ABSTRACT:
A coloration method for textiles using chemically formed gels is disclosed. The method provides considerable freedom for making color designs and precise pattern prints, and can be used with conventional dyeing and printing equipment. In one embodiment of this invention, gelled regions are formed by separately applying a gelable composition containing alginic acid or an alginic acid derivative and a gelling agent composition to a textile material, and then over-dyeing the material, the gelled regions serving as dye resist regions. In another embodiment of this invention, lateral ink spread typically occurring as a result of printing or imparting patterning to the textile material is reduced by incorporating a dye into either the gelable composition, the gelling agent composition or both compositions, such that when one of the compositions is applied over the other composition, gelled print or pattern regions are formed, lateral spreading of the compositions is inhibited and, accordingly, excellent print or pattern definition is achieved.
