Application Field of Dispersing Agent NNO CAS 9084-06-4
The Dispersing Agent NNO CAS 9084-06-4 is mainly used as a dispersant in the dyeing of disperse dyes, reactive dyes, acid dyes, and leather dyes. It has excellent emulsifying, solubilizing and dispersing properties; it can also be used as a dispersant in textile printing and dyeing, wettable pesticides, papermaking dispersants, electroplating additives, water-soluble coatings, pigment dispersants, water treatment agents, carbon black dispersants, etc. In industry, Dispersing Agent NNO CAS 9084-06-4 is mainly used for the wetting suspension dyeing of reactive dyes, the dyeing by the masking acid method, and the dyeing with dispersible and soluble reactive dyes. It can also be used for the dyeing of silk/wool interwoven fabrics to prevent color transfer on the silk. In the dyeing industry, Dispersing Agent NNO CAS 9084-06-4 is mainly used as a diffusion aid in the manufacturing of dispersants and color pigments, as a stability agent for rubber emulsions, and as a leather finishing aid.
- Dispersing Agent NNO CAS 9084-06-4 is used as stabilizer, dye diffuser and levelling agent for rubber industry latex.
- Dispersing Agent NNO CAS 9084-06-4 is also used as water reducing agent and reinforcing agent for concrete, dispersant and industrial tanning agent for leather.
- Dispersing Agent NNO CAS 9084-06-4 is mainly used as a dispersant for VAT dyeing, acid dyeing or suspension pad dyeing.
- Dispersing Agent NNO CAS 9084-06-4 can also be used as diffusion agent of fine powder or paste of VAT dye, levelling agent and assistant tanning agent of leather industry, and early strength water reducing agent of cement.
package of Dispersing Agent NNO CAS 9084-06-4
For Dispersing Agent NNO CAS 9084-06-4, it is powder form. The 25-kilogram woven bags or 650kg jumbo bag are lined with plastic bags for storage and transportation. The finished packaged dispersing agent NNO should be handled with care during loading and unloading, and should be stored in a cool, dry and well-ventilated warehouse.
The pH value of Dispersing Agent NNO CAS 9084-06-4 in dyeing polyester
- When dyeing polyester, the pH value of the dye bath using dispersing Agent NNO is generally controlled at around 5 - 6.
- The pH value of the Dispersing Agent NNO CAS 9084-06-4 itself is slightly alkaline. However, in the actual application of dyeing polyester, in order to achieve a better dyeing effect, buffer agents such as acetic acid are usually added to adjust the pH value of the dye bath to the weak acidic range. Under weakly acidic conditions, it is conducive to the adsorption and diffusion of disperse dyes on polyester fibers, improving the uniformity and color fastness of the dyeing process. At the same time, it can also enable the Dispersing Agent NNO CAS 9084-06-4 to better exert its function as a disperse dye and prevent dyeing from coagulating and precipitating.
