Effects of Condenser Drum Covering at Cotton Gins on Card Room Dust and Quality of Yarn Produced by Open-End Spinning
ABSTRACT STUDIES were conducted to determine whether the wire mesh used on condenser drums at cotton gins in-creased the card room dust levels and had any adverse ef-fects on the quality of yarn produced by open end spin-ning. The investigation included five combinations of condenser drum coverings at two seed-cotton cleaning levels. Data collected indicate the card room dust levels were affected by the condenser drum coverings at the max-imum level of seed-cotton cleaning, but not at the minimum level. Data regarding the quality of yarn pro-duced by the open end spinning process indicated that none of the measured yarn-quality variables were adversely affected by condenser drum coverings when processing seed-cotton at the maximum seed-cotton cleaning level. Only the skein-break factor and the single-strand yarn strength were affected at the minimum seed-cotton cleaning level.
