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

Winding

Reeling

Bundling

Bailing

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.

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

Combed cotton spinning process is another important spinning process of cotton. Combing is done for adding extra features to the fibers. Higher count yarn is produced by this process. Combed yarn is finer than carded or rotor yarn. Combing is done after carding. Some extra steps are added for combed yarn manufacturing. The price of combed yarn is higher than carded or rotor yarn.

Combed cotton yarn manufacturing process is given below:

 

Fiber/Bale → Blow Room   →     Lap/Chute

Lap/Chute    →   Carding   →   Sliver (Carded)

Carded Sliver →   Pre-Comb Drawing Frame →   Sliver (Pre-Drawn)

Sliver    →   Lap Frame →   Lap

    Lap     →     Comber →       Sliver

Sliver   →     Post-Comb Drawing Frame   → Sliver (Post-Drawn)

Drawn Sliver →    Simplex   →   Rove

Rove    →   Ring Frame   →   Yarn

Winding

Reeling

Bundling

Bailing

 

Combed yarns are made by this process. After ring frame; produced yarns are wind in cone form. In reeling, hank of yarn is produced from cone form. 10 pounds weighted bundle is formed by hank. By that’s bundle 400 pounds weighted final bale is formed.

After producing combed yarn; we can use it for making any types of fabric. The fabric which is made from combed yarn is more comfortable for use. Fineness of fabric is higher than carded or rotor yarn fabric.

 

Process Flow Chart of Carded Yarn Manufacturing Bale Management | Cotton Fiber to Yarn Manufacturing

Cotton fiber is the most common used natural fiber all over the world. Cotton fibers spin for producing yarn for facilities fabric manufacturing. Different spinning process is applied for cotton spinning. Carded yarn manufacturing is one of them. Carded yarn is courser than combed yarn but finer than rotor yarn. So, we need to get knowledge about carded yarn manufacturing process.

Carded cotton yarn manufacturing process is given below:

Fiber/Bale →    Blow Room →     Lap/Chute

Lap/Chute    →   Carding   →   Sliver (Carded)

Carded Sliver →  Draw Frame →   Sliver (Drawn)

Drawn Sliver → Simplex  →   Rove

Rove    →   Ring Frame   →   Yarn

This is the full process chart of carded yarn manufacturing. After ring frame; produced yarns are wind in cone form. In reeling, hank of yarn is produced from cone form. 10 pounds weighted bundle is formed by hank. By that’s bundle 400 pounds weighted final bale is formed.

After producing carded yarn; we can use it for making any types of fabric.
