Abstract

Abstract This invention relates to fabric treatments by which cotton and cellulosic blended fabrics can be provided with wrinkle resistance (smooth dry performance) and color at the same time. In particular, it provides a means by which cellulosic fabrics can be dyed with basic dyestuffs. In addition to a conventional means by which the entire fabric can be dyed with a basic dye, variations are achieved in which one side of the fabric is dyed one color and the other side of the fabric is dyed a second color. The color on the reverse side can be provided by means of either basic dyes or regular cotton dyes. The technique has also been extended for the printing of fabrics.
