摘要

Cotton bales are frequently intermingled with foreign fibers which will interfere in the process of spinning, weaving and dyeing and will worsen the product quality. Nowadays, cotton fibers are sorted manually in most of the cotton textile mills with very low efficiency. There is a great demand for foreign fiber detection devices in Chinese cotton textile mills. The air flow in the conveying pipe of the device has an important effect on the image acquisition, image analysis and removal of foreign fibers. As a primary effort, the air flow in the conveying pipe of the foreign fiber detection device was simulated numerically. The effects of the inlet air velocity on the air turbulence intensity and air velocity along the detecting section were studied.
