In wrap spinning, a bundle of parallel fibers is wrapped in a spiraling fashion with other fibers. A bundle may contain 150-200 individual fibers along its length, yet not be thicker than a paper clip.
Yarns spun by other methods are similar in size.
Warp spinning is suitable for making strong, dense yarns. In ring spinning a parallel bundle of fibers is tightly twisted for cohesion and strength. No wrapper fiber is needed. With open end spinning the yarn has individual fibers that are not arranged as uniformly as in wrap or ring spun yarns. Most of the fibers are generally parallel, but with lots of crisscrossing, while some fiber irregularly wraps around the main bundle.
