Lignosulfonate Dispersant is used as a dye dispersant

Lignosulfonates are separated and purified from natural plants, so they are called "green" chemical products. Lignosulfonate is harmless to human body and animal and easy to degrade.

In the printing and dyeing process, the sodium lignosulfonate is added before the drying of the dye cake to prevent the particles from flocculating, the particles are easy to separate, and have a certain washing effect. The formed filter cake is easy to grind, hinder the dye precipitation in the dye bath, and help the color agent to disperse evenly into the cloth, and finally achieve uniform color.

High performance dye dispersant is a high molecular weight lignosulfonate fine graded and purified from natural plants through microfiltration, ultrafiltration and nanofiltration, combined with self-developed condensation process production of high-tech products, products natural, green, low carbon, environmental protection. High performance dye dispersants are used in the processing of disperse dyes and VAT dyes, and can be used as dye bath dispersants. The product has a high degree of sulfonation and good grinding effect, which makes the dye particles shrink rapidly. High molecular weight, excellent heat stability, heat resistance temperature can reach 150℃; The phenol hydroxyl group is moderate and has excellent high temperature dispersion stability. Product pure height, light contamination of fiber; The reducibility of parazo dyes is low and the reducibility of parazo dyes is low. The dosage can be 30 ~ 70% to achieve the dispersion effect and save production costs.

Lignosulfonate powder is mainly used for dispersion and filling of disperse dyes and VAT dyes. It has good grinding effect, good dispersion, thermal stability and high temperature dispersion stability, light fiber contamination, small reducibility of parazo dyes, no phosphorus, no formaldehyde, no APEO, no quinoline, and biodegradable. It can be used as a filler for acidic and reactive dyes.

There are many products of lignosulfonate dye dispersants, which are used in different dyes according to the different base types and molecular weights of lignosulfonates. It mainly plays a dispersive role, and some products can also be used as fillers, which are non-toxic, harmless and easy to biodegrade.
