It is mainly applicable to whitening and brightening of polyester fiber and the blends, especially to whitening of polyester fiberknitting at low-temperature (95-100 ℃).
Liquor ratio : 1:10-20
Dyeing temperature: 95- 100℃Dyeing time: 30-40min
PH value : 4.5-5.5 (adjusted with acetic acid)
Procedure : add additive, acetic acid (adjusting PH: 4.5-5.5) and c.i.199 into the dye bath according to the formula , raisetemperatur e to 95-100 ℃ as the rate of 2-3℃/min, keep constant temperature for 30-40min → drop in temperature → washing
- dehydrat ion and drying (80- 100℃),its whiteness can meet the user ’s requirem ent . If the user has fixing machine, carry outpre-dr ying (80- 100℃) and curing (170- 175℃,30-40s) after washing and dehydration, then whiteness will be better.
Procedure: 2 dips 2 nips (pick up: 70%) → pre-drying ( 100℃) → curing and thermo -fixing (175- 180℃,30 seconds)
