Abstract
The invention provides a method for increasing the color density of a dyed fabric material of, especially, a synthetic fiber as well as the fastness of the color to rubbing and washing. The inventive method comprising (a) pretreating the dyed fabric material with an organopolysiloxane which is an amino-modified organopolysiloxane or a dimethylpolysiloxane, and then (b) exposing the thus pretreated dyed fabric material to low temperature plasma of an inorganic gas under a reduced pressure. The inorganic gas is preferably oxygen or a gaseous mixture containing at least 10% by volume of oxygen. The color-deepening effect is particularly remarkable when the color of the dyed fabric material is black to impart increased graveness and vividness of the color.
