Teinture -- Fibres textiles synthétiquesIndex. décimale : 667.2 Colorants et pigments Résumé : When textile substrates biodegrade in landfills, the fate of textile colorants is unknown, and potentially poses an ecotoxic threat. In this study, we developed a systematic analytical method to evaluate the biodegradation of reactive dyes, the most common class of dye applied to cotton fabrics. The cotton fabrics were dyed with CI Reactive Blue 19 and biodegraded in soil in a laboratory-controlled environment over intervals of 45 and 90 days. A dye isolation method using a low concentration of alkali (0.15% sodium hydroxide) was developed and applied (80°C for 1 hour) to isolate intact and degraded dye from the fabric samples. To quantify the intact dye isolated from the fabric samples, a quantification method was then developed using liquid chromatography-photodiode array detection. The quantification method provided excellent linearity (R2 = 0.9997 ± 0.0002), accuracy (% error = -2% ± 4), precision (% coefficient of variation = 2% ± 4) and sensitivity (lower limit of quantification = 0.4 ± 0.2 µg/mL) for concentrations ranging from 1 to 50 µg/mL. After validation, the method was applied and showed a reduction of dye in biodegraded samples (after 45 and 90 days) compared with undegraded control samples (0 days). To characterise the isolated dye degradation product, quadrupole time-of-flight tandem mass spectrometry was utilised. Analysis showed that the degradation product was formed by losing a -SO3- group from the intact hydrolysed form of the dye, creating a more hydrophobic degradation product compared with the intact hydrolysed form of dye.

Teinture -- Fibres textilesIndex. décimale : 667.3 Teinture et impression des tissus Résumé : Landfills are becoming the most common way to dispose textiles. The presence of different types of dyes and finishes on textiles fabrics can become an important source of pollution during the degradation process, due to the fact that these chemicals can leach to the soil. The biodegradation of dyes from dyed fabrics is not fully understood, and what can leach into the soil can be more toxic. In this study, cotton fabrics were dyed with CI Reactive Blue 19 (RB19) and biodegraded in soil in a laboratory-controlled environment for a 90-day time interval by using the ASTM D 5988-18 method. A modified QuEChERS (quick, easy, cheap, effective, rugged, and safe) extraction method, in combination with liquid chromatography-mass spectrometry (LC-MS) analysis, was applied to soil containing RB19 after the degradation process. An unknown degradation product, with a mass-to-charge ratio (m/z) of 393, found in the soil was characterised and confirmed, via high-resolution MS and tandem MS, to be CI Acid Blue 25 (AB25). To quantify the confirmed unknown product extracted from the degraded soil sample, a quantitation method was developed using high-performance liquid chromatography-diode array detector-mass spectrometry (HPLC-DAD-MS). The quantitation method provided excellent linearity (R2 = 0.9990 ± 0.0006), accuracy (mean percentage error = 5.17 ± 1.88), precision (mean percentage coefficient of variation = 4.73 ± 4.16), and sensitivity (lower limit of quantitation = 1.29 ± 0.47 µg/mL) for nine concentrations ranging from 0.5 to 40 µg/mL.

Teinture -- Fibres textilesIndex. décimale : 667.3 Teinture et impression des tissus Résumé : Cationised cotton allows the dyeing of cotton fabrics without salt and up to 100% anionic dye utilisation. The employment of cationised cotton in the dyeing of high depths of shades with reactive dyes holds marked potential for sustainable improvements through less dye consumption, decreased water usage, and zero salt utilisation, all while obtaining shade depths darker than possible with conventional reactive dyeings. This work builds upon previous work in obtaining ultradeep dyeings of cotton utilising cationised and mercerised cotton by investigating the effects of liquor ratio in dyeing and amount of dye applied. Surprisingly, for mercerised only cotton fabric, it was found that nearly equivalent depths of shade, as indicated by L*, were obtained, irrespective of the liquor ratio and the amount of CI Reactive Black 5 applied from 7% to 10% owf. However, the strengths of the dyeings, indicated by the K/S sum, show slight increases with increasing amounts of dye, but not when the liquor ratio is lowered. Similarly, for mercerised-cationised cotton, the liquor ratio had a negligible effect on the depth of shade obtained, but increasing the amount of CI Reactive Black 5 resulted in an increase in shade depth and colour strength. Very deep shades with high colour strength were obtained with mercerised-cationised cotton that were not obtainable with uncationised cotton, even at a very low liquor ratio and with a drastic increase in the amount of CI Reactive Black 5.

Teinture -- Fibres textilesIndex. décimale : 667.3 Teinture et impression des tissus Résumé : Cationisation allows cotton to be dyed with anionic dyestuffs (including anionic pigment dispersions) without the need for salt, and with decreased usage of dye, water, and energy. Appropriate cationisation levels play a part in dyeing properties such as fabric levelness, in fastness properties such as lightfastness, and in the overall cost of the cationisation treatment. The objective of this work is to assess whether it is possible simultaneously to predict a dye recipe and cationisation treatment level for cotton to yield a colourless or nearly colourless dyebath at the completion of the dyeing to match the shade of conventional fibre reactive dyeing of cotton. It has been shown that it is possible to model a cold pad batch cationisation process, relate the colour yield data and cationisation level for individual dyes, and finally predict a dyeing recipe and the required corresponding cationisation treatment to match the shade of conventional fibre reactive dyeing of cotton. The predicted dye recipe and cationisation amount yield colourless or nearly colourless dyebaths at the conclusion of the dyeing process.

Spectrométrie de masseIndex. décimale : 667.2 Colorants et pigments Résumé : The separation and identification of colourants from aqueous matrices could potentially benefit the coloration industry. In this work, we report a new method that combines hydrophilic interaction liquid chromatography (HILIC) and high-resolution mass spectrometry (HRMS) for reactive dye separation and identification without employing ion-pairing agents. The conditions outlined allowed the successful separation of a mixture of four commercial reactive dyes in an aqueous solution, which consisted of CI Reactive Black 5, CI Reactive Orange 35, CI Reactive Blue 49 and CI Reactive Red 31. To further demonstrate the feasibility of this new method, we conducted deeper research into the analysis of CI Reactive Red 31 and its hydrolysis products. Based on the high efficiency of HILIC for polar compounds, and its combination with HRMS, we were able to identify several isomers of CI Reactive Red 31 and its derivatives, which were further characterised by tandem mass spectrometry. This method could potentially benefit chemical evaluations in dye applications, including synthetic processes, because it provides reliable results and simplified operation conditions compared with common traditional high-performance liquid chromatography methods.
