Dyeing Mechanism of Disperse Dyes

Since disperse dyes are insoluble in water and only use water as a medium, they are directly dissolved in fibers during dyeing, using fibers as a solvent, and dyes as a dissolution process of the solute. Since both the solvent and the solute are solid, it is called "solid solution theory".

Polyester fiber has the characteristics of compact molecular structure, high crystallinity, strong hydrophobicity and high negative potential, and lacks functional genes combined with ionic dyes. For this reason, in order to solve the difficulty of dyeing polyester fibers and increase the diffusion rate of dyes in the fibers, in addition to the use of disperse dyes with small molecular weight and micromolecules, the above three dyeing methods should be used in the dyeing method.
