To evaluate the effectiveness of ECOFAST™ Pure as a cationic fixing agent to enhance dyeing characteristics and reduce environmental impact.
Pre-application of ECOFAST™ Pure at 5%-10% weight of fabric prior to dyeing.
Comparison of dye exhaustion rates with traditional tannic acid/alum mordanting and ECOFAST™ modification.
Testing dyeing at lower temperatures (60°C) for improved outcomes.
Cochineal dye exhaustion reached ~99% with ECOFAST™ Pure compared to ~62% with tannic acid/alum.
Lower temperature dyeing improved both dye exhaustion and color strength relative to traditional methods.
The addition of Matexil DA-AC improved color strength despite decreasing dye exhaustion.
