What is "Open End Spinning" - Definition & Explanation

A spinning system in which sliver feedstock is highly drafted and thus creates an open end or break in the fibre flow. The fibres are subsequently assembled on the end of a rotating yarn and twisted in. Techniques for collecting and twisting the fibres into a yarn include rotor spinning and frictionspinning.
The production of spun yarns by a process in which the sliver (q.v.) or roving (q.v.) is opened or separated into its individual fibres or tufts and is subsequently reassembled in the spinning element into a yarn.
System of spinning based on putting twist into the yarn without turning the bobbin. This is done by rotating the yarn end at a gap or break in the flow of fibers between the delivery system and the yarn take-up (bobbin). Open end spinning is usually not as smooth and soft as ring spinning.
The production of spun yarns by a process in which the sliver (q.v.) or roving (q.v.) is opened or separated into its individual fibres or tufts and is subsequently reassembled in the spinning element into a yarn. (See also spinning).
A Spinning System In Which Sliver Feedstock Is Highly Drafted, Ideally To Individual Fibre State, And Thus Creates An Open End Or Break In The Fibre Flow. The Fibres Are Subsequently Assembled On The End Of A Rotating Yarn And Twisted In. Various Techniques Are Available For Collecting And Twisting The Fibres Into A Yarn, The Most Noteworthy Being Rotor Spinning And Friction Spinning.
