Membrane technology:Reactive dyes and cleaner production

摘要

Reactive dyes first appeared commercially in 1956,after their invention in 1954 by Rattee and Stephens at the ICI Dyestuffs Division site in Manchester,UK.The dyes contain a reactive group,either a haloheterocycle or an activated double bond,that,when applied to a fibre in an alkaline dye bath,forms a chemical bond with a hydroxyl group on the cellulosic fibre.
