Acid dyes definition introduction properties:
Sodium salts of organic acids, especially sodium salts of sulfonic acid and their anion are active color components, are called acid dyes. https://bdfabric.com/silk-and-acrylic-fabric-dyeing-process-by-basic-dye/
Acid dyes Introduction:
Acid dyes are sodium salts of sulfonic acid and, in some cases, sodium salts of carboxylic acids. This dye is applied through Organic or Mineral acid, the active color components of the dye. This dye can also be applied through neutral. These dyes are directly addicted to protein fiber. This dye can be easily applied to wool, silk, and other protein fibers, and polyamide fibers.
Acid dyes definition introduction properties. In 1862, Nicholson discovered the first color of the acid class, alkali blue, by the reaction of suffocation. Many reputable acid dyes are now marketed by reputed companies around the world. This dye is water-soluble and cannot be used directly for cellulose fibers.
Properties of acid dye:
The properties of acid dye are discussed below
1) Acid dye is soluble in water.
2) This dye is always applied with organic and inorganic acids.
3) There is a direct addiction to this dye to protein fiber.
4) Most cellulose fibers cannot absorb acid dyes, but there are some classes of acid dyes that are also addicted to cellulose fibers.
5) Lightfastness and washing fastness of some acid dyes are good.
6) Bright shades of different colors are available by this dye.
6) Sodium salts and ions of most acid dye sulfonic and carboxylic acids are active color components.
6) This dye is addicted to polyamide fiber.
9) Depending on the chemical composition, the fastness of this dye depends on the quality.
10) This dye application method is relatively simple and the price is relatively cheap.
11) This dye is the only dye that is almost exhausted and keeps the dye bath clean after coloring.
