This means that dyes with good light and wash fastness tend to not fade even when they are constantly exposed to light or washed with normal water and soap on a regular basis. These are the kinds of dyes that are used in the textile industries that use dyes in the making of clothes.

Fastness to friction is another property that is commonly demanded from the best manufacturers of dyes and dyestuffs in India. This is a type of fastness that allows the dye to remain in place even after going through wear and tear and friction. The use of such dyes is usually seen in printing and marking of jute bags or packaging bags and boxed made of other materials. These are dyes that need to stand the test of friction and stay strong so that markings made with the dyes remain clear and easy to understand.

Chemical fastness is also an important fastness property that is high in demand among a lot of purchasers of dye products. Chemical fastness is important for dyes that are used on substrates that are chemically treated for any reason. A lot of plastic packing materials and other such marketing materials need to make use of dyes that offer chemical fastness.

It can be concluded by saying that no matter what kind of a dye you need, it is important to make sure that the most viable manufacturer of dyes in India is chosen for the purchase so that you may be able to get the best fastness properties and complete value for your money.

All that You Need to Know About Fast Color Salts

Dyes

fast red B salt

Fast Color Salts or stabilized azoics are used in the combination with Naphthols in the textile industry, for dyeing and printing purpose. These fast color salts are stabilized with metal and are also soluble in water. As a result of this, there is no need to use Hydrochloric acid or Sodium Nitrate. Compared to fast color bases, fast color salts are convenient to use with Naphthols. These salts are safe and eco-friendly and are indispensable when it comes to the dyeing and printing of textiles. Fast Bordeaux GP Salts, Fast Orange GC Salts, Fast Scarlet GG Salt, and Fast Red B Salt, Fast Garnet GBC Salt, Fast Red 3GL Salt, Fast Red TR Salt are the examples of the Fast Color Salts.

Advantages of Using Fast Color Salts

The leading fast salts like fast blue VB salt offers some distinct advantages, some of them are listed here…

  • Wide variety of fast salts readily available of a wide range of products
  • Compatible with a wide array of grounders
  • Available in different shades with different grounders
  • Free-flowing and hence can be customized according to the need and nature of the products
  • Come with high strength and are glossy, thus giving the products an eye-catching, glossy finish

Process of using fast color salts in dyeing

Using fast color salts for printing and dyeing, the process involves several stages.

Salt Development

Dissolve the required quantity of salt in cold water and make sure there is no insoluble part left, for this will give a specky or crystallized dyeing. Add some acetic acid to pH 6.5 to ensure that the shade attains the desired brilliant shade and a proper depth. Then leave the solution like that to give it sufficient time for the full shade to develop so that the maximum color value can be attained.

After Treatment 

Wash the developed goods using sufficient cold water and soap, with the use of 3 GPL soap along with 2 GPL soda ash. Then remove the excess diazodised product, to attain maximum rubbing and washing speed.

Process of using fast color salts in Printing

After Treatment

The printed products are washed with the use of sufficient cold water and soap and boiled using 3 GPL soap along with 2 GPL soda ash. Now remove whatever extra diazotized product is available, for getting the maximum rubbing and washing speed. For the fast red B salt and Blue BB Salt soda, bi-carb is a better option than the acetic acid.

General Mechanism of dissolving fast salt

The dyeing process consists of a couple of stages. In the first step, the material is soaked and saturated with Naphthol solution. The second step involves the development of the material with a diasodised fast salt solution. The fast saltgets chemically combined with Naphthol that is absorbed by the fiber, for lending that insoluble dye on the fiber.

This clears the role of the fast red and blue salts in dyeing products in a safe and eco-hazard-free way.

 

Classification of basic dyes in textiles

Key takeaways of this fundamental post

  1. Importance of basic dyes for textiles
  2. Classification according to processes

Basic dyes

The fashion industry would have been dull if not for the dying of fabrics by the textile industry. The basic dyes involved in coloring of the yarns is one of the key elements that keep several other industries active. As a powerful agent to color and printing, it holds vital importance due to its high tincture values and molecules with a positive charge. The classification shows how it is relevant for acrylic fibers, silk and wool.

