Summary: This paper investigates the impact of substituents on the coloration process in a waterless dyeing system through molecular dynamics simulations. The results reveal that introducing cyan and N-cyanoethyl groups can reduce the diffusion coefficient and solubility of disperse dyes, while increasing the interaction energy between dyes and fibers, thereby enhancing adsorption efficiency and dyeing uptake.

Summary: This study investigated the dispersion mechanism of polycarboxylic acid dispersants for disperse dyes using molecular dynamics simulations. The results indicate that the hydrophilicity of the dispersant depends on the maleic acid residues, while the hydrophobicity of the styrene residues drives the adsorption of dispersants onto dye surfaces. The presence of branched chains plays a crucial role in the binding of dispersants to dye crystals. When designing dispersants for disperse dyes, it is important to consider both the improvement of hydrophilicity and charge repulsion for maintaining dispersion stability in water, as well as the binding force between dispersants and disperse dyes.

Summary: In this review, various methods for the preparation of new disperse dyes in an environmentally safe and economical way are presented. The use of microwave technology has shown to be a rapid and efficient method compared to conventional methods, with the added benefit of reducing the use of harmful organic solvents. Additionally, the use of microwave and ultrasound technologies in dyeing polyester fabrics at lower temperatures not only saves energy but also provides a higher color depth. Furthermore, the strategy of treating polyester fabrics with nano-metal oxides enhances their properties, such as anti-microbial activity, UV protection, light fastness, and self-cleaning properties. The newly synthesized dyes also exhibit strong biological activity.
