Toward improved performance of reactive dyeing on cotton fabric using process sensitivity analysis

Abstract

PurposeThe conventional textile dyeing process requires various operational characteristics, and determining the most reliable factor in dyeing performance has always been a challenge for the textile industry. Thus, the present paper aimed to evaluate the process sensitivity of C. I. Reactive Blue 194 dyeing of cotton fabric using a statistical technique.Design/methodology/approach An L27 orthogonal array-based Taguchi's methodology was used with six parameters and three levels of each parameter. The signal-to-noise (S/N) ratio and analysis of variance were studied using total fixation efficiency (T%) as the response of the process sensitivity.Findings Results showed that dyebath pH was the most influential factor on the process and total fixation efficiency (p-value = 0.00 and contribution percentage 45.03%), followed by dye-fixing temperature, dye mass, electrolyte concentration, dye-fixing time and material to liquor ratio.Originality/value Overall this study provides a foundation for the determination of dyeing process sensitivity that will be useful in textile industries toward further development.

Sustainable dyeing of ramie fiber with ternary reactive dye mixtures in liquid ammonia

“…During the drying at 100 °C, the residual liquid ammonia was evaporated, and the vinyl sulfone sulfate was transferred to vinyl sulfone group. 33 Subsequently, some of the reactive dyes were chemically fixed with the ramie fiber by covalent bonding, 43 as shown in Fig. 4 .…”

Sustainable traditional grass cloth fiber dyeing using the Taguchi L16 (4^4) orthogonal design

“…Although the F% (78.77%) was not the highest value (80.44%), its highest E% (61.44%) made a huge contribution to the T% value. Therefore, the influence of dyeing factors on T% was complicated 20 , and it is worth closely analyzing with the Taguchi analysis method.…”

“…With the regression equation, it is possible to correctly compute and compare projected values based on experimental circumstances 20 . For the T% of reactive dye, the fitted plots of expected vs experimental responses are shown in Fig.…”

“…In reactive dyeing, the final color shade of the dyed substance is decided by the total dye efficiency (T%), which is based on the dye exhaustion percentage (E%) and dye fixation rate (F%) 19 . In general, dyeing conditions are influenced by various factors 20 such as salt concentration, fixation time, fixation temperature, and pH of the dyebath, and it is necessary to develop a systematic approach to the planning, implementation, and evaluation of the process to generate the best results.…”

Sustainable and eco-friendly dyeing of traditional grass cloth with a reactive dye in palm oil medium

“…A fitted plot assessment delivers the regression equation, which allows accurate computation and comparison of predicted values depending on experimental conditions. 49,50 Fig. 10 displays the fitted graph of predicted versus experimental responses for the K / S values of the dyed samples.…”
