Optimisation of Novel Amine Shrinkproofing and Dye-assist Treatments on Wool

A study of shrinkproofing and dye-assist treatments has been performed using ethanolamine as the reactive agent and isopropanol/water mixture as the treatment medium. The three variables studied were percentage of isopropanol in the treatment bath, ethanolamine concentration and temperature. These were optimised in terms of shrinkage prevention, dye-assist effect, weight loss and yellowing results obtained
