Textile Wastages | Wastages in Ring Spinning | List of Wastages in Combing/Simplex/Ring Frame


In practical,


Input – Output = Wastage


List of Wastage in Combing:



  1. Noil:                           As per desired & quality of the end product to be produced.

  2. Minilap Wastage:         0.25%

  3. Sliver Wastage :           0.25%

  4. Roller Wastage :          0.25%

  5. Fly Dust:                     0.10%

  6. Sweeping:                   0.20%

Wastages in Simplex/Speed Frame:

  1. Sliver

  2. Roller Waste/Bonda

  3. Pneumaphil Waste

  4. Roving Waste

  5. Sweeping Waste

  6. Clearer waste

  7. Invisible Waste

Note:Above 0.50% of total amount of wastage is not acceptable

Wastages in Ring Frame:



  1. Pnemaphil:                      0.20-0.30%

  2. Bonda:                           0.20-0.30%

  3. Roving waste:                 0.10-0.20%

  4. Thread waste:                 0.10-below

  5. Fly dust:                         0.20%

  6. Sweeping waste:            0.20%

Note: Total wastage is not more than 1%


Concept of Wastage:



  • Wastage Control(Previous Concept) = Wastage Production+Wastage Reduction

  • Wastage Management (Present concept) = Wastage Production+Wastage Utilization


Wastage Reduction Procedure/ Factors for Wastage Reductions:


  1. Raw materials selection

  2. Spindle speed

  3. Setting(Rollers, R/T, Traveller cleaner etc)

  4. Twist of yarn

  5. Machinery condition

  6. RH% and Temperature

  7. Proper material handling

  8. Adequate supervision
