Effect of ethylene glycol and its derivatives on the aggregation properties of reactive Orange 13 dye aqueous solution

Abstract

The interaction between Orange 13 dye and ethylene glycol and its derivatives was determined by the dispersion force.

Effects of alkanolamine solvents on the aggregation states of reactive dyes in concentrated solutions and the properties of the solutions

“…Hydrogen bonds and hydrophobic forces in the hydrophobic parts of dye molecules lead to different degrees of dye aggregation. 38 It has been pointed out that the hydration layer around the benzene ring consists of 24 water molecules. 24 …”

“…Fluorescence spectroscopy is also an important measure to analyze the aggregation state of dyes. 36,37 The increasing degree of dye aggregation could reduce the intensity of uorescence. 38 As shown in Fig.…”

“…36,37 The increasing degree of dye aggregation could reduce the intensity of uorescence. 38 As shown in Fig. 6a and b, for R-218, the uorescence intensity gradually increased with the increase in the concentration of DEA/TEA in dye solutions.…”

“…Hydrogen bonds and hydrophobic forces in the hydrophobic parts of dye molecules lead to different degrees of dye aggregation. 38 It has been pointed out that the hydration layer around the benzene ring consists of 24 water molecules. 24 The interactions between the dyes and the solvents were also studied by taking the most signicant combination (R-218 in 5% DEA solution) as an example.…”

Eco-Friendly Pretreatment to the Coloration Enhancement of Reactive Dye Digital Inkjet Printing on Wool Fabrics

“…It has unique superiorities such as low cost, high precision, and celerity compared with traditional printing which was limited to produce high-quality and personalized products. − Among all kinds of dye-based inks, reactive dye ink accounts for an increasing proportion. It has the advantages of bright color, comprehensive color range, good level dyeing, and high fastness, and it can form covalent bonds with both cotton and wool fabrics. − Plenty of research studies reported that reactive dye inkjet printing has been successfully used for cotton fabrics as it shows cotton’s characteristics of reproducibility, good dyeability, and low cost. , However, there are few articles reporting about its application in wool fabrics.…”
