Open-end yarns are made using a spinning process called open-end spinning. It is also known as the carded, break or rotor spinning method. In this spinning process, the roving process is omitted, that is, the silver is directly fed into the rotary heater after the drafting process.

In this process, the silver is fed directly into the machine and then combed. After this, the fibers are deposited on the rotor and then along the trough with the help of airflow and centrifugal force. After this, the fibers are twisted from the yarn and then pulled out from the center of the rotor.

In this type of spinning method, there is no need to introduce twist into the yarn. This not only enables higher torsional speeds, but also reduces the cost of the power required. Therefore, the productivity of open-end spinning is about 6-8 times more that of the ring frame spinning method.

The yarn produced by open-end spinning process has uniform structure, low strength and good wear resistance. They have greater scalability, volume and water absorption.
