Spinning is a process where yarn makes from cotton or something else by twisting though spinning frame machine. There are a few types of spinning machine are used around the world but we will discuss about most used machine like rotor spinning frame and ring spinning frame. Every modern machine has history which created by conventional machine. Modern machine is an upgrade version of conventional machine. Remove some unusual parts of machine & using some latest mechanical or electrical technology; speed up the machine and finally got the modern machine.

Ring spinning frame

Rotor spinning frame

No	Rotor Spinning frame	No	Ring Spinning frame
01	Rotor spinning frame is modern spinning system machine	01	Ring spinning frame is conventional spinning system machine
02	This machine makes yarn by high drafting from sliver.	02	This machine makes yarn by lower pressure than rotor spinning frame from roving.
03	The working speed of rotor spinning frame is faster than ring spinning frame.	03	The working speed of ring spinning frame is lower than ring spinning frame.
04	Usually rotor spinning frame produced lower count yarn.	04	This machine can produce from low count yarn to high count yarn.
05	Basically the raw material of this machine is low quality. Means low grade cotton.	05	Relatively this machine used high grade cotton to produce yarn.
06	Temperature and moisture of cotton should be controlled to produce yarn by rotor spinning frame.	06	No need to control temperature and moisture of cotton to produced yarn by ring spinning frame.
07	Room temperature should be controlled in 20 to 28 C on spinning room.	07	Its better if the room temperature controlled in 28 to 35 C.
08	Only one drafting system is available on this machine so there are now break draft in this machine.	08	Darting system is split in two divisions called main draft and break draft.
09	Twisting and winding process work separately in rotor spinning frame.	09	Twisting and winding process work with each other.
10	Production of rotor spinning frame is more than ring spinning frame.	10	Production of ring spinning frame is less than rotor spinning frame
11	Consumption of electricity is less than ring spinning frame.	11	Consumption of electricity is more than rotor spinning frame.
12	The ratio of breakage yarn is less than ring spinning frame.	12	The ratio of breakage yarn more than rotor spinning frame.
13	Production sound or noise is less than ring spinning frame.	13	Production sound or noise of the machine is more than ring rotor spinning frame.
14	The produced yarn package large.	14	The produced yarn package is small.
15	A few labor or technician can produce or maintain rotor spinning machine.	15	Ring spinning machine required more than ring spinning frame machine.
16	Rotor spinning frame produced balanced yarn.	16	Ring spinning frame produced less balanced yarn.
17	Trash less cotton is perfect for make yarn balanced so always used cotton should less trash cotton.	17	Comparability this machine can produce yarn from maximum amount of trash full cotton.
