How is ring yarn different from rotor yarn?

Ring yarn and rotor yarn are two common types of yarn used in the textile industry. The main difference between them lies in the spinning process used to create them.
Ring yarn is made by using a spinning method that involves a ring spinning frame, winding it onto a bobbin. This process produces yarn that is strong, smooth, and has a consistent diameter.
On the other hand, rotor yarn, also known as open-end yarn, is made using an open-end spinning process. This involves feeding fibers into a rapidly spinning rotor, which pulls and twists the fibers into yarn. The yarn is then wrapped onto a bobbin. This process is faster than ring spinning, but the resulting yarn is coarser, weaker, and less even in diameter than ring-spun yarn.
Overall, ring-spun yarn is more expensive and of higher quality than rotor-spun yarn, making it a preferred choice for high-end textiles such as fine clothing, linens, and luxury bedding. However, rotor-spun yarn is often used for products that don’t require as much strength or consistency, such as t-shirts and towels.
