“…From the perspective of the disperse dye/PET fibre system, in 1954, Schuler and Remington 18 observed that rectilinear, Nernst (aka partition) adsorption isotherms were obtained for the aqueous CI Disperse Red 15/PET fibre system which took the generic form of line I in Figure 1. These findings were subsequently confirmed by other workers for the disperse dye/PET fibre system 19,[22][23][24] as well as for the adsorption of disperse dyes on other types of fibre (e.g., PA, 22,25,26 PP, 27 CA 8,19,[28][29][30] PAN, 31,32 CV, 33 CTA 30 and wool 34 ; see Burkinshaw 5 for a summary).…”

“…Firstly, linear adsorption isotherms of the type represented by line I in Figure 1 have been secured for the equilibrium uptake of disperse dyes on a wide range of different types of textile fibre (e.g., PET, cotton, wool, PAN, CV, etc. ), 15,18,27,[31][32][33][34] which of course contain a broad assortment of potential adsorption sites (e.g., -OH, -NH 2 , -COOH, -SO 3 H, -OCOCH 3 , etc.) with which sorbed dye molecules can interact and eventually become adsorbed onto.…”

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. The precise reasons why very high temperatures in the region of 130oC promote the uptake of disperse dyes on poly(ethylene terephthalate) fibres from aqueous dyebaths have not been satisfactorily resolved, nor has the exact mechanism by which carriers promote dye uptake at lower temperatures in the region of 98oC been adequately established. In this part of the paper, a detailed review and analysis is presented of the various concepts and theories that have been proposed to account for the promotional effects of temperature and carriers on disperse dye uptake, from the viewpoint of both the thermodynamic and kinetic aspects of the adsorption of the dyes on poly(ethylene terephthalate) and other types of fibre.This article is protected by copyright.

“…Despite the many differences between cotton, PA 66 and PET fibres, it is widely assumed that the mechanism of disperse dye adsorption described earlier in the case of PET fibres 2 applies to each of these three types of textile fibre (eg, [4][5][6][7][8] ). This all-encompassing mechanistic assumption therefore tacitly presupposes that the manner by which disperse dyes interact with PET, cotton and PA 66 substrates is identical, which implies that the particular physico-chemical characteristics responsible for disperse dye-fibre substantivity and the forces of interaction that govern both the diffusivity of the dyes and their adsorption within the different types of fibre, are also identical.…”

To further investigate the contribution of polymer relaxation times to the mechanism of disperse dye adsorption on poly(ethylene terephthalate) fibres, the temperature‐dependent uptake of Teratop Yellow HL‐G 150% on both cotton and polyamide 66 fabrics at temperatures between 30 and 130°C was compared with that on poly(ethylene terephthalate) fabric. Although uptake of the commercial grade dye on polyester fabric is governed by the thermally regulated, broad glass transition of the water‐saturated poly(ethylene terephthalate) substrate, as this was not observed for either cotton or nylon 66 fabrics, the respective cellulose or polyamide 66 polymer glass transition does not present a major thermal impediment to dye uptake over the wide range of dyeing temperatures used. This is because the onset and end‐set temperatures of the glass transition of the water‐plasticised poly(ethylene terephthalate) material reside within the range of dyeing temperatures employed, whereas those of the water‐plasticised cotton and polyamide materials occur below the lowest dyeing temperature examined (30°C). The thermal dependency of disperse dye solubility also likely makes a meaningful contribution to the temperature‐dependent dye uptake observed for each type of fibre.

I N present work, different natural fabrics (cotton, wool and silk)were printed via pomegranate peel dye. The dye solution subjected to ultrasonic to reach the nano size.Two techniques of mordanting were used, (pre-mordanting and simultaneous mordanting);substrateswere mordanted prior to printing process using two ecofriendly mordants separately: Alum and tannic acid, other substrates were printed via paste incorporated with mordant for comparison. Pomegranate peel natural dye was studied to clarify the impact of nature of nano-size color particles on size, shape, and particle distribution of the natural dye with comparative studies of the K/S and over all fastness properties of printed samples.Results showed that the K/S values of nano samples are higher than original samples, irrespective of the nature of the fabric used and /or the concentration of the coloring matter. Nano-pomegranate peel dye could be used successfully instead of the original dye incorporated with Alum mordant irrespective of the fabric used. In addition,pre-mordanting technique acquired the higher K/S values than the simultaneous mordanting technique.There is a tendency of improvement of the perspiration fastness while keeping the washing and rubbing fastness unaltered after miniaturization of the pomegranate dye.
