通过测定染料-棉键在98 ℃缓冲水溶液中的水解动力学，研究了各种双功能染料（商品名为Sumifix Supra染料）的染料-纤维键稳定性。通常发现稳定性略高于可比的单官能活性染料的稳定性。然而，明显更好的是双官能染料的固定产率。非商业溴氨酸基双功能染料的吸收率非常低的原因进行了讨论。
The dye-fibre bond stabilities of various bifunctional dyes (commercially known as Sumifix Supra dyes) have been investigated by measuring the kinetics of dye-cotton bond hydrolysis in aqueous buffer solution at 98dC. The stabilities are generally found to be somewhat higher than those of comparable monofunctional reactive dyes. Significantly better, however, is the fixation yield of the bifunctional dyes. Reasons for a very low uptake of a non-commercial bromamine acid-based bifunctional dye are discussed.
