The technological potential of rotor spinning

Index

  • Rotor spinning is a stable spinning process, i.e. it functions trouble-free under normal spinning conditions, without variations in running behavior or yarn quality.
  • The process is reproducible with standard spinning equipment and settings and transferable to a large number of spinning positions. Quality consistency is therefore adequately assured both within the spinning positions of a machine or a group of machines and over an extended period of time.
  • Rotor spinning is a genuine open-end spinning process, i.e. a genuine twist is imparted to the yarn, making it comparable to ring-spun yarn in its yarn structure and as regards its applications (differences in principle from ring-spun yarn will be dealt with in more detail in subsequent chapters). From the outset rotor-spun yarns therefore had a wide range of applications instead of the ring-spun yarns used to date.
  • As a rule rotor spinning operates with normal drawframe sliver of a quality customary in spinning mills. Special preparatory passages, such as are sometimes necessary for other spinning processes (e.g. air-jet spinning), are not required here.
  • Rotor spinning is appropriate for mill operations in that its technology can be implemented with relatively simple and robust spinning elements.  
  • The process imposes no special requirements on the atmosphere in the spinning mill as regards temperature, humidity and air conditioning and in many cases is actually less critical in this respect that ring or air-jet spinning.
