The study of fly generation during weft knitting has attracted the attention of many workers for decades.Among all fiber properties, the fiber length has the greatest effect on the amount of fly generated during knitting. Blending with a synthetic fiber type also reduces the fly generation due to an increase in the fiber mean length. Additionally, yarn moisture content, stitch length, yarn speed and input tension, and package conicity have a significant effect on the fly generation. Although there is no listed literature for fly prediction techniques, fiber and yarn properties, along with knitting parameters, can be used for fiberfly prediction during knitting
