ABSTRACT:
As a means for applying a random mottled or hammered appearance to a textile material, this invention provides a process which comprises the steps of: (a) applying to the textile material an aqueous solution having a water insoluble dye dispersed therein and an ionic component in the form of a dispersant in sufficient quantities to disperse the dye; (b) subsequently applying to the textile material an aqueous flocculent solution including a counter-ionic component, thereby electro-chemically reacting with the ionic dispersant such that the dye is precipitated from solution in non-uniform concentrations; and (c) fixing the dye to the textile material, preferably by heat. A textile material dyed according to the process is also provided.
