What are Dyes and Pigments? What is the Difference between dyes and pigments?

Dyes and pigments are the elements that give a material colour. Both dyes and pigments, commonly known as dyestuffs, are frequently referred to as colourants. The size of the particle is the main distinction between colours and pigments. Compared to pigments, dyes are significantly finer. In contrast to pigments, which are typically UV stable, dyes are not. Users of dyes typically purchase their goods from dealers of the items or dyes and pigments companies in India. 

Dyes, also referred to as colourants because the colouring substance is dissolved in a liquid, penetrate the substance to which they are administered. The quality of the goods you receive from the basic dye manufacturers in India is one thing they won't skimp on.

Contrarily, pigments are made up of incredibly small pieces of crushed colouring material contained in a liquid to create a paint coating that adheres to the substrate it is administered to. Since they easily penetrate the solid slab and do not fade out during the polishing stage, dyes are employed in the polished concrete process.

		Dyes	Pigments
1.	Solubility	Highly soluble in liquids	Water and the majority of solvents cannot dissolve it
2.	Number	Readily available in a large number	Significantly fewer in number
3.	Lightfastness	Lower dyes are extremely susceptible. Lights disintegrate coloured materials by rupturing molecular electrical bonds.	Historically, it has been discovered that pigments are lightfast than dyes.
4.	Product resistance	Low in comparison to pigments	High
5.	Size	Comparing dye molecules, for instance, a head of a pin would be like connecting a football (pigment) to a dye molecule (dye)	The size of pigment particles ranges from 1-2 microns. It implies that a magnifying lens can be used to observe the particles.
6	Bonding	Electrostatic charges on dye molecules act as a means of adhering the dye to the concrete.	A binder is needed to help glue pigment together. Due to the fact that it is an inactive chemical that is only maintained in a carrier or binder
7.	Imparting colours	With the selective absorption of the dyes, dyes can add colour	Pigments either scatter light or selectively absorb it to produce colour
8.	Combustible Properties	Combustible	Non-combustible
9.	Chemical Composition	Organic compounds	Mostly inorganic substances, frequently including highly hazardous metals
10.	Longevity	Not as durable as pigments	Long-lasting compared to dyes

Acrylic Fabric: Characteristics, Production, & Process

 

Fabric made by acrylic dyes manufacturers in India is often referred to as polyacrylonitrile, acrylic, or acrylonitrile. Synthetic polyacrylonitrile polymer is the fabric's main component. Variations in the fabrics thread count range from 18 to 100. Despite having a low fabric breathability, it is very moisture-wicking. It is quite good at retaining heat. 

Acrylic fabrics have a very high stretch ability. The likelihood of piling or bubbling is very high. The USA is the nation where the fabric was first made. Presently, China is the largest exporting and producing nation. Warm washing temperatures are advised. They are frequently used in garments including sweaters, hoodies, boots, boot linings, hats, gloves, sporting gear, carpeting, blankets, roller brushes, upholstery, area rugs, protective gear, wigs, and hair extensions.

 

What Is Acrylic Fabric Made of?

Fabrics with acrylic fibres are created using the synthetic material acrylonitrile. Acrylic fabric is made from a form of fibre that is derived from fossil fuels since it is created by reacting specific chemicals with a variety of monomers that have a petroleum or coal base.

Since the acrylic fabric is one of the least breathable textile types available, it is preferred for applications requiring heat retention. Acrylic Dyes Manufacturers, For instance, tracksuits, hoodies, and athletic pants are frequently constructed of acrylic fabric, which is frequently used in athletic equipment. However, there are worries that acrylic could be cancer-causing, so it might be best to avoid coming into touch with this fibre.

Authentic acrylic fibre must contain at least 85% acrylonitrile; it may also contain minor percentages of other synthetic substances. The properties of the finished cloth will differ depending on the substances that are combined with acrylonitrile.

The Evolution of Acrylic Fabrics

The American DuPont Corporation invented acrylic fibre first, as it did with many other synthetic textile fibres. When acrylic fibre was created in the 1940s, the world saw this innovation as simply the next step in DuPont's quick rise to a dominant position in the global textile markets. This company had already gained notoriety throughout the world for the development of nylon and the mainstreaming of polyester production.

The advantages of acrylic became increasingly clear over around ten years, and this fabric steadily increased its market share. Consumers and business leaders at the time believed that synthetic fibres will soon completely replace natural fabrics. Consumers started to worry about acrylic's flammability over time, though, especially since wool, which acrylic was meant to replace, has one of the best flammability profiles of any fabric. However, DuPont is no longer the main supplier of acrylic fibre. The market for acrylic fibre is now led by businesses in China, India, Indonesia, and other ASEAN nations rather than this American firm. Similar to how emerging markets in developing countries want considerably less acrylic fabric, so does the American consumer market.

