[ДСТУ] Koval M. Repeated Use of Purified Wastewater in the Dyeing of Polyether Fabrics with Dispersed Dyes. French-Ukrainian Journal of Chemistry. 2024. Vol. 12, no. 1. P. 118—138. DOI: 10.17721/fujcV12I1P118-138 (date of access: 25.07.2026).
The article presents the results of reuse of treated wastewater from the dyeing and finishing production in the technology of fabric dyeing. The wastewater is purified by adsorption using natural zeolite, followed by coagulation and flocculation. The purified water is reused in the process of dyeing polyester fabric with dispersed dyes of Dark Blue Z, Red 2C, Yellow Stable 2K. They ensure the intensity of fabric coloring at 95-99.9% compared to 100%. The stability of the obtained color is at the level of 2-4 points according to the greyscale. The double treatment of the same wastewater makes it easy to dye Polyether fabric with dispersed Dark Blue Z dye.
