The problem of dust and fly

Index

Many short fibers are lost as fly during the processing of staple fibers on spinning machines, and a considerable quantity of fiber debris and dust is released. Fly and dust are deposited on machine components or are continuously being whipped up and around by rotating and circulating devices such as  spindles, drums, drive wheels, etc. They have therefore always been a significant disturbing factor as regards service and maintenance as well as diminishing quality. This problem has intensified further with high production speeds and high drafts. The most fly and dust on ring spinning machines is released in the main drafting zone and the spinning triangle (up to 85%), while the balloon and travelers account for most of the remainder. Since it is impossible to prevent fly from being released, provision should at least be made for removing it. Whereas this always used to entail manual cleaning of the machine components, blower devices are mostly used for this nowadays. However, it has to be said that blower devices do not function ideally, since they blow fly and dust off the machine components rather than removing them at the place where they occur, and therefore also whirl them over the machines. The accumulations of dust and fly therefore do not always end up where one would like them to. They can thus again result in disturbances. However, no better solutions are known at present.
