“…Polyester (polyethylene terephthalate, PET), a thermoplastic polymer, is the most commonly used manmade fibre and find applications in vast areas from clothing, household items, containers, food packaging, to functional textiles (Ingamells, 1993). Their major characteristics include excellent dimensional stability, high abrasion and wrinkling resistance, good thermal stability and chemical resistance (Shen et al, 2017).…”

Purpose The purpose of this study is to investigate the possibility of dyeing polyester (PET) fabric with natural dye extracted from annatto seeds using high temperature dyeing method. Design/methodology/approach PET fabric was dyed with annatto extract by varying dyeing parameters (temperature, time, pH and dye concentration) to determine the optimum dyeing conditions. The influences of KAl(SO4)2, FeSO4, gallnut mordants or a commercial UV absorber on colour yield and fastness properties were further studied. Findings Optimum results were obtained when the fabric was dyed at 130°C for 30 min in a dyebath containing 15 per cent (owf) annatto dye at pH 6. The dyed fabric had an orange shade and exhibited good to excellent wash, crock, perspiration fastness and fair light fastness. Further dyeing with mordants or UV absorber mostly resulted in lower colour yield and similar fastness properties. Research limitations/implications Although the light fastness was slightly improved to moderate level for the sample with UV absorber, a noticeable colour staining on cotton portion of multi-fibre fabric occurred when subjected to standard washing test. Compared to C.I. Disperse Orange 73, the annatto dye exhibited comparable colour fastness but had inferior light fastness when dyed at approximately the same colour strength. Originality/value Natural colourants from annatto seeds can be used to dye PET fabric at high temperature without mordants, yielding deep orange shade and satisfactory fastness properties. This study provides a promising application to reduce the environmental impact of synthetic dyes.

“…Sicardi et al proposed an experimental method for evaluating the diffusion coefficient of disperse dyes in PET films using the “film roll method.” However, the method is only applicable to the exhaust dyeing process and does not deal with the interactions between the dye and PET. Shen et al found that the dyeing performance was closely related to the structure and intermolecular interactions of azo dyes . The crystal structures of disperse red 65 and disperse red 73 have been studied by Lee et al using X-ray diffraction analysis .…”

“…Shen et al found that the dyeing performance was closely related to the structure and intermolecular interactions of azo dyes. 17 The crystal structures of disperse red 65 and disperse red 73 have been studied by Lee et al using X-ray diffraction analysis. 8 The results show that intramolecular hydrogen bonding could enhance the planarity of dye molecules, and there are π−π interactions between dye molecules, while the work mainly focused on the interactions between single crystals of the dye.…”

The diffusion behavior of a typical disperse dye, disperse red 9 (DR 9), in the polyethylene terephthalate (PET) film at different temperatures was investigated by attenuated total reflection–Fourier transform infrared spectroscopy and 2D correlation spectroscopy (2Dcos) analyses. According to the Fickian diffusion model, the calculated diffusion coefficients of DR 9 in the PET film at different temperatures were observed to increase with temperature, which might be attributed to the increased free volume and thermal motion in the PET matrix and the rapid movement of DR 9 molecules at higher temperatures. In-detail analysis of the diffusion spectra discerned various kinds of molecular interactions, that is, intramolecular hydrogen bonding interactions of DR 9 and dipole–dipole and π–π interactions between DR 9 and PET. Among these, the dipole–dipole interactions between CO groups of DR 9 and PET occurred first and played a vital role during the diffusion process of DR 9, as deduced from the sequence order of group motions in 2Dcos analysis.
