Halocromic dyes change theis colour with pH. There is a problem focused on the determination of the
concentration for halochromic dyes attached to a fibre. This article studies the influence of
halochromism on the absorbance measurement protocol of polyamide dyeing wastewater with Rose
Bengal. For this purpose, two dyes are prepared at neutral and acid pH, and their concentrations are to
be determined by absorbances of exhaustion and washing wastewaters. In addition, in order to check
their fastness, a washing test is carried out on dyed fabrics and on fabrics post treated with a fixer.
