“…This may be attributable to the low number of the negatively charged sites on unmodified fibres, whereas, for modified fibres, the washing fastness was improved (from 3 to 4–5) by the increase of the percentage of grafting. Indeed, this improvement is attributable to the presence of a great number of the anionic sites that are able to ensure electrostatic interactions, to which Van‐Der‐Waals and hydrogen interactions are added [13].…”

Polyamide 6.6 fibres were modified for the improvement of dyeing affinity using a graft copolymerisation method. These fibres were grafted with acrylic acid as monomer. The influence of the chemical modification of polyamide 6.6 fibres on the dyeing properties was investigated using a cationic dye (Red Astrazon 5BL). It was shown that the dye uptake of the modified fibres was greater than that of the unmodified fibres. The kinetic study of the cationic dye used at various grafting percentages showed an improvement of the dye build-up rate, such as its exhaustion. In addition, an increase in the adsorption of the dye quantity fixed on the surface layer of the fibre made up of the grafted molecules was announced. Colour fastness to washing was improved with the grafting percentage. The modelling of the adsorption isotherms using Langmuir, Freundlich and Jossen relations allows the determination of isotherm constants. The results obtained from this modelling study show the existence of several models corresponding to various percentages of grafting.

“…Abolishing of disperse dye on the PET surface and making adjustment to achieve the proper wetness fastness levels are important as well. There is a general acceptance of the technical importance of reduction clearing in order that the accuracy of the colour and the fastness properties could be enhanced, specifically to wet treatments [10].…”

Abstract. In this research, a novel approach has been proposed to remove stain problem from blended fabrics as an alternative option with traditional reduction clearing process. For this purpose, cationic dyeable polyester and cotton blended fabrics were dyed as traditional technique based on formulations approach and the colour strength (K/S), dye uptake (%) and the whiteness index properties were evaluated. The results of color strength indicated that dye was more uniformly absorbed by the blended fabric compared to the untreated fabric. In addition, when untreated fabric was dyed in the presence of a leveling agent (Lyogen DFTN), the K/S and levelness of dye uptake (%) values were enhanced. Finally, very less staining was observed that proved by CIE Whiteness Index values and indicates that formulation (F-IV) has more beneficial to reduce staining from Cotton/CDPET blended fabric (65/35).

“…It has been produced by incorporating sodium-5-sulfo-bis(hydroxyethyl)-isophthalate (SIP) and poly(ethylene glycol) (PEG) into regular polyester. Compared to the normal SIP-incorporated copolyester − (known as cationic dyeable copolyester, CDP), ECDP shows improved boiling dyeability and enhanced hygroscopicity thanks to the increase of ether bond and hydroxyl value from PEG units. However, the further application of ECDP as PET replacement has been limited by the undesired properties, such as poor spinnability, low light fastness, and poor pile-on property in the boiling dyeing processes. , …”

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.
