Abstract
Purpose
The purpose of this paper is to discuss applied statistical design of experiment (DOE) to optimize the process of dyeing in natural fiber through the multidisciplinary photoacoustic technique.
Design/methodology/approach
First, the spectroscopy analysis of the dyestuffs was carried out based on the 23 factorial design. Second, the DOE was utilized to find which process variables were most significant in the absorption band’s intensity of the dye. Finally, the impregnation optimization of fiber was carried out based on response surface methodology.
Findings
The results showed that the dyeing process is more efficient for samples with lower level of dye concentration and dyeing procedure time. The statistical study of the effect of each preparation factor suggested that the composition of the colors has a pronounced influence in the fiber dyeing.
Originality/value
Using the DOE and photoacoustic response in the present work was clearly found and proposes a less expensive dyeing process and that reduces the harmful impact to environment.
