Effect of the degree of esterification of disperse dyes on the dyeing properties of polyethylene terephthalate in supercritical carbon dioxide

Preparation of high-performance monoazo disperse dyes bearing ester groups based on benzisothiazole and their dyeing performance on polyester fabrics

“…Disperse dyes containing ester groups can be hydrolyzed to water-soluble dyes under alkaline conditions, which can also avoid staining during the washing process. [6][7][8] Disperse dyes bearing ester functions were developed to decrease the staining tendency behaviors on microbers, and the thermomigration problems exist in heatsetting and functional nishing process can also be reduced by introducing ester moieties. Aromatic heterocyclic structures have attracted great attention, which is attributed to their higher tinctorial strength, and brighter color shades on the synthetic fabrics.…”

Molecular Dynamics Simulation and Structure Changes of Polyester in Water and Non-Aqueous Solvents

“…Polyethylene terephthalate (PET, polyester) fiber has a very tight structure and strong hydrophobicity. The cross-section of the PET fiber is circular under the microscope, its longitudinal thickness is uniform, and its surface is smooth [ 1 , 2 , 3 ]. During the PET dyeing process, the dispersed dye must enter the PET fiber through a narrow gap, which poses great difficulty.…”
