Acidic Mordant Dyes

Metal mordant dyeing is a traditional dyeing technique that has been used for plant dyeing since ancient times, but it is inherited as a metal mordant of acid mordant dyes (chromium, cobalt, iron, aluminum, copper, etc.) in modern times, and is the mainstream in wool dyeing.
Yamada Chemical's acid mordant dyes are used to dye wool, animal hair such as cashmere and angora, and silk and nylon.
Metal mordanting is used to develop a deep hue and excellent sturdiness (light resistance, washing, rubbing, etc.) by forming a metal complex by binding an acid mordant dye and metal in the fiber in the dyeing process.
Taking advantage of this feature, Yamada Chemical's acidic mordant dyes achieve high washing fastness (no need for fixing) for deep dyeing of wool suits and black dyeing of nylon innerwear (tights, stockings, socks, etc.). I am.
Cobalt mordant dyes for wool have excellent light durability and are used in uniforms. Even in the black dyeing of silk, it is highly praised for its superior texture to other types of dyes such as reactive dyes. 
In rare cases, Yamada Chemical's acid mordant dyes are also used in the field of wood dyeing. We are contributing to the production of beautiful colored wood made from dyed plantation wood, which is an alternative to natural precious wood, which is facing global depletion.
As a domestic manufacturer of these acid mordant dyes, Yamada Chemical has achieved the industry's top performance and specifications, and has earned the high reputation and trust that only domestically produced products can receive from the dyeing industry.
