What is difference between ring spun, open end and Autocoro yarn

Ring spun yarn is a better quality yarn with higher prices and higher cost of production as compare to open end or Autocoro yarns.
Ring spun yarn factory consist of the following manufacturing processes.
1. Blow Room.
2. Carding.
3. Drawing.
4. Combers or Combing process.
5. Simplex
6. Ring
7. Winding or Auto cone department
Above is the complete spinning or yarn manufacturing process engage in the ring spun yarn production.

The open end or Autocoro is same till Drawing process but after that all work is done by rotor machine which decrease the production cost but at the same time as high draft is given so the quality of yarn suffered due to high draft. This factor also affects the quality of yarns. In ring we hae wide range of options for yarn counts but in open end or autocoro we can produce limited number of yarn counts.

Following processes are engaged in open end or autocoro yarn manufacturing.
1. Blow Room.
2. Carding.
3. Drawing
4. Rotor machines.

What is difference between Open End and Autocoro Yarns.

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.
