摘要

An eco-friendly approach to dyeing high-performance polyetherimide (PEI) fibers is presented to avoid the toxic effects of diffusion accelerator (carriers) and disperse dyes used in the conventional high-temperature dyeing processes. Natural oils are investigated as bio-based carriers for natural turmeric dying of PEI fabric with microwave-assisted dyeing technology. This study evaluated 21 different natural oils as carriers to optimize the turmeric dyeing performance of PEI fabrics. A systematic evaluation of 21 natural oils identified optimal carriers, with vanilla oil (6 g/L) demonstrating the highest color strength (K/S) and minimal tensile loss. Sage and lavender oils also showed favorable performance at specific concentrations. Statistical analysis, color fastness evaluation, and advanced characterization (FTIR, SEM) validated the efficacy of these carriers. This study demonstrates that essential oil types can be used as natural carriers in the dyeing processes of high-performance fibers, and at the same time, it enables the adoption of renewable resources and environmentally friendly processes in material innovation, contributing to the advancement of sustainable textile dyeing applications. To balance tensile strength and color performance, this study also emphasizes how important it is to choose and optimize essential oil types and concentrations. When taken as a whole, these findings support the development of environmentally friendly textile dyeing techniques and the encouraging possibilities of natural-dyed PEI textiles for high-performance uses in fashion, interior design, automotive, and aerospace industries.
