Strength adjustment of reactive dyes

Strength standardisation of reactive dye powder formulations often requires 30% to 40% strength reduction. Borregaard lignin-based biopolymers are sustainable and high-performance additives for adjusting the strength of different reactive dyes. Our products have shown significant benefits compared to other options.

Fibre-staining tests were conducted on reactive dyes to illustrate the effectiveness of our biopolymers as cutting/dispersing agents for adjusting strength.

In this figure, the Delta E shows that our lignin-based biopolymer allows cotton dying closer in shade to the ultrafiltered crude Reactive Red 120 than the tested synthetics.
