Product name:Color fixing soda substitution WS-037
Appearance:White powder or granular
2.Physical and Chemical Properties:
PH Value(1% aqueous solution): 10.8±0.5(2% aqueous solution)
Solubility: Miscible with hot water in any percentage
1.Replace soda ash, trisodium phosphate, caustic soda liquid to be used for reactive dyeing.
2.When diluting it to use, there will not cause powder dusty and pollution like soda ash.
3.The dyestuff and auxiliary can be put in together in normal temperature. It is easier to operation and management.
4.Have buffer solution property, the PH Value in the dye bath is stable when dyeing, improve color matching, reduce dyelot chromatism
5.It is easy to clean after dyeing, no residual on the fabric, no chromatism after soaping.
6.Less dosage, it is about 1/8 or 1/10 of soda ash, easily extracted, reduce workload, improve working efficiency
Usage and reference dosage
→before using, WS-037 shall be diluted 10 times above in the vice cylinder
→the dosage of WS-037 shall be adjusted according to bath ratio, and also shall be adjusted according to the dosage of dyeing stuff, suggest that the dosage shall be 1/8 or 1/10 of soda ash, 1/10 for large bath ratio, 1/8 for low bath ratio to conversion. The lowest dosage shall be 1g/L. the dyeing process is the same with soda ash.
→for reactive dyeing fixing, putting 3g/L soda ash light firstly, and if the dosage of soda ash is X g/L in traditional process, then the dosage of Substitutive Soda WS-037 per litre is (X-3)/10 .
When using WS-037 to dyeing dark color or brown color, the dyeing color will be lighter
1.Adding some Sodium Sulphate Anhydrous (about 8-12g/L), or extend the heat insulating time about 20-30 minutes
2.Adding 1g/L soda ash before adding dyeing stuff
5.Storage and shipping:
Store in a dry and ventilated place
Should avoid strong vibration in transportation
