Abstract:
Ultrasonication emerges as a promising technique to utilize in the dyeing processes in
textile industries to minimize energy consumption. The efficacy of ultrasonication in the
dyeing process has been demonstrated in this research, particularly in Lycra and Tricot
fabrics, where achieving optimal temperature and contact time conditions can result in
reduced energy consumption, cost-effectiveness, and improved product dyeing quality.
The factorial experimental design and analysis technique was utilized to experimentally
evaluate the synergistic effects of the major process parameters. The product dyeing
quality was chosen as the dependent variable and was quantitatively determined by a
specific spectrophotometer. Through a comprehensive ANOVA study on the experimental
results, it has been scientifically demonstrated that ultrasonication, combined with
contact time and temperature of the dyeing bath, significantly impacts the ultimate
product dyeing quality. Based on the findings, it is imperative to establish that optimal
dyeing results for the intertwined Lycra and Tricot fabrics can be achieved by employing
ultrasonication at temperatures ranging from 60°C to 70°C, with contact times exceeding
45 minutes in comparison to the conventional dyeing process carried out at 98°C and 1
hour respectively. These findings highlight the efficacy of ultrasonication in enhancing the
dyeing process for both Lycra and Tricot. Ultrasonication demonstrated a substantial
improvement over previous results obtained without ultrasonication, resulting in a
noteworthy reduction of 39% in operating temperature and 25% in contact time. This
underlines the synergistic effects of ultrasonication and process parameters, wherein
ultrasonication acts as a catalyst, enhancing dye penetration and fixation within the fabric
structure. The integration of ultrasonication in the dyeing process offers significant
advantages, including reduced energy consumption, improved process efficiency, and
enhanced fabric quality, making it a promising technique for achieving sustainable dyeing
goals.
