Wool carbonization

  1. 1. Impurities.Scouring .Vegetable Matter .Carbonization .Techniques.New Technologies.Advantages & Disadvantages.
  2. 2. Impurities Natural AcquiredOil Fat Sand Pollen
  3. 3. Vegetable Matter VM Discounts MediumFine Wool Wool
  4. 4.  The object of the carbonization process is the removal of vegetable matter from wool. Processing StagesScouring of the raw wool with non-ionic detergent.Rinsing.Immersion in a long bowl containing 5-7% (w/v) sulphuric acid, 1-2 g/L detergent at 20- 30C.
  5. 5.  Double squeezing and/or continuous centrifuging prior todrying. Drying at 60-80C to a low regain. Baking at 95-120C to carbonize the VM Pass through heavy fluted rollers to crush the embrittledVM Convey to a rotating shaker/de-duster to remove thecharred VM dust Pass through a neutralizing bowl usually containingsodium carbonate
  6. 6.  Rinsing with a small addition of detergent. Bleaching with hydrogen peroxide at approximately pH5 with formic acid. Final drying
  7. 7. The traditional system Fabriccarbonizing Carbosol system
  8. 8. The traditional system 5-7.5%6-8% 5-65%
  9. 9. Carbosol system
  10. 10. Control the carbonization process Veryimportant why ?
  11. 11. Acidising.Moisture removal. Drying/Baking .Burr crushing and dedusting. Neutralization
  12. 12.  Ensures full cleaning of fibers from impurities The fiber length isn’t changed The wool production as compared with the mechanical method is increased by 1- 1.3%. The quality of yarn and fabric improved. wool carbonization is more effective than burr picking in burr pickers.
  13. 13.  The harsh process described cause considerable fiber breakage and loss rendering any long wools used, suitable for the woolen system only.
