Study on fibre openness - Its impact on roving drafting force and yam quality

Abstract

26-31A detailed analysis on the effect of fibre-to-fibre friction along with the carding parameters on the openness of fibre has been carried out. The fibre openness has been correlated with the drafting force of rovings and properties of sliver, roving and yarn. It is observed that the fibre-to-fibre friction has significant influence on the fibre openness. The increase in fibre openness results in decrease in roving drafting force. The nep count and short fibre content of card sliver, mass irregularity of card sliver, draw frame sliver, roving and yarn, total imperfections and yarn tenacity are significantly influenced by the fibre openness
