The problem of lint shedding has been widely recognized in the textile industry
for years. Fiber fly causes fabric defects and machine stoppages which result in
productivity losses and increased manufacturing costs. Consequently, minimization of
shedding is desired for maximization of. yarn performance.
In this research, increasing rotor speed was found to result in an increase in lint
shedding and lower quality for 50/50 polyester/cotton yarns. However, this research
points out that the effects of rotor speed can be minimized through the proper selection
of polyester fiber characteristics and spinning parameters. Specifically, the following
polyester fiber characteristics and machine components were found to allow for the
least lint shedding:
1. High molecular weight polyester fibers,
2. Coarser and longer fibers, .
3. Low levels of fiber finish (0.10% instead of 0.13% or treatment with an
overspray), and
4. Using a less aggressive KN4 navel instead of a KN8 navel.
