| Abstract: | The effect of opening roller speed,
difference in drum speed and suction air pressure on packing density parameters
of open-end and core-sheath friction spun yarns has been analyzed using the
Box-Behnken method and response surface equations. The trends of change in
packing density with process variables are found to be opposite to those of
yarn diameter. Yarn diameter decreases, and helix angle and packing density
increase with the increase in suction air pressure for open-end and core-sheath
friction spun yarns. Core-sheath friction yarns have lower yarn diameter and
helix angle, but higher packing density than open-end friction yarns. |
