| Conclusion: | Qualified | |||||
It is maily used for vat dye dyeing, reactive dye dyeing and acid dye dyeing;
It can work as dispersant for acid staining pad and pigment pad dyeing;
It is auxiliary for reducing dye powder and slurry;
It can also be used in leveling agent in dyeing industry
1)As dispersant in disperse dye, vat dye, reactive dye, acid dye and leather dye. It has good grinding effect,
hydrotropy and dispersibility.
2)As dispersant in textile printing and dyeing industry: pigment pad dyeing of disperse dye;vat acid dyeing of disperse dye; dye for silk and feather mixture; soluble vat dye dyeing; It also can be used as dispersant for disperse dye
and lake making; filler for commercial dye etc.
3) As auxiliary tanning agent in leather industry, used together with tanning agent (ratio 1:10) to avoid tanning agent stick with leather. Can also help to disperse dye to get a better appearance in color.
4)As dispersant for paper industry. After adding NNO into wood pulp to avoid the stain from the condensation of asphaltum, resin and other material, 0.2%-0.5% of the wood pulp's weight as dosage is preferable. Can work as precipitator for animal size, 20%-30% of the size's weight as dosage is preferable.
