Flow Chart of Rotor Yarn Manufacturing Process

Rotor Yarn: 

Rotor spinning is commercially more widely used because of a wider range of yarn counts. The rotor spinning process is fully different from carded yarn manufacturing or combed yarn manufacturing. Rotor yarn is coarser than carded or combed yarn. The count of rotor yarn is very low. Most of the rotor yarn count is below the ’20s but the highest yarn count maybe the 40’s. The price of rotor yarn also low from carded and combed yarn. Flow Chart of Rotor Yarn Manufacturing Process is as follows:

Rotor yarn is formed by twisting the rotor by a rotor spinning machine. This yarn can be formed from the short fiber. Normally rotor yarn is coarse. Rotor yarn is also called open-end yarn & Rotor yarn is a widely used yarn in Denim production.Rotor spinning proves the economic source of producing the coarser number of yarns. That satisfies the manufacturer’s profit need. It is an ever-growing sector and the investment requirement will lower than the other spinning systems. But it is in the second place of yarn production technique. It has domination over, all the spinning systems due to its remarkable advantages like higher production, low hairiness, more even yarn with good bulkiness.

Objective of Rotor spinning process:

  • Yarn Coarser than carded or combed yarn
  • Yarn Use for coarser fabric
  • Produced by low graded fiber
  •  Machine speed very high
  • Low count. Generally 20 counts, highest 40s
  •  High productivity
  •  High capital cost
  •  Mainly use to manufacturing Denim jeans fabric
  •  Low price
  •  Less wastage percentage
  •  No need for a Simplex machine
  •  Less labor
  • Low manufacturing coast
