Process Flow Chart For Cotton Yarn Dyeing | Light Shade Cotton Dyeing (Less Than 1%)

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%).

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

Absorbency test of sample

Ok

Dyeing period

Add wetting agent, anti-foaming agent, sequestering agent and run at 600 C for 10 min

Color dosing at 600 C for 20 min

Color migration at 600 C for 30 min

Salt dosing at 600 C for 20 min

Run the machine for 20 min at 600 C with color and salt

Soda dosing at 600 C for 40 min

Cotton dyeing at 600 C for 50 min

Check sample

Ok

Drain

Rinse for 10 min

Add acetic acid for neutralization and run for 10 min at 500 C

Drain

Add washing chemical and run at 900 C for 20 min

Wash sample check

Ok

Drain

Rinse for 10 min

Add fixing chemical and half acetic acid, run at 500 C for 20 min

Add softening agent and rest half acid, run at 600 C for 20 min

Check finished sample

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.