 Washing 

Remember that clothing made of acrylic fabric can be damaged by both hot and cold water. As a result, you should always use warm water to wash acrylic apparel. When washed in water that is too hot, acrylic can melt and harm your washing machine or other items in the load. When washed in the cold, acrylic can start to become stiff and rigid.

Additionally, more than any other fabric, the acrylic fabric is more likely to pill. A piece of clothing covered in pills the same colour as the clothes you cleaned it with will result from washing an acrylic item with clothes that don't nearly match its hue.

Customers who purchase dyes can purchase them from retailers who sell them or from renowned top dye manufacturers in India. 

How Is Acrylic Fabric Made?

There are seven phases involved in the creation of acrylic fabrics.

Step 1:

Polymerization 

The chemical process known as free radical polymerization uses a water-based solution to produce the acrylonitrile polymer polyacrylonitrile.

Step 2:

Dissolving 

Using a powerful chemical solvent, this polymer is broken down.

Step3:

Extruding

After that, the substance, which resembles gel, is prepared to be spun into acrylic fabric by an extruder. 

Step 4:

Wet or dry spinning 

Wet spinning or dry spinning, which includes evaporating the solvent with a stream of hot gas, is the common method for coagulating these fibres in a solution of the same solvent. 

Step 5:

Washing and stretching 

In order to create long, thin filaments that may be spun into yarn, the resulting fibres are then cleaned, stretched, and crimped.

Step 6:

Leading 

After being spun into yarn, acrylic fibres are put onto bobbins and delivered to companies that make textile products.

Step 7:

Weaving

These producers then use this acrylic yarn for clothing, carpeting, or a variety of other uses.

In order to create long, thin filaments that can be spun into yarn, the resulting fibres are next cleaned, stretched, and crimped. Stretching acrylic fibres, like other synthetic textile fibres, results in them being multiplied by many times their original length, which lowers costs and boosts production efficiency. Stretching is necessary to produce a usable end textile. Workers may also expose acrylic fibre to different colours and treatments at the manufacturing plant or the facility that produces textile products. For example, flame retardants are a definite requirement for acrylic fabrics; without these harsh treatments, the acrylic fabric would be extremely risky.

How is a fabric made of acrylic used?

●   Used for clothes, including gloves, hoodies, slacks, and many other sorts of cold-weather attire. 

●        Utilised in rugs, upholstery, and carpets for home ware products

●        For costumes and props

●        Regarding knitting supplies.

 

Top Acrylic Dyes Manufacturers in India is utilised in many of the same applications as this extremely well-liked natural fibre since it is made to resemble wool. For instance, clothing companies use acrylic fibre to create a variety of cold-weather clothing items, including hoodies, slacks, gloves, mittens, and sweaters. Additionally, carpeting, upholstery, rugs, and other historically dominated by wool home ware product categories are all commonly made from acrylic.

Although acrylic naturally resembles wool quite closely, depending on the spinning technique employed, it can also be made to resemble other fabrics, such as cotton. Manufacturers may create acrylic materials that resemble fur, which might be helpful for costumes or props.

One of the components of carbon fibre, which is highly sought-after in industrial applications, is acrylic fibre. Despite being extremely durable, acrylic fibre doesn't have many industrial uses due to its flammability, which prevents it from being used in a variety of industrial settings.

Knitting is one of the most popular uses for acrylic fibre. Despite several drawbacks, acrylic knitting has a vital role in the market for hobbyist knitters due to its inexpensive cost and inability to lose colour. 

Customers of dyes get their goods from Dyes and Pigments Manufacturers in India or from retailers who sell those products.

 

Types Of Dyes And Their Properties

 What are dyes?

A dye is used to add colour to different materials. Dye Manufacturers in India, For humans, colour has always held great fascination and appeal. Both natural and synthetic dyes are common types. They give kitchenware, textiles, leather goods, and even food products colour. For colouring various items, several dyes are available. The finely crushed substances found in paint, ink, and other goods that are called pigments are not dyes. In contrast to pigments, which are inorganic substances, dyes are organic substances. Everything these days comes in a variety of hues and textures. And the enormous array of colours makes this possible.

Various Types Of Dyes:

Basic Dyes

These colours are generated synthetically and cannot dissolve in water. They also go by the name of cationic dyes. Basic Dyes Manufacturers in India. These dyes have a good retention period and all of their shades are very brilliant. Acrylic fibres are coloured using basic dyes, which are reasonably priced. They react well with synthetic materials.

Vat Dyes

Vat dyes, commonly referred to as indigo dyes, are produced utilising a variety of plants. Vat dyes are applied by a method known as vatting rather than directly colouring the substrate. These dyes are insoluble in water and must be vetted to become soluble. The particles in vat dyes are quite tiny compared to other dyes. These come in fewer tints and colours. Experts typically utilise vat dyes because of the lengthy dyeing procedure.

