What is it about?
To improve the fiber dyeing process analyzing commercial colourant absorption.

Why is it important?
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.
Perspectives
The Photoacoustic Spectroscopy is a nondestructive power tool for analyze the dye impregnation once the entirely knowledge of the chemical structure of the dye is not even necessary to identify it in the fiber.
