Cotton Dyeing
Yarn dyeing is one type of package dyeing which is done in different dyeing machines. However, different shaded yarn s produced by the dyeing process. On the yarn dyeing floor; the process for cotton yarn can be vary depending on the individual procedure of a textile engineer or a dyeing master. I have given a process flow chart for 100% cotton dyeing. This sequence is applicable for producing light shade (less than 1%).
Process Flow Chart For Cotton Yarn Dyeing
Dyeing sequence for 100% cotton for light shade:
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, caustic soda 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
↓
↓
Ok

Drain
Oh, my friends, this is my own observation if you have a better one let me know the sequence of cotton dyeing for light shade. I think this will give you a better way to get better dyeing performance.
