Worsted and woollen spinning

This course takes an in-depth look at the worsted and woollen spinning and post-spinning operations. It reviews the worsted and woollen production systems before covering the preparation of top for worsted spinning, worsted ring spinning and variations and alternatives for worsted ring spinning.

It then explores preparation for woollen spinning, woollen spinning and post-spinning operations.

The course is completed with a discussion of quality assurance in both worsted and woollen spinning operations.

By the end of this course, you should be able to:

  • describe the operations required to prepare top for spinning. Including finisher gilling and roving
  • describe the aims of spinning and the operation of the ring spinning frame
  • outline alternative spinning technologies that can be used for worsted spinning of wool
  • describe the operation of a woollen card and the preparation of the slubbing for spinning
  • understand the key limitations and relevance of factors influencing the operation of the spinning machine
  • describe post-spinning operations
  • outline the role of and techniques in quality assurance programs for woollen and worsted spinning and post-spinning operations.
