Removal of cotton fibers from cottonseed during the ginning process requires substantial quantities of electrical energy. The strength of attachment must be overcome by the mechanical force applied to separate the fibers from the cottonseed. Fiber breakage of seed-coat ruptures can occur when excessive force is required to remove the fiber. Studies of 20 varieties planted on two dates in two states show that the electrical energy required for fiber/seed separation ranged from 16.2 to 23.2 watt-hours per pound of lint. Some correlation was evident between seed-coat fragment weight, short fiber content, and electrical energy.
