Effect of Sliver Preparation on Fibre Disorder at Rotor Groove.

By:- S.M.Ishtiaque & Ajay Saxena

  • On the basis of studies carried out , the following conclusions can be drawn :-.
    • 1.Fibre orientation at rotor groove is inferior to those in the feed sliver.
    • 2.Proportion of the curved ends in the corresponding sliver & rotor groove ring decreases , while the coefficient of relative fibre parallelisation increases , with the increase of drawframe passages.
    • 3. Mean fibre length at rotor groove increases with the increase of drawframe passages.
    • 4. Better fibre straightening , but not much improvement in fibre parallelisation is achieved with the second drawframe passage.
    • 5. Yarn tenacity increase with the introduction of the drawframe passages.
