RED SUN DYE CHEM was incorporated 15 years ago as a small scale dyestuff manufacturing unit, today RED SUN DYE CHEM has emerged as a leading business conglomerate in dyestuff industry. We are Acid Dyes Manufacturer, Supplier and Exporter from India. 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. We are also considered to the best manufacturer and exporter of reactive dyes, basic dyes, acid dyes, solvent dyes globally in countries like Algeria, Brazil, China, Egypt, Itlay, South Africa, Turkey, Spain, Vietnam.
ACID dyes are water-soluble dyes that are commonly used to dye natural fibers such as wool, silk, and nylon. The name "ACID" refers to the fact that these dyes are typically applied in an acidic environment, which helps to increase their solubility and ensure that they bond effectively with the fibers.ACID dyes are typically composed of a complex organic molecule that includes both acidic and basic groups. These groups help the dye to bond with the fiber in a process known as "ionic bonding." The acidic groups on the dye molecule bond with the positively charged amino groups on the fiber, while the basic groups on the dye molecule bond with the negatively charged carboxylic groups on the fiber.
ACID dyes are known for their bright and vibrant colors, and they are often used in the textile industry to create colorful fabrics and garments. However, they can be difficult to work with, as they require careful control of the pH and temperature of the dye bath in order to achieve optimal results.We are manufacturer and supplier of acid Dyes. Additionally, ACID dyes are not very lightfast, which means that they can fade over time when exposed to sunlight or other sources of UV radiation.
Acid dyes offer a wide range of bright and vibrant colors that are ideal for dyeing protein fibers. They are also highly concentrated, so a small amount of dye can produce a strong color. Acid dyes are commonly used in the textile industry to dye wool and silk fabrics for clothing and home decor. Our company's prepared Acid Violet Dyes, Acid Black Dyes, Acid Orange Dyes are also much supplied and exported acid dyes to the lots of consumers of food processing, textile, paint and more types of industries in a large quantity order basis.They are also used in the production of nylon stockings and other synthetic fibers.
In the paper industry, acid dyes are used to color paper, particularly for artistic and decorative purposes. Acid dyes can produce a range of colors and shades, from bright and vivid to muted and subtle. we are still the leading Acid Dyes Exporter in India because our trade reaches to the major number of regular clients from the many African, Asian, European countries like Canada, Argentina, Peru, USA, Mexico, and Brazil.The dye can be applied to the paper in various ways, such as by immersion, spraying, or painting. The resulting color is typically more washfast and lightfast than that produced by direct dyes.
Acid dyes are a class of synthetic, water-soluble dyes that are primarily used to color protein fibers such as wool, silk, and nylon. They are called "acid" dyes because they are typically applied to the fiber in an acidic solution. we "Red Sun Dye Chem" are the Acid Dyes Supplier in Gujarat and as well the greatly familiar Manufacturer and Exporter of very pure quality of acid dyes in Ahmedabad, India. The acidic environment helps to protonate the dye molecules, allowing them to bind more strongly to the fiber.
direct dyes, acid dyes require a mordant or fixing agent to help the dye molecules attach to the fiber. The mordant can be an acidic substance such as vinegar or a metallic salt such as aluminum sulfate. The mordant helps to create a stronger bond between the dye molecules and the fiber, resulting in a more washfast and lightfast color. Our company's prepared Acid Violet Dyes, Acid Black Dyes, Acid Orange Dyes are also much supplied and exported acid dyes
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 |