Importance of basic dyes for textiles

Polyester is a widely used synesthetic material. It is often augmented with cationic dyes for bright colors. These dyes are salts of organic base. The chromophore in the molecules brings a luster to wool, silk and acrylic textures. They are available as powders, pearls or liquid. The fastness of color is an added advantage for creating beautiful designs and prints. The properties show its solubility in water due to the glacial acetic acid. It dissolves in water easily which is a good factor when a fabric is created.

basic dyeClassification according to processes

The process of dying segregates the basic dyes and their intrinsic values. It is the second last stage after which printing and fabric finishing is done. A good procedure is the key for relevant trade in the textile markets. The right substances and chemicals make all the difference. Usage of certain chemicals ensure the bright color does not fade. Thus it creates a long lasting value fabric for the end consumer. A dye that does not damage the color is important in the process adopted.

The textile industry requires the following processes for their production.

basic dyeSome of the best examples of basic dyes are:

  • Basic red
  • Crystal Violet
  • Methylene blue
  • Basic blue 9

Basic dyes can be modified too.

The chemical composition classifies them by:

  • Diphenylmethane or ketone imine (presence of C=NH group), e.g. C.I. Basic Yellow 1.
  • Triphenylmethane, e.g. C.I. Basic Green 4, C.I. Basic Blue 5 and C.I. Basic Violets 3 and 14.
  • Thiazine (nitrogen and sulphur atoms forming a ring with benzene carbons), e.g. C.I. Basic Blue 9 and C.I. Basic Green 5.
  • Oxazine, similar to thiazine, but nitrogen and oxygen atoms form a ring with benzene carbons, e.g. C.I. Basic Blue 12.
  • Azine, similar to thiazine, but two nitrogen atoms form a ring with benzene carbons, e.g. C.I. Basic Red 5.
  • Xanthene (two benzene rings linked by oxygen atom and methylene bridge) derivatives, e.g. C.I. Basic Violet 10.
  • Acridine (two benzene rings linked by a nitrogen atom and –CH= group) derivatives, e.g. C.I. Basic Orange 14.
  • Azo groups, e.g. C.I. Basic Brown 1.

Other applications of importance

They can be used also for dried flowers, coir, jute coloring cut flowers. But the major use is for dying acrylic fibers due to the anionic groups attached to them. The cation and anion create the salt linkage. In the case of leather, the dying procedure is blended with vegetable-tanned leather. It does away with the mordant. In the paper industry too the coloring process holds advantage for printing.

Benefits of 3 types of acid dyes

Dyes,

 Acid dyes

Acid dyes are safe to use in the textile and food industries as long as they are handled with care. Just as a dyer works with other concentrated powdered dye or chemical it cannot be done without the dust mask and gloves. The benefits of acid dyes are mainly to bond the protein fibers. Its affinity for staying softer and silkier adds weight to its wide applications due to its solubility and light fastness of color.

Vipul Organics, has been in the business of pigments and dyes long enough to provide insight

about various dyes and how they impact various industries.

Key takeaways:

  • Understanding the chemical dye chemistry
  • Why acid dyes are valued for fastness
  • Industrial applications other than textiles
  • Advantage of dealing with Vipul Organics

Structural part

  • It consists of molecular group –S03H
  • The pH is mild like white vinegar/critic acid
  • Ideal for silk rinses as it tends to restore the softness quotient
  • The dye is non-toxic
  • Ideal for applications in the textile industry for dying cotton, silk, nylon and wool.

The actual structure falls in 4 categories depending on the molecular group.

  1. Azo
  2. Anthraquinone
  3. Premetalized
  4. Triphenylmethane

Sometimes the same dyes may fall in one or more categories. But they all have –S03H which get attached to the amino groups of the fiber. The Azo dyes are considered acid red. The structure is Ph-N=n-Ph. They are primarily used on cellulose fabrics i.e. cotton or rayon.

Why acid dyes are valued for fastness qualities?

The dyes are mainly used under acidic conditions and they are characterized by two factors:

  1. How they dissolve in water
  2. Amphoteric affinity for the fiber

Good customer ratings of fastness are critical for their significance. Good quality processes ensure there is no fading (of fabric) even after repeated washes. Hence, it is also successfully used for art and art printing. It offers a premium finish to the final fabric.

Industrial applications

It is well known fact the entire textile sector uses a variety of acid dyes for fabric enhancements and coloring. In the textile industry it is used to treat silk in several color tones. In low temperatures the dyes are treated. When it is used on wool there is a salt link between the dye molecule and fiber polymer.

But there are other sectors also where they are applicable successfully like:

  • Fertilizers
  • Leather
  • Detergents & metal nodization
  • Coolants for engines
