It was invented and developed in Czechoslovakia in Výzkumný ústav bavlnářský / Cotton Research Institute in Ústí nad Orlicí in 1963.〔Carl A Lawrence (2010) ''Advances in Yarn Spinning Technology'' pp. 261–273, Woodhead Publishing, Oxford ISBN 978-1-84569-444-9〕〔Zdeněk Pospíšil (1981) ''Příručka textilního odborníka'' pp. 411–425, SNTL, Prague (Czech)〕 ==Method== It is also known as break spinning or rotor spinning. The principle behind open-end spinning is similar to that of a clothes dryer spinning full of sheets. If you could open the door and pull out a sheet, it would spin together as you pulled it out. Sliver from the card goes into the rotor, is spun into yarn and comes out, wrapped up on a bobbin, all ready to go to the next step. There is no roving stage or re-packaging on an auto-coner. This system is much less labour-intensive and faster than ring spinning with rotor speeds up to 140,000 rpm. The Rotor design is the key to the operation of the open-ended spinners. Each type of fibre may require a different rotor design for optimal product quality and processing speed. The first open-end machines in the United Kingdom were placed, under great secrecy, by Courtaulds into Maple Mill, Oldham in 1967. One disadvantage of open-end spinning is that it is limited to coarser counts, another is the structure of the yarn itself with fibres less in parallel compared to ring-spun yarns, for example, consequently cloth made from open-end yarn has a "fuzzier" feel and poorer wear resistance. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Open-end spinning」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
