[Production usage ]
This product is mainly used for dyeing nylon/spandex blended fabric with acid dye to improve the coloring rate of spandex without affecting the wet fastness of soaping, sweat stains, water stains, blisters, etc.
[Mechanism of action ]
Under acidic conditions, the spandex coloring agent reacts with the ionized amide bond and other groups in the spandex to modify the spandex fiber so that the spandex fiber has amino groups, which can be ionically bonded with anionic acid dyes to achieve spandex. The purpose of dyeing.
