Biopolymers performance in disperse dyes

You can use Borregaard’s lignin-based dispersants either individually or in combinations to serve your specific needs. Our sustainable primary and secondary dispersants for disperse dyes provide you with improved milling, azo reduction, heat stability and staining properties.

 

 

The staining percentage comes from dividing the sample brightness with the blank brightness. The higher the bar, the more the product stains the textile.

Besides improved cost/performance, utilising Borregaard’s biopolymers may strengthen the sustainability profile of your processes and products.

 

Your choice of dispersant is dyestuff and process dependent and often requires a balancing determination for properties like heat stability, staining and milling efficiency. The figures show that Borregaard biopolymers provide heat stability and are low to moderate in staining. By enabling processing at higher solids, the solution lowers azo bond reduction, improves colouration and increases milling efficiency.
