Dyeing Procedure of Reactive NA type - High Perspiration Light Fastness Reactive Dye
Reactive NA type
(High Perspiration Light Fastness)
Special Properties:
Excellent light fastness and perspiration light fastness especially for pale shade.
Good washing-off property.
Good compatibility and reproducibility.
Good build-up.
No need to add "Alkali" during dyeing process.
Dyeing Process:
Start from 25 to 30 degree C
Add NA Dye, Salt, Stabilizer MTB
Run for 20 minutes
Raise temperature from 30 degree C to 85 degree C, 1 degree C per minute.
Dyeing at 85 degree C for 30 minutes
Washing – Soaping – Washing
Soaping Process:
Washing at 50-55 degree C X 10 min.
Soaping at 95 degree C X 15 min.
Cold rinse
Cold rinse
Dosage of Salt and Stabilizer MTB
Dyeing depth (o.w.f.)
Below 0.25% o.w.f., salt 10g/l to 20g/l, Stabilizer MTB 1g/l
From 0.25% to 0.5% o.w.f., salt 20g/l to 30g/l, Stabilizer MTB 1g/l
From 0.5% to 1.0% o.w.f., salt 30g/l to 50g/l, Stabilizer MTB 1g/l to 1.2g/l
Above 1% o.w.f., salt above 50g/l, Stabilizer MTB 1.2g/l
Remarks:
Reactive NA dyes are sensitive to peroxide even only 5 ppm residue, recommend using our peroxide killer to remove peroxide residue.
