The main components of disperse printing thickeners are mostly high-molecular polymers, such as polyacrylates, polyurethanes, or surfactants with specific structures (such as fatty acid derivatives). These substances form a three-dimensional network structure through the interaction between molecular chains, thereby increasing the internal friction of the system and resulting in a significant increase in viscosity.
For example, fatty acid derivative thickeners (such as fatty acid diethanolamides) can form micelles in water through hydrogen bonding, further intertwining into a network to achieve a highly efficient thickening effect.
