All That Happens When Fabrics are Dyed with Vat Dyes

Dyes

Vat dye is a name that the kind of dye is given owing to the way in which it is used. The dye is used by diluting into liquid form and applying on to a fabric by using a vat or a bucket like vessel. Since a bucket or a vat is used in the application of the dye, it gets the name Vat dye. The dye is very commonly used in the coloring of fabrics like cotton and other similar fabrics that are mainly cellulosic in nature. The dye is extremely popular and put to use in India by major fabric manufacturers along with manufacturers of fabrics outside the country.

When you choose to get your vat dyes from the most trusted vat dye manufacturers in India, you can be sure about getting it in bespoke forms and quantities. The best manufacturers offer the dyes in powdered as well as paste forms, which can both be used equally comfortably in the dying of fabrics. This is one of the most important reasons why the dye is high in demand among manufacturers of fabrics across the globe. Originally, the vat dyes were found majorly in indigo color since it was naturally produced with by the fermentation of the indigo plants. However, in the modern times, the right manufacturer of vat dyes can help you get your hands on a wide range of shades apart from indigo, as they are created synthetically.

There are lots of reasons why vat dyes are demanded and in general used by fabric manufacturers. One extremely important reason for the demand and the popularity of the dyes is the convenience in use that it offers. With the help of a mix of hot liquid and the vat dye of your choice in a bucket, you get a concoction that can ensure the coloration of a large amount of cloth. This means that an industrial unit, irrespective of whether it is large or small, would have to put in limited amount of resources, time and effort in the dying of large amounts of fabrics.

Another reason why vat dyes are a go-to material in the dying of fabrics is because of the fact that it offer excellent fastness. You name it and the dye is fast to it, which implies that you get all-round fastness. Right from light fastness to water and chemical fastness and even heat fastness, you get it all when you choose to opt for vat dying with the use of vat dyes from the best manufacturers in the country. This is a win-win for the users of the vat dyes and their set of clients because fabrics dyed using vat dyes remain looking like new for a much longer time, offering complete value for money for the end users of the fabrics as well.

While there are numerous benefits and plus points of making use of vat dyes in the dying of cotton and other cellulosic fibers, it is also important to make sure that you have the right manufacturer at your service!

Why low dispersion is critical?

Manufacturers try to address the challenges by keeping a strict eye on the client requirement. Take for example, in coatings the properties are strong only when the dispersion is optimal. If it does not contain the desired strength for tinting the efficiency of the product is reduced. It also results in a very high formulation cost which is not feasible to any involved party. The pigment needs to be balanced with color development and processing expenditures by grinding pigments. The dispersion is required either for a single production system or complex nature of a product. If the pigment dispersion is easy it adds to the stability, consistency and eventually the profitability of the product. Constantly new developments in this area are used to improve performance and reduce energy consumption.

Improved dispersion quality with pigment 112

There are many ways in which the dispersible pigments are processed. In the case of pigment 112 the focus is on surface modification, its treatment and coverage. There is a possible use of reagents to displace water with alkyds resins or cellulose. Pigment 112 I commonly used in industrial applications due to versatile coloring properties. It is referred as a naphthol AS pigment which can be dispersed finely with the binder. Its improved dispersibility provides a longer shelf life to the product and reduced storage loss. Several water borne coatings are enhanced by this process and usage of this pigment. Seed coating in the agricultural sector is used for crop protection from diseases and pests. The coloring properties of this pigment ensure that the seeds are not affected by environmental changes and provide vigor for nutritional value.

Choice of pigment paste in aqueous system

A client is always looking for cost effective solutions and creating a technical differentiation is important. The development of Suncoat pigment dispersion for paint & coats are very distinctive in their properties. The stability is mainly because of the testing done in labs to create high quality formulation. With the right shade card each client is offered a customized solution. The challenge to create a good appearance is done with latest technology and efficient processes in the manufacturing unit. There is a control over the cost of production for a wide variety of industrial applications. The less dispersant provides the paint coating to be least corrosive.

Critical Properties of Pthalocyanine Pigment Dispersion Needed for Coatings & Paints

Uncategorized

pthalocyanine pigments

Color coatings with higherbrightness and color strength are results of flawless dispersion of pigments. It is because of the optimal size of the pigment particle, and the long-term stabilization of the particles dispersed in the formulation. It shows how important dispersion of pigments is and the role it plays in the visual outcome of a coat of paint on a surface.

Let us discuss a brief account of pigment dispersion. Technically speaking, pigment dispersion in inks, paints, and liquid coating that produce stable suspension come up with three distinct essential properties.

Stability

When it comes to pigment dispersions for printing on textiles, then pthalocyanine pigments will be the best option because of their stability. These pigments come with the highest degree of stability and are the finest in terms of dimension, and these two properties help these pigments to provide a spectacular color and visual appeal to the apparel. Pigment dispersion is taking the center stage, as they are gradually replacing dyes of late, thus providing more thermal and light stability to the apparel. These pigments come up with a great extent of opacity and they are water-based. This is the reason, leading manufacturers of Phthalocyanine pigments enjoy such a special status in the industry today.

Automatic Dispersion Property

These high-quality pigments are also auto soluble and are multi-compatible solvent dyes, with the capacity of easily dissolving in any solution. Using, for instance, Pigment Red 53.1 or any other kind of similar pigment means, the production speed will be faster with the drastic reduction of the overall turnaround time of producing the finished product, as these pigments dry out faster. This means increased production at the end of the day.

Lower Level of Viscosity

Another advantage of using their pigments is that they ensure the production of better quality paints and coating thereof, due to uniform dispersion of pigments because of a lower level of viscosity. This ensures better distribution of pigment dispersions. Thus, if you opt for, say, Phthalocyanine Blue 15.0 it will surely give you better effect than any inferior quality of paint.

Eco-friendly

Pigment dispersions do not generate any toxins and are hence never a threat to the health and environment. With the environmental laws becoming stricter, more are more manufacturers are opting for paints with these pigments, which are free of formaldehyde, AZO pigments, and APEO, all of which are infamous for causing health and eco hazards.

Customizable

Pigment dispersions are customizable to make them compatible with the product in question. For instance, though pigments are opaque, they can be turned into transparent so that they meet the needs of the manufactured products. The strength, as well as the shade of dispersion, can also be specified and delivered.

Optimal Size of the Pigment

Pigment size is another critical property that needs to be taken into account while choosing pigment dispersion. The larger is the particle size, get better the opacity. However, pigment dispersion for the smaller particles shows off better transparency like this, which in turn paves the way for improved dispersion.

So these are the critical properties of pigment dispersion that you need to keep in mind. 

 

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.

Vipul Organics understands the need for basic dyes in today’s competitive world. With a well equipped facility, it is the primary source and partner for several customers who need dyes and pigments to augment their textile product lines.

 

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
