“…It can be observed in Figure b that the color strength of dyed MCDP increases at first and then decreases with increasing temperature. Generally, a higher temperature could could promote the thermal movement of the dye molecules by breaking the bonds (van der Waals forces, Dipole–dipole bond and hydrogen bond) between polymer chains above T g . Higher color yield obtained with the formation of larger, more accessible voids through which the disperse dye molecules can diffuse more readily.…”

However, as temperature was increased successively, the tendency of the dye molecules to go from the fiber into the dyebath was also enhanced.…”

To obtain sufficient dyeability, dyeing of poly(ethylene terephthalate) fabrics must be performed at high temperature and high pressure or by using a no-eco-friendly carrier at atmospheric pressure, which implies large energy consumption and environmental contamination. In order to improve the sustainability of the dyeing process, a carrier-free and low-temperature dyeing procedure was developed for the poly(ethylene terephthalate) copolyester (MCDP) incorporated with sodium-5-sulfo-bis(hydroxyethyl)-isophthalate (SIP) and 2-methyl-1,3-propanediol (MPD). The results obtained from cationic dyeing at optimized conditions show an outstanding dye utilization (99.0%) with MCDP, which is much higher than that of the conventional SIP-modified copolyester. Meanwhile, the introduction of SIP and MPD contents ensures the large adsorption and fast diffusion of dye molecules into the amorphous region of fibers, allowing an efficient and deep disperse dyeing of polyester fabrics under atmosphere in the absence of carriers. The environmental benefits arising from high quality dyed MCDP fabrics with ultradeep dyeing performance and excellent color fastness through a facile and clean dyeing process are highlighted with the economic ones.

“…Because of their weak migratory capabilities at the boil, these dye classes are applied with retarders. When using retarders, careful monitoring is required to ensure that anionic sites within the substrate are not blocked, limiting dye uptake and making dark hues challenging to achieve [79,80].

Dyes are substances that enhance the appearance of finished goods by providing uniform colour. Dyeing is the application process of dyes that are fixed in textile fibers. The dyeing process uses various steps, including pre-treatment, desizing, scouring, bleaching, carbonizing, degumming, and mercerization. Water is considered the primary medium for applying dyes and other chemicals for this treatment in the dyeing process. The dyeing process contains many toxic chemicals, metals and non-soluble substances, such as wastewater, which is thrown into the environment. It is noted that, during dyeing , around 50-300 liters of water is required for 1 kg of fiber. On the other hand, 1-2 million liters of water are needed every day for 50,000 meters of daily production. This massive amount of toxic wastewater is highly harmful to the environment, human health, aquatic system, soil, air, water, plants, and animals. This review paper states various dyeing processes with different dyes, including acid dye, direct dye, sulfur dye, reactive dye, vat dye, metal complex dye, azo dye, disperse dye, and basic dye. In contrast, it also describes the influencing factors of dyeing processes and methods. Moreover, this review demonstrates the impacts of textile dyes on the environment (water, soil, air emissions, human health) and illustrates possible remedial actions regarding wastewater.

This review concerns the application of disperse dyes to poly(ethylene terephthalate) fibres using aqueous immersion dyeing processes and the roles of both elevated dyeing temperatures and carriers in such dyeing systems. This part of the paper presents a review of the fundamental properties and characteristics of poly(ethylene terephthalate) fibres, disperse dyes and dyeing accelerants. In the next part of the paper, the various theories and concepts which have been proposed to explain the promotional effects imparted by elevated dyeing temperatures and carriers to disperse dye uptake on PET and other types of fibre, are reviewed and analysed, from the viewpoints of the essential physico‐chemical aspects of both the aqueous disperse dye/PET and disperse dye/carrier/PET systems. The final part of the paper will present a dual‐mode mechanistic model of the disperse dye adsorption process which can be used to account for the promotional effects imparted by both elevated dyeing temperatures and dyeing accelerants on disperse dye uptake.This article is protected by copyright.
