Summary: The molecular simulation software was used to analyze the adsorption of sulfomethylated lignin (SAL) on dye surfaces. Different SALs with varying sulfonic group contents were prepared and characterized. SAL1.53 was determined to be the best dispersant for nano disperse dyes in digital printing technology. Increasing sulfonic group content in SAL resulted in increased adsorption mass, rigidity of the adsorbed layer, adsorption force, and absolute zeta potential value.

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: Textile effluents, especially from dyeing processes, are highly polluting and difficult to treat. This study explores the possibility of reusing the waste, such as dyes, by recovering them from water and using them as raw materials for new dye baths. Hybrid nanoclays obtained from dye adsorption were used in the study, and their effectiveness in adsorbing anionic, cationic, and non-ionic dyes was analyzed. The results showed that the adsorbed dyes can be successfully reused in new dyeing processes, and the color degradation tests on different textile substrates yielded consistent results with conventional dyes.

Summary: Novel bisazo disperse dyes based on symmetrical structures were successfully synthesized, showing improved dyeing performance on PET fabrics by introducing 1,4-butanediol as a soft chain to enhance affinity with fibers. The use of ester groups in both dye molecules and fibers, along with increased molecular size, resulted in stronger Van der Waals forces and hydrogen bonding, contributing to the enhanced dyeing properties.

Summary: A series of fluorescent phthalimidylhydrazone disperse dyes based on pyrrolinone esters were synthesized and characterized. The dyes showed high fluorescence intensity and color fastness. By modifying the length of the N-alkyl substituent, the color yield of the dyes on poly(ethylene terephthalate) fabric can be improved. Furthermore, the dyes demonstrated excellent color fastness after a mild alkaline treatment, which is environmentally friendly.

Summary: Coating nonwoven fabric with graphene oxide nanosheets using an elevated temperature padding method resulted in effective removal of dye particles from water in a shorter amount of time. The higher amount of GON fixed on the fabric surface through this method led to increased photocatalytic activity and allowed the coated fabric to be used repeatedly for dye removal. The successful formation and reduction of GON to rGON on the fabric were confirmed through various microscopy and spectroscopy techniques.

Summary: The replacement of inorganic salt and alkali in reactive dyeing of cotton textiles with organic biodegradable compounds has been studied. This study investigated the use of tetra sodium salt of glutamic acid diacetic acid (GLDA-Na-4) as an exhausting and fixing agent in the batchwise dyeing of cotton garments. The results showed that GLDA-Na-4 achieved a maximum K/S value of 25.5 and fixation rate of 90.74% in laboratory scale experiments. Additionally, the use of GLDA-Na-4 led to significantly reduced total dissolved solids (TDS) and chemical oxygen demand (COD) in the effluent samples compared to inorganic chemicals. The colorfastness and tensile strength of the dyed samples were similar to those achieved with inorganic chemicals.
