What is ring spun carded and combed yarn and what are their uses?

There are three commercial methods of spinning yarn into the product we see at the store. They are called Ring Spun, Rotor Spun, and Friction Spun. Each method produces different results in the yarn.

The full question, ring spun carded and combed, refers to the fiber preparation method of carding (brushing) and combing the fibers prior to spinning, in order to form a softer yarn which is best for soft knit items. The fibers are spun in a ring arrangement making it unnecessary for extra plies, so the yarn is much finer.

There is also a downside to using ring spun, because the very process that causes it to be softer also causes the yarn to be more prone to breaking.
