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. We are foremost organization engaged in manufacturing and supplying Acid Dyes. 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
Acid dyes can be grouped into three classes relying upon the leveling properties, economy of the dyeing and fastness properties
| 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 |
| 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 |
