Structural alteration of the pretreated fibres was reflected by thermogravimetry and Fourier transform infrared spectroscopy, indicating more H-bonds, lower crystallinity, and slightly lower thermal stability. The change in structure showed that 2-phenoxyethanol combined with the fibre macromolecules and resulted in swelling of the fibre. Creation of a biphasic system through the addition of 2-phenoxyethanol to the dyeing solution resulted in the cationic dye being partitioned more towards the 2-phenoxyethanol-rich phase than the aqueous phase. The cross-sections of the dyed fibre suggested that the meta-aramid fibre could be dyed more thoroughly with an appropriate concentration of 2-phenoxyethanol. The colour value of aramid fabric was tested by varying the concentration of 2-phenoxyethanol and the temperature of pretreatment, indicating a dramatic improvement in dyeing performance to aramid after 2-phenoxyethanol pretreatment. 2-Phenoxyethanol pretreatment and low-temperature dyeing can overcome the problems of chemical and energy waste while producing a satisfying colour.

Teinture -- Fibres textiles synthétiquesIndex. décimale : 667.3 Teinture et impression des tissus Résumé : In this study, 2-phenoxyethanol was used as a carrier to realise the bright-colour dyeing of aramid fibre. Fourier transform infrared, X-ray diffraction, and thermal analyses were used to characterise the modification of 2-phenoxyethanol on the aramid fibre structure. The dyeing performance, including the K/S value and the dye uptake, was tested by varying the concentration of 2-phenoxyethanol and related experimental parameters. Structural analysis suggests strengthened H-bonds, lower crystallinity, and slightly lower thermal stability after 2-phenoxyethanol treatment, which can be explained by the swelling effect of 2-phenoxyethanol, enlarging the amorphous structure through the reassembly of hydroxyl bonding to the aramid fibre. The dyeing performance can be improved by increasing the dyeing time, the temperature, and the concentration of sodium nitrate under slightly acidic condition. Colour fastness tests showed that 2-phenoxyethanol treatment does not affect the rubbing fastness but lowers the wash fastness slightly. Dyeing of aramid is crucial under special environmental conditions in which the products must withstand a harsh environment while retaining a bright colour.
