Specification :

" SERACTIVE HE TYPE reactive dyes contain a monochlorotriazine reactive group, suitable for
80 hot dyeing. They have very good diffusion and migration at high temperature, and so have excellent penetration and levelness especially for critical articles such as viscose, mercerized cotton etc. However, they are not so easy to wash off due to their high substantivity. They have high fixation rate, good light and chlorinated water fastness. This series of dyes is very suitable for high-strength deep shades.
