Introduction :
It is multiple alkali and suitable for reactive dyeing. Replace soda ash and does not contain formaldehyde. It is powder and surmounts the shortage of liquid alkali which is unstable and low fixation because of the lack of sodium.
Specifications:
Components :Multiple alkali
Appearance :White powder
Solubility :Easy solved in warm water
Characteristics :
1. Easy application,1/8 to 1/10 measure to Soda Ash which means saving labour strength and Storage room.
2. The fixing performance is slow and stable,Improve the leveling problem specially for T.Blue and green color.
3. Fastness is same as that of Soda Ash.
4. Reproducibility from the lab to the bulk is excellent.
5. Environment-friendly.
6. Save 1/3 cost compared with Soda Ash.
Testing Method :
When dyeing put the substitute in the machine by twice then measure the pH value then gets the result as following;
(pH value of the water:7.2)
Dosage | 17% | 33% | 100% | End of dyeing | |
HK-J218 2.5g/L | PH | 11.10 | 11.80 | 12.08 | 11.72 |
Soda Ash 20g/L | PH | 11.05 | 11.27 | 11.42 | 11.11 |
From the data we conclude that substitute has good buffering performance.
The pH value is lower at beginning which improve the leveling.
Usage :
Marks :
1. The dosage is 1/8-1/10 of Soda ash for all depth of shade.
2. In order to match the shade and the depth with that of Soda Ash:
A. 10% additional salt for the lab trial
B. Extend 10—15 min for the lab trial.
C.For bulk trail there is no need for these two factors.
3. Compared with soda ash. It is easy to wash which improve the
fastness.
4. The usage and the procedure are just for reference.
5. Pay attention to the veracity because of the little dosage.
6. Depend on the demand you can extend the fixing time in order to get better purpose.
Procedure for Pad Batch Dyeing:
Padding Dyes→Dry→Padding Alkali→Steaming(100℃~102℃×30″~60″)
Dyes | Soda Ash | Substitute |
<10g/l | NaCL 100g/l Na2CO3 20g/l | NaCL 100g/l ALF 2.8~4g/l |
>10g/l | NaCL 200g/l Na2CO3 40g/l | NaCL 100g/l ALF 5.5~8g/l |
Packing : 25 Kg PP Bags.
Storage : A shelf life of 6 months stored in cool, dry warehouse
