| Abstract: | A newly developed methodology based on image
analysis technique has been used to measure fibre openness and the results are
compared with those of the traditional method of measurement of fibre openness.
The role of different opening process parameters in deciding the openness of
fibres has been examined and the effect of fibre openness on the quality of
fibres, slivers and yarns discussed. The openness of fibres obtained by image
analysis technique is found to be much higher than that obtained by beaker test
method. It is found that the higher speed of opening rollers and higher angle
of grid bars improve fibre openness appreciably, but with little deterioration
in fibre quality. The higher fibre openness ultimately results into more
regular and less imperfect yarn. With the increase in fibre openness, yarn
strength and yarn breaking elongation increase initially and then decrease. Yarn
hairiness remains almost unchanged with the increase in fibre openness. |
