Process Flow Chart of Rotor Yarn Manufacturing | Cotton Fiber to Yarn Manufacturing

Rotor spinning process is fully different from carded or combed spinning. Rotor yarn is coarser than carded or combed yarn. The count of rotor yarn is very low. Most of rotor yarn count is below 20’s but highest yarn count may be 40’s . Coarser fabric is formed by rotor yarn. Most of the jeans or pant is made by rotor yarn. Denim is fully depends on rotor yarn. The price of rotor yarn fabric is very low than combed and carded yarn fabric.

Rotor yarn manufacturing flow chart is given below:


Fiber/Bale →    Blow Room →     Lap/Chute

Lap/Chute    →   Carding   →   Sliver (Carded)

Carded Sliver →  1st Drawing frame   →   Drawing Sliver

Drawing Sliver   →   2nd Drawing frame →   Drawing Sliver

Drawing Sliver   →   Rotor Spinning   → Rotor Yarn





In modern rotor spinning line; blow room and carding machine are use at a time. This technique is called “Chute to feed card” or “Chute to feed drawing”.

Rotor spinning number is less than combed or carded spinning. Low graded fiber spin in rotor spinning.
