Process Selection
For disperse dyeing the procedure is same in laboratory but in cotton there are different method due to the properties of the fabric which become uneven especially light shades due to small quantity of dyes to be distributed to the fabric. Following procedures are:
- standard process
- isothermal
- migration
- rapid
- rapid migration
- portion wise salt (HT) migration
For Disperse Dyeing
Chemicals and auxiliaries in disperse dyeing in all brands are similar and dyeing temperature mostly is 1320C.
- dispersing agent : Setamol WS / Setamol BL — 0.8- 1.0 g/l
- pH adjuster : acetic acid / formic acid — 0.5 – 1.0 cc/l
- pH required and to be maintain is 4.5 – 5.0
