RING & ROTOR SPINNING DIFFERENCE
RING & ROTOR SPINNING
Today I am going to discuss Ring spinning & Rotor spinning.
Ring yarn is generally produced from the long fibers of cotton. Ring yarn is divided into 2 types 1. carded and 2. combed cotton. MAIN DIFFERENCE The main difference between Combed & Carded yarns is the combing process. Combed yarn is produced by a combing process. Carded yarn is made without a combing process. COMBING PROCESS : The combing process of cotton feeds the machine with the help of the combs in the machine, and thus the short fibers of the cotton are separated. Depending on the cotton used and the machine settings, 5-25% fiber can be extracted from the raw material and evaluated for different quality. ROTOR SPINNING : This is not the same as ring spinning. This is also known as Open-end yarn. The rotor spinning system is a completely different production technique compared to ring yarn. It is produced from cotton’s short fibers. A rotor rotating at a very high speed is fed with the cotton roving prepared using short fibers. Due to the centrifugal force, the wick spreads and adheres to the rotor surface. Open-end yarn is produced by continuously pulling a yarn extended into the rotor. RING & ROTOR DIFFERENCE: 1-The production speed in Rotor spinning is higher than in Ring. This is a factor that increases production while decreasing the cost. 2- The process steps of Rotor spinning are shorter than Ring spinning. So Rotor spinning cost is less than ring yarn. 3-Rotor is bulkier, more elastic, more absorbent, and less hairy than Ring yarn. If the twist is not very high, the attitude is also good. Its good absorbency provides high sizing percentage and brighter shades. 4-The properties of the yarn produced in the Open-End system are less variable than the ring yarn. Thinness, unevenness, durability, etc. changes less along the thread. The finer count can not be possible to knit in Rotor spinning but we can make a finer count in Ring spinning.
