Open End Spinning
In the late 1960’s, a new spinning system was developed in Czechoslovakia. The principal behind open end, or rotor, spinning is similar to 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 around into yarn and comes out, wrapped up on a package, all ready to go to the next step. There is no roving stage or re-packaging (autoconer). This system is much faster, speeds up to 140,000 RPM, and more efficient. The most important fiber property in open end spinning is strength. West Texas cotton is not as long, but strong, so it goes into coarse counts of open end yarn. Denim, towels, sheets are made from our cotton *域名隐藏* /itc/images/ *域名隐藏* )
