The cohesion or drafting force of cotton card sliver was enhanced by corona-discharge treatments. The level of treatment increased with the power in the corona, the number of corona zones, the number of passes through the corona apparatus, and the temperature of the cotton, but decreased with the moisture content of the cotton. Four different gases used in the corona reactor produced the same increase in sliver cohesion.
