“…However, other than enhanced surface hydrophilicity and interfacial adhesion in paraaramid composites, limited improvement has been reported in dyeing para-aramids (Sun et al, 2014). Azam et al (2019) had success in dyeing meta-aramid fibers with disperse dye by increasing the dyeing temperature and concentration of the swelling agent. Vu and Michielsen (2019) explored dyeing meta-aramid fibers with basic dyes at lower temperatures by grafting poly(acrylic acid) onto the surface of the meta-aramid fiber, creating readily available bonding sites for a basic dye.…”

High-performance para-aramid fibers offer a number of uses as strong, lightweight materials for protective vests, helmets, tires, and other applications. The chemically inert nature of the fibers makes them difficult to dye or durably print by conventional dyeing techniques for textiles, and solution dyeing during production of the fibers can limit the color of para-aramid fabrics to the color of the spun yarn prior to weaving or knitting and thereby limit the practical applications of these textiles as protective outerwear. This study presents a new method developed to improve the dyeing of woven para-aramid fabrics with a disperse dye. Specifically, sequential experimentation proves the beneficial effects of first soaking para-aramid fabrics in soybean oil followed by surface treatment with atmospheric nonthermal plasma and using glycerol as the dispersant and sodium chloride as an electrolyte without the addition of other auxiliary chemicals. Under the optimized treatment conditions of this study, the color strength (K/S value) of dyed para-aramid fabrics increased to 3.89 from 0.35 of the untreated samples as determined from spectral analysis of the sample reflectance in the visible range. Fourier transform infrared spectroscopy analysis revealed that the high content of unsaturated fatty acids in soybean oil and their interaction with reactive species in the ambient nonthermal plasma were the primary factors for improving the color strength of the dyed para-aramid fabrics.

“…Due to their characteristics, disperse dyes have different adsorption and diffusion capacities on different types of fibers. 49,50 In this paper, only ordinary woven polyester fabric was selected for dyeing experiments with compound dyes, which had limitations in the diversity of dye-bearing fabrics. Thus the feasibility and applicability of this calculation and prediction method applied to other fibers need to be further explored in the future.…”

Black is a special color that has achromatic characteristics and shows a sought-after sense of mystery. Most of the black disperse dyes are compounded with multiple dyes. In this paper, a quantum chemical calculation method based on density functional theory and time-dependent density functional theory was proposed to predict the components’ proportion of black disperse dye. C.I. disperse blue 291, C.I. disperse red 73, and C.I. disperse orange 61 were selected as components of this black dye. After structure optimization and vertical excitation calculation of many other disperse dyes, and experimental tests of the maximum absorption wavelength of ultraviolet-visible, an equation between the calculated values and the experimental values was obtained by multiple regression analysis. This equation was used to correct the calculated spectrum of each target component. Then the combined spectrum of the three dyes was used to establish the prediction equation set, and the mixing proportion was calculated from this. Through verification of dyeing experiments and related tests, the new method in this study has a good result on the components’ proportion prediction of black disperse dye.

“…As one of the indispensable materials for textile printing and dyeing processing, there are dyes that makes textiles obtain colour. 1,2 Relative colour strength (RCS) of dye is known as an indicator that is capable of evaluating the dyeing behaviours, it has been widely used for such as vegetable dyes, modified dyes, and the development of other new dye products, 3,4 dyeing properties of fibre and fabric, 5,6 the study on dyeing and finishing process, 7,8 and so on. Moreover, in actual production and processing, even for the same type of dye, due to the different purchase batches, it is usually necessary to use the RCS to test the distinctions of different batches of dyes.…”

Relative colour strength (RCS) of dye plays an important role in the production, the evaluation and the application of dyes. There are different standards on the determination of it, their principles are all related to colour depth. However, the standard methods have some limitations. For this purpose, this study proposed a new method for the RCS based on the new colour depth formula Yangn, which included three methods named colour strength value (CSV1, CSV2 and CSV3). Part I in this study was to investigate the application effect of Yangn on the RCS of different disperse dyes with approximate hues. According to the experimental results of E-type and SE-type disperse dyes, the new method showed its advantages. Firstly, compared with AATCC EP-6, the results of the new method were more consistent. Secondly, under different dyeing concentrations, the RCS values of the new method were relatively consistent, with average coefficient values (CVs) being less than 5%, especially for CSV3 with only 3.59%; while all the average CVs of AATCC EP-6 were greater than 6%. For the calculation of RCS of different types of dyes with approximate hue, the new method presented more accurate results.
