Product introduction:

This product is composed of naphthalene sulfonate formaldehyde condensation sodium salt, has excellent dispersion and protection of colloidal properties, but no permeable foaming and other surfactants. Product stability: acid resistance, alkali resistance, heat resistance, hard water resistance, inorganic salt resistance. Affinity for protein and polyamide fibers. In the printing and dyeing industry, it is mainly used for rolling and dyeing of VAT dye suspension, cryptic acid dyeing, dispersive and soluble VAT dye dyeing. It can also be used to dye silk/wool interleaved fabrics, so that there is no color on the silk. The dye industry is mainly used as dispersing agent, rubber emulsion stabilizer, and leather assistant tanning agent in the manufacture of dispersing and lake.

Application technology:

This product is used as a Dispersing and filling agent for Dispersing and VAT dyes, which Dispersing agent or VAT dye particles can be processed in a grinder with Dispersing agent and dye. The amount of Dispersing agent NNO-L is 0.6 to 3.5 times of the reduction dye or 1.7 to 2.5 times of Dispersing agent, which can also be left to be used as a filler in the commercialization of dyes. VAT dye dyeing suspension Pad dye: Dispersing agent NNO-L 3.5 to 5.5g/L is added to Dispersing agent NNO-L 17 to 22g/L in the reduction bath. In general, 0.6 to 1.7g/L is added to Dispersing agent polyester in high temperature and high pressure dyeing bath. Ice dye dyeing is used to improve levelling and Rubbing fastness. The amount of Dispersing agent in the chromophenol base bath is generally 2.5 to 5.5g/L and 0.6 to 2.5g/L in the chromogenic bath Dispersing agent NNO-L.
