工艺还包括有清棉工序，该清棉工序的棉卷定量为600G/m～

It is believed that if nep number increases during scutching process, the taker-in plays a more active role in eliminating the neps while the stationary flat and web purifier do not.

研究认为：清棉过程中棉结数量增加，刺辊对棉结的去除作用很大，后罩板处加固定盖板和棉网清洁器的作用则不大。

By variance analysising, we find that opening and cleaning process has a great effect on neps and trash of card sliver, and that carding process has a great effect on short fiber content of card sliver.
