Abstract

In this study, many approaches were examined such as spindle defects and yam bobbin position along with successively varying spindle speed to select the optimum processing parameters for standard testing of the Egyptian cotton, and hence suggesting a spinning procedure for the CRI 96-spindle-hour spinning test. Giza 80 was used to test the spindle error and yam bobbin position also, to study the varying spindle speed, while, Giza 80 as well as Giza 86 and Giza 70 were used to reveal the spinning limit technique. The coefficient of variation in lea count strength product (introduced between the spindles of the ring frame) was considerable, the variance was very small (1.01 %) in extreme cases and could be neglected. The lea count strength product at different positions on the bobbin spun on the ring frame between the pigtail to full bobbin was insignificant. The increase in spindle speed from 1000 to 17500 rpm did not affect single yam strength, yam evenness and yam hairiness. The total imperfections are minimum at 10000 rpm of spindle, and beyond this speed the imperfections increase gradually with the increase in spindle speed. The proposed procedure of accelerated spinning technique appears promising in indicating the relative level of end breakage and optimum yam quality parameters for different cotton varieties. A series of 96- spindle-hour spinning tests proved to be reliable in exploring practical spinning limits of any cotton to find out the finest count for a particular cotton taking in consideration ends-down and yam quality parameters.
