3 principle
The reactive dyes are stained on cotton fibers, and as the dyeing process progresses, various hydrolysates are gradually produced. Determination of the dyeing process by liquid chromatography
The peak area of the hydrolyzate is calculated by comparing the peak area of the effective dyes to which the dye is dyed and by a series of conversion corrections.
The sum of the hydrolysis rates of the product. And then the dyeing time for the abscissa, the total hydrolysis rate as the ordinate, drawing hydrolysis rate curve. To hydrolysis rate
The curve shows the rate of hydrolysis of the reactive dye during the dyeing process.
