Drawing and Roving
Six to eight slivers travel overhead and are then blended into one thick sliver. Cotton slivers must go through additional blending and combing processes. Finally, both cotton and polyester slivers undergo a drawing process to ensure fibers are uniform and parallel to each other. At this point slivers are reduced in thickness and given a slight twist in order to hold the weakened fibers together for spinning. These finer slivers are called rovings.
