Reactive dyes are cationic dyes, widely used for dyeing cellulose, protein and polyamide fibres. In past days, cellulose fibres were dyed with Direct or Vat dyes. However, later with the introduction of reactive dyes Direct and Vat dyes were substituted with Reactive dyes.
The advantages of Reactive dyes over Direct Dyes are as follows:
- Ability to procedure bright shades of wide range
- High levelling quality
- Good washing fastness
- Good light fastness
The advantages of Reactive dyes over Vat Dyes are as follows:
- One stage simple dyeing method
- Low temperature dyeing at less than 1000C
- Less expensive
Reactive dyes even substituted Metalized Azo dyes with more fastness and bright shade dyeing capacity.
Besides, clothes, reactive dyes are also used in paints, plastics, food, etc.
Direct Dyes are widely used in both textile and non-textile application.Common application of Direct Dyes are made on cellulose, polyimide, silk, leather, paper, PC blends. Direct Dyes are most commonly used on cotton fibres. Anionic Direct Dyes are used for coloring papers, controlling tint, shade and corrections of two sided paper color. Direct Dyes can be used in same dye bath with Acid Dyes which is considered to be major benefit.
Acid dyes are mainly used in fibres and medical purposes. Acid dyes used for textile proves effective on protein fibres viz. animal hair fibres like mohair, alpaca and wool. They give good results when applied on fibres like silk, synthetic fibre nylon, modified acrylic fibres using neutral to acid dye baths. Acid dyes for medical purposes are used to stain basic tissue proteins while microscopic examination for research and diagnosis. Some acid dyes are also used as food
Primarily, basic dyes are prominently used for jute dyeing and jute printing but also used on silk, wool, acrylic and modified acrylic fibres. Our dyes of ink and paper are widely accepted for its high quality results. They are also used to color dried flowers, cut flowers and coir. Once, basic colorant was used extensively to dye leather due to its capability to combining directly with vegetable tanned leather without the use of any mordant. The application of these dyes is very similar to direct dyes with caution that it requires precise controls over temperature and auxiliary.
We are food dyes supplier which are used both in domestic cooking as well as commercial food production. Considering safety parameters, they are also used in several non-food products like cosmetics, home craft projects, pharmaceuticals and medical devices.
Our color additive are used to give color to alcoholic and non-alcoholic drinks and beverages, dairy products, pickles, sauces and seasonings, baked food, jam and jellies, chewing gums, chocolates, dessert edible ices and confectionery, canned products, food decoration and coating items.

Apart from eatables, food coloring substance are also used in pesticides, animal feeds, washing powder, pharma tablets and capsules, wax colors, writing inks, toothpaste, and toiletry products like bath soaps, shampoo, cold crème.
Solvent dyes are used to color organic solvents, hydrocarbon fuels, lubricants, wax, plastics and other hydrocarbon-based non-polar materials. Our dyes for ink are used ball point pens, marking pens, printing inks, foil printing, polishes, leathers, wood stain, acrylic resin, varnishes and shellacs. They are also used in automotive lubricants, cutting industry, signalling smoke and pyrotechnics industry. In plastic community, solvent dyes are used to color variety of solid materials like nylon, polyester, acetates, acrylics, PVC, PMMA, PETP, polystyrene and styrene monomers. Many solvent dyes are used to produce stains to identify various cell structure components in scientific research and medical diagnostics.
We are dyes manufacturer India offering pure and low impurity solvent dyes. We fulfil special needs of plastic coloration. Our solvent dyes withstand over 350 degrees C of temperature during extrusion and injection during plastic moulding process.
