There is no major difference between open end and autocoro yarns. The simple difference is that auto coro yarn is produced on latest machines with same manufacturing system while open end yarn is produced on old open-end machines.
Open End machine is the older version of machines. It can mostly not produce finer or higher number of counts above 20/1 oe although We can produce up to 30/1 on open end machines but we have to decrease the machine speed which decrease the production and increase the production cost. Mostly coarser counts from 6/1 oe to 16/1 oe or 20/1 oe is produced on it.
Auto Coro is the latest machine having the ability to produce yarns of fine quality with higher speed. its count range is also higher and its drafting system allow you to produce yarn counts up to 60/1 although mainly people prefer to produce yarn counts till 40/1. Autocoro production capacity is also very high as compare with open end machine.
