Dyeing Soybean Protein Fiber with Reactive Disperse Dye By Supercritical Carbon Dioxide

By contrasting the dye uptake in Supercritical Carbon Dioxide dyeing with which was at the same condition in aqueous bath dyeing,we get gooder the dye uptake in Supercritical Carbon Dioxide dyeing.And, through Friction fastness, Soaping fastness, Rubbing fastness of the dye uptake was tested, the better dyeing results are got in this experiments. In a word, such research has a certain practical significance on the development of soybean protein fiber dyeing and the field expansion of the supercritical Carbon Dioxide fluid dyeing, also lays a foundation for the future research.
