The effect of dye dispersion preparation prior to dyeing on the dyeing ability of the disperse dye on polyester fabric was studied. The influence of sodium laurylsulphate (SLS) concentrations and the homogenization process was determined. The optimum SLS concentration for dyeing observed in this study was 0.01 M. The color yield of the dye passing through the homogenization process on polyester fabric was higher than that from the conventional dye preparation. Homogenization was also found to enhance disperse dyeability at a lower dyeing temperature. It infers that the dyeing process could be done at a lower temperature. The dyeing temperature could be as low as 110oC in the presence of homogenization. The effect of homogenization on the dyeability at different dyeing times was also examined.

A novel functional disperse dye doped with graphene oxide for antistatic properties of polyester fabric was achieved, which means that the dyeing and antistatic finishing can be simultaneously obtained by a one-bath method. Functional dyes were used to dye polyester fabric by a high-temperature, high-pressure dyeing method. The surface microscopic morphology of the dyed polyester fabric, and the dispersion properties of the disperse dye, graphene oxide, and the functional disperse dye, were characterized by scanning electron microscopy. The effects of the dyeing temperature on the particle sizes of three dyeing liquors were explored; this revealed that the temperature of the dyeing process had no effect on particle size. The dosage and reduction time of graphene oxide were investigated. The surface electrical resistance of the dyed fabric, 9.8 × 106 Ω, obtained at a condition of 2% (o.m.f) graphene oxide with a reduction time of 30 min, achieved A-grade antistatic standard. Furthermore, the rubbing and washing fastness of the treated fabric were 4- and 4 ∼ 5 grades, respectively. This preparation of the functional disperse dye provides a possibility in one-bath dyeing and antistatic finishing of polyester fabric.

Supercritical CO2 fluid dyeing, a new type of anhydrous dyeing technology, has the advantage of high uptake rate, short dyeing process, recycling of dyes and CO2, and zero discharge. This study investigated a dyeing technique of loose fibers using supercritical CO2 as solvent to replace water. Based on the existing characteristics of the self-developed supercritical CO2 dyeing equipment, a special dyeing frame of loose fibers was designed. Using the dyeing frame and inner and outer dyeing processes, polyester fibers were dyed with disperse red 153# maternal dyes at temperatures of 80–140?, pressures of 17–29MPa and time of 20–80min, respectively. The experimental results revealed that the dyeing performance of fibers was good on the dyeing frame, as well as with a favorably increased temperature, pressure and time. Dyeing temperature had a strong influence on the color yield. The dyeing results were compared with those of polyester fibers dyed with disperse red 153# dyes. With the special dyeing frame of loose fibers, color fastness to washing and artificial light was generally similar to conventional aqueous medium methods.

The aim of current work is to evaluate the dyeing performance of newly introduced disperse dye to improve its dyeing behavior onto polyester fabric using microwave radiation. Microwave heating has promisingly improved the disperse dyeing of polyester fabrics. Disperse Yellow 211 (DY 211) has been used to dye the polyester fabric under the influence of microwave treatment. Both the fabric and dye solution, were treated with the microwaves for 1- 6 min. Different dyeing parameters such as temperature, time, dispersant and dye bath volume were also optimized and ISO standard methods for colorfastness were employed to rate the influence of microwave and ultraviolet treatment on disperse dyeing. It is found that microwave treated polyester (RP, 6 min), has given good color strength and darker shades upon dyeing at 90°C for 40 min. in the presence of 2 g/100ml of dispersant using 70 mL of irradiated dye solution (RS, 6 min) of pH 8. Similarly using dye bath of pH 11, microwave treated polyester (RP, 6 min.) has given good color strength and darker shades upon dyeing at 70°C for 35 min.in the presence of 1 g/100ml of dispersant. using 50 mL of irradiated dye solution (RS). ISO standards for fastness to light, washing and rubbing revealed that good to excellent ratings have been obtained from different shades dyed at optimal condition. It is inferred that Microwave treatment has not only reduced the dyeing conditions but also improved the color characteristics of dyed polyester fabric.

In this paper the influence of the formic and oxalic acids, as substances for dyebath pH adjusting, on the dyeability of polyester fabric dyed with disperse dye Disperse Yellow 23 was examined. The polyester undyed knitwear samples were dyed in baths containing the acids under the same dyeing conditions. Color differences of the samples were assessed using the reflectiometry technique and expressed in terms of CIELcoordinates. The influence of the tested acids on the surface structure of dyed polyester fibers was examined using the scanning electron microscopy (SEM). It was found that the differences in obtained dyeabilities, in the presence of both formic and oxalic acid, are acceptable according to both M&S 83A and CMC (2:1) standards which was not the case with acetic acid. Therefore, acetic acid can be replaced with either formic or oxalic acid as substances for dyebath pH adjusting in the dyeing process described in this paper. SEM micrographs showed small differences in the surface structure of dyed fibers, as well as differences in the shape of undyed samples? reflectance curves in presence of the acids. Since all of the color differences were quite small, it can be concluded that the influence of formic and oxalic acids on the polyester knitwear dyeability is not significantly different than that of acetic acid.

Polyester Dyeing

In this paper, modelling of dyeing, i.e. adsorptive behaviour of disperse dyes on polyester fibres (dyeing), under the influence of ultrasound has been considered with the aim of getting the data about mechanisms of binding the dyes and defining the conditions of dyeing process of this synthetic fibres along with additional energy source without the use of carriers, compounds that increase permeability of the fibres and help dyeing. Dyeing - adsorption is conducted under different conditions, and the concentration of dyes, mass of the substrate, recipes and time of dyeing were being varied. It has been established that ultrasound allows dyeing without carriers and the efficiency of dyeing depends on the time of contact, initial concentration of the dye and the amount of absorbent - material. There is the continuity of growth of the amount of bound dye to the mass of the absorbent. Characteristic graphs, obtained from Langmuir isotherm, have confirmed that this model ensures precise description of polyester dyeing by disperse dye. Kinetic of dyeing has been remarkably interpreted by pseudo second-order in regards to the high functionality.

The level dyeing index (LDI) is a measure of dye performance influenced by the dye migration process, ensuring the maximum uniformity of dye redistribution onto the fabric surface. The current study evaluates the level dyeing performance on polyester according to the energy level (low and high) and chemical classes (azo and anthraquinone based) of the three disperse dyes studied. The best levelness was obtained using C.I. Disperse Red 73 (an azo-based, low-energy level disperse dye), which exhibited the highest migration index (MI%) value. LDI results were obtained from the ratio of the exhaustion at the critical dyeing temperature (ECDT% and the final exhaustion Ef%), and the migration index (MI%). Each dye's LDI can be used to determine the compatibility of disperse dyes for combination dyeing.

This paper reports on the application of natural dyes on polyester fabric. Melastoma malabathricum l. was extracted using conventional method of boiling for an hour. Plain lightweight polyester fabric was treated with sodium hydroxide as an alkaline treatment and Chitosan prior to dyeing in an attempt to increase the dye uptake. The dye extract of Melastoma malabathricum l. was applied on the polyester fabric at 85°C for an hour by exhaustion dyeing and 40 minutes for ultrasound dyeing. The colors of the dyed fabrics were measured using colour spectrophotometer and evaluated for washfastness. Ultrasound dyeing gave deeper colour shades to the fabric even though dyeing was conducted at lower temperature for 40 minutes. The alkaline treated fabrics dyed using ultrasound gave lower value of L* which indicate higher dye uptake and darker colour. The ratings for colourfastness to washing were between 4/5 to 5.
