Green Rheology Modifiers: Enhancing Dye Printing Efficiency using Acrylated Flaxseed-Based Thickeners

Thickeners control pastes rheology, dye transfer, and fixing efficiency, making them essential in textile printing. The
stability, color compatibility, and reproducibility of conventional natural and modified polysaccharide thickeners
are limited, while synthetic versions pose toxicological and environmental issues. In order to improve performance
in Direct, Reactive, and Disperse dye printing, this study examines flaxseed gel as an environmentally acceptable
thickener and assesses derivatives modified by acrylation. The findings show that acrylated modified thickeners
provide better color strength and washing fastness than gum indalca, ZnO and TiO₂ modified thickeners. Notably, a
40.27% increase in color strength is achieved in Reactive dye printing, with consistently high performance
observed across all dye classes. These findings highlight the strong potential of acrylated flaxseed-based thickeners
as sustainable, high-efficiency rheology modifiers, contributing to advancements in green and performance-driven
textile printing technology.
