What is Acid Dyes?

Acid Dyes name derived from the use of an acidic dye bath. Any type of a dyes class containing one or more acidic groups, which is used in acid solution for dyeing wool and silk.

Our offered Acid Dyes are utilized to dye protein fibers such as wool, angora, cashmere, and silk, as well the milk protein fiber called as Silk Latte, the soy protein fiber called Soy Silk and the Synthetic Polyamide Fiber for nylon. Acid Dyes are so called since they hold acidic molecular groups such as S03H and work in a low pH environment with a mildly acidic & fixative & like white vinegar or citric acid as mentioned above.

Our offered Acid Dyes are highly water soluble, as they hold good light fastness. The strength (fastness) of this bond is related to the desire/ chemistry of the dye to remain dissolved in water over fixation to the fiber. Acid dyes generally contain sodium salts of sulphonic acids, or less frequently of carboxylic acids, and therefore they are anionic in aqueous solutions. Our products are used in industries like Acid Dyes for Leather, Acid Dyes for Dyeing, Acid Dyes for Paper, Acid Dyes for Nylon, Acid Dyes for Acrylic Fibers, Acid Dyes for Wood Coatings.

The chemistry and chemical structure of acid dyes is complex in structure and diverse having a sulphonyl or amino group which makes them soluble in water. Our Acid dyes are associated in basic three structure molecules to the following

  • Anthraquinon type
  • Azo dye type
  • Triphenylmethane type
Chemical Structure of Acid Dyes

Different Types of Acid Dyes

Acid dyes can be grouped into three classes relying upon the leveling properties, economy of the dyeing and fastness properties

  • Neutral acid dyes : Supra milling or fast acid dyes they have medium to good wet fastness properties, some of them have low light fastness in pale shades . Usually, these acid dyes are used as self shades only. These are applied to the fiber in a weakly acid pH.
  • Weak acid dyes : These dyes belong to the milling class of dyes. These acid dyes have good fastness properties; light fastness is moderate.
  • Strong acid dyes : Acid dyes applied in a strongly acidic medium and called also leveling dyes, wet fastness properties limited. These acid dyes are suitable to produce the combination shades. (E.g. yellow, red, blue).

Classifications and Characteristics of Acid Dyes

Properties Leveling acid dyes Milling acid dyes Super milling acid dyes
Introduction Corresponds to molecularly split acid dyes,light fastness is generally good, exhaustion is satisfactory also referred to as "strong acid dyes". Correspond to partially aggregate used where good washing fastness is the main consideration, also referred to as "week acid dyes". Applied from neutral solutions, don't form true solution in water but form colloidal dispersed solution, on boiling they split, also referred to as "neutral acid dyes".
Additive to bath Sulphuric acid Acetic acid Ammonium acetate
pH 2-4 4-6 6-7
Leveling property Good Moderate Very poor
Wet fastness Poor Good Very good
Molecular weight Low High High
Solubility in water High Low Low
State of division in water Molecularly split Colloidal Colloidal
Affinity to protein Low High Very high
Action on cellulosic fiber No staining Staining Staining

Properties of Acid Dyes

Strong Acid Dye Weak Acid Dye Neutral Acid Dye
Dye leveling property is very good Dye leveling property is moderate. Dye leveling power is very poor. So, its usage is very rare.
Strong acids are generally used in this bath Weak acid is used in the dyeing bath Neutral medium is used for dyeing
Its light fastness property is excellent but wet fastness property is not so good PH value is maintained 5.2 - 6.2 PH value around 7
Here we always have to maintain the PH value 2-3 Washing fastness property is good Light fastness property is good
It can be used for cellulosic fibre dyeing Washing fastness property is also good
