| Abstract: | Fibre
axial distribution of cotton ring - spun yarn using three process variables,
viz. card draft, coiler diameter of card and delivery speed of draw frame, has
been studied. It is observed that the percentage of trailing, leading and total
hooks and their extents on ring-spun
yarn decrease with the increase in draw frame delivery speed and coiler
diameter at carding machine. The above parameters also decrease as the card
draft increases. Since the fibre extent and spinning - in coefficient are
related to the efficacy of hook removal, these parameters improve as the
delivery speed and coiler diameter increase and deteriorate as the card draft
increases. It is also observed that the fibre overlap index decreases as the
delivery speed and coiler diameter increase; the parameters however increase
with the increase in card draft. It is interesting to note that the spinning-in
coefficient and fibre overlap index do not show positive relationship |
