Abstract

In rotor spinning, it is generally regarded that the maximum fibre length (LFibre) should not exceed the rotor diameter (Drotor), and as such, their ratio (LFibre/Drotor) should lie between 0.5 and 1 for the proper processing and yarn formation to ensure production of an acceptable quality of the yarn. The present study examines the validity of the said guideline in terms of mean and peak yarn tensions generated during the spinning and their correspondence with the yarn quality. The study found that the optimum yarn quality can be produced, if LFibre/Drotor ≈ 0.8, at which the mean yarn tension maximizes and the peak yarn tension minimizes.
