Abstract
A dye composition and a dyeing method for an elastic fabric are provided. The dyeing method includes: (a) providing an elastic fabric which includes an elastic fiber; and (b) immersing the elastic fabric in a dye composition. The dye composition includes an ion modifier and a dye. The elastic fiber of the elastic fabric has a first ion by contacting the ion modifier, and the first ion has a first charge; the dye has a second ion, and the second ion has a second charge opposite to the first charge. The first ion of the elastic fiber and the second ion of the dye together form an iconic bonding.

A dyeing method for an elastic fabric, comprising:
- (a) providing an elastic fabric including an elastic fiber;
- and
- (b) immersing the elastic fabric in a dye composition, the dye composition including an ion modifier and a dye, so that the elastic fiber of the elastic fabric contacts with the ion modifier and the dye;
- wherein, the elastic fiber has a first charge by contacting the ion modifier, the first charge has a first ion, the dye has a second ion, the second ion has a second charge opposite to the first charge, and the first charge of the elastic fiber and the second ion of the dye together form an ionic bonding to obtain a dyed elastic fabric.
A dye composition for an elastic fabric, comprising:
- an ion modifier including an ionizable terminal group;
- a dye including a compound represented by the following chemical formula:
- A-B;
- wherein A is selected from the group consisting of:
- monoazo dye, polyazo dye, metal complex monoazo dye, metal complex disazo dye, anthraquinone dye, naphthoquinone dye, pyrenequinone dye, triphenylmethane dye, xanthene dye, metal phthalocyanine dye, stilbene dye, nitroso dye, oxazine dye, dioxazine dye, pyrazolone dye and a combination thereof;
- wherein B is selected from the group consisting of:
