Dyeing is the most critical task for a textile engineer. Acrylic cotton dyeing is the double part dyeing process. Here dyeing is done one part to another. It needs to match cotton part and acrylic part then dyeing will be completed.
Flow chart of acrylic cotton dyeing is as follow:
Carrier and vessel washed by hydrose and caustic at 1000 C for 20 min
↓
Load the package in the carrier and feed in the vessel
↓
Add wetting agent, anti foaming agent, sequestering agent and run at 600 C for 10 min
↓
Water solution drain
↓
Add wetting agent, sequestering agent, soda ash and hydrogen peroxide and run at 1100 C for single yarn and 1150 C for double yarn for 20 min
↓
Drain
↓
Add peroxide killer and run at 900 C for 10 min
↓
Peroxide check in the package
↓
Drain
↓
Add acetic acid for neutralization and run for 20 min at 500 C
↓
Drain
↓
Take sample and check absorbency
↓
Ok
↓

↓
Add leveling agent and acid, run at 600 C for 10 min
↓
PH check
↓
Color mixing at 700 C for 40 min
↓
Color dosing at 600 C for 20 min
↓
Acrylic dyeing at 850 C at 20 gradient for 20 min
↓
