ABSTRACT

Cotton trash is known to affect textile-processing efficiency. Removal of cotton trash has often been a means to improve textile spinning. To combat trash and efficiency problems, Hamrick Mills (as do other textile mills) specifies cotton bales, which they acquire, should be no higher than a 3 leaf for processing on their Murata Airjet Spinner (MJS) or Murata Vortex Spinner (MVS). This leaf grade cut-off point is based on their past spinning experiences which point toward processing problems during weaving and excessive loom stops. This research determined how HVI Trashmeter software evaluates cotton trash and its particle size distribution in a 40-bale textile mill laydown. This study compared the distribution of particles within all bales and how similar these bales were to one another. The study further compared the change in trash particle distribution and HVI properties through the bales. Further work is needed to determine if leaf grade or trash particle distribution provide enough information for the measurement of cotton trash in high speed textile spinning.
