“…Polyester textiles (PETs) as synthetic fibers dominate the garment and textile industry . A disperse dye is used in the presence of a carrier to dye polyester at high pressures and temperatures. − Polyester fabric dyeing calls for large amounts of water and chemical additions (dispersing agents and surfactants), which improve the solubility of the dye in the water phase. Dyeing of polyester produces a significant volume of water that is tainted with dye, which is extremely harmful to the environment. , …”

A very promising green chemistry concept that should gain more traction is the introduction of semiprepared azo dyes, which are made by modifying natural extracts with the azo group. This would reduce the dependency on toxic and nonbiodegradable synthetic dyes while also giving economic value to agricultural wastes. In the current study, an extract of peanut red skin was used as an agro-waste and a source of polyphenols to prepare azo dye by coupling it with a diazonium salt of ρnitroaniline. Then, the prepared dye was used to dye and improve the functional properties of natural cellulosic (cotton) and proteinic (wool) as well as synthetic (polyester) fabrics by using microwave irradiation, with a focus on the kinetic and isothermal adsorption aspects of dyeing processes. The effect of different parameters on fabric dyeability was studied using K/S and the CIE L* a* b*. The effect of dyeing on the multifunctional properties of dyed fabrics was investigated. The adsorption kinetics, isotherms, and mechanism studies of the dyeing process were investigated. The results show that after the fabrics were dyed with the prepared dye, a decorative color was obtained. The dyed fabrics showed very good fastness properties. The dyed fabrics showed excellent UV protection, excellent antimicrobial activity, and very good antioxidant properties. The adsorption kinetics was accurately represented by the pseudo-second-order kinetic model. The Temkin and Nernst models with the best correlation coefficients were discovered to be the most acceptable isotherm models.

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 the dyeing system. In this part of the paper, a novel plasticisation model of dye diffusion is proposed which reflects the crucially important mechanistic role that water‐induced fibre/polymer plasticisation adopts in the diffusion of disperse dyes within polyester and other types of polymeric material.

Polyethylene terephthalate (PET) fibre, widely utilised across diverse industries, suffers from inherent drawbacks such as inadequate moisture absorption, limited hydrophilicity, and susceptibility to static electricity. To address these limitations, Porel fibre has emerged as a novel modified polyester fibre that incorporates flexible aliphatic polyester into its macromolecular chain. This innovative design not only overcomes the deficiencies of PET fibre but also enables it to be dyed using cationic dyes or disperse dyes under atmospheric pressure conditions. However, the investigation of the dyeing process of cationic dyes on Porel textiles remains relatively scarce. In this work, response surface methodology (RSM) was used to optimise the dyeing process of Porel fabrics with C.I. Basic Blue 162. The effects of dyeing temperature, dyeing time, and dye concentration on exhaustion percentage and colour strength (K/S value) were investigated using the Central Composite Design (CCD) method. The optimal dyeing process condition was as follows: a dyeing temperature of 96°C, a dyeing time of 51 min, a dye concentration of 3.6% owf, a dye solution pH value of 4–5, and a liquor ratio of 1:20. Under the optimal dyeing process conditions, the Porel fabrics achieved an exhaustion percentage of 96.2% and a K/S value of 36.0. The aforementioned efforts endow Porel fibre with high‐quality dyeing capabilities and broaden the application prospects of polyester textiles.