Direct dyes

They are used to colour cellulose textiles like cotton since they are soluble in water. When utilising these kinds of dyes, dyeing is often carried out in an alkaline environment. But all the materials dyes using this type of dye require after-treatment and care to improve the shade of the dye. Direct Dyes have excellent fastness characteristics. The textile industry makes substantial use of these colours.

Acid Dyes

They are frequently used to colour protein fabrics including nylon, silk, and wool. These colours are very water-soluble. They are inappropriate for use with cellulosic material. Acid dyes work well to colour leather and other medicinal items since they have good dye fastness properties. They're excellent for the food business as well. They are also used to produce ink such as ink for printers, ballpoint pens, marker ink, ink pads, etc.

Synthetic Dyes

These artificial dyes are created chemically. They come in a wide variety of hues and tones. Because of their relatively low cost and simplicity of usage, they are used in many different sectors. Both the ecosystem and the human body are harmed by it. Yet, the use of these colours continues to grow. Some chemical substances are water-soluble.

Reactive Dyes

For cellulose, protein, and polyamide fibres reactive dyes work well. These dyes are simple to use because they come in a variety of formats. They have good light-fastness qualities and are soluble in water. Since all reactive dyes come in vibrant hues, they are ideal for the textile sector. These reactive dyes are affordable and suitable for use in large quantities. They block UV radiation and have an excellent electron arrangement.

Solvent Dyes

The emerging textile mills employ these contemporary colours extensively. Solvent dyes are non-corrosive, non-toxic, and non-flammable dyes. The fibres and polymers can be coloured more quickly and easily with these dyes. They are also quite wettable. These dyes have a significant downside in that bulk application is challenging due to the solvent’s frequently high cost. Solvent dyes come in a wide variety and make excellent alternatives to traditional, hazardous dyes.

Food Dyes

These are the synthetic colours that have been added to the meal to make it more appealing. These days, food colours are frequently utilised. The several forms they come in include pastes, liquid colours, gels, and coloured powders. These food colouring agents are used to restore the edible's colour after it has been exposed to light, heat, and storage. Food dyes must be used with caution because using them excessively might lead to several health issues. There are two types of food dyes: natural and artificial. Natural food colours can make meals more appealing and nutrient-dense. Before choosing the best food dye, exercise caution and undertake a thorough study.

Seed Colouring dyes

To help farmers to distinguish and identify different types of seeds, seed colouring dye is used to give colour to the seeds. Many kinds of seeds have various colours. The traditional method of protecting seeds and promoting plant growth is seed colouration. This strategy has also been used by major seed companies to brand their seeds. Seed colouring is a fantastic technique to distinguish the seeds and stop them from being harmed. These days, a variety of seed dyes are offered; try to select a safe dye as this can affect the growth of the plants and crops.

Conclusion 

The dyes mentioned above are just a few of the many different kinds of dyes available. Each of them has advantages and disadvantages. Depending on the product’s kind and intended usage, one must select the dye that is best for them. Veeraco Colourants Pvt Ltd is one of the best dye manufacturers of India with generations engaged in the business, they are one of the Top Dyes Manufacturers in India and have been fulfilling the colouring needs of the world for ages.

What is Dyes and Pigments? Advantages and Disadvantages

 

Dyes and pigments are both types of colorants used to add color to various materials. However, there are some key differences between the dyes and pigments.

Dyes are colorants that are soluble in a liquid solvent. When a dye is added to a material, it dissolves into the material, creating a uniform and transparent color. Dye Manufacturers in India, Dyes are commonly used to color fabrics, paper, textile, leather and other materials.

Pigments, on the other hand, are insoluble particles that are mixed with a binding agent to create a paste or powder. When applied to a material, the pigment particles are dispersed but not dissolved, creating an opaque and non-uniform color. Pigments are commonly used in paints, inks, plastics, fabrics, cosmetics and food.

Another key difference between dyes and pigments is their durability. Dyes tend to be less durable than pigments, as they can fade or bleed over time, especially if exposed to sunlight or washing. Pigments, on the other hand, are more resistant to fading and are often used in applications that require long-lasting color, such as outdoor paints.

Dyes:

1.     Dyes can be derived from natural sources, such as plants and animals, or they can be synthetic, produced through chemical processes.
2.      Dyes are typically used on materials that have a high affinity for the dye molecule, such as cotton, silk, and wool.
3.     Dyes can be categorized into different types based on their chemistry, such as acid dyes, basic dyes, and direct dyes.
4.      Dyes can also be classified based on their application method, such as immersion dyeing, printing, and spray dyeing.

Pigments:

1.     Pigments can be organic (carbon-based) or inorganic (metal-based) compounds, and they can be derived from natural sources or synthesized in a laboratory.
2.       Pigments are typically used on materials that have a low affinity for the pigment particles, such as plastics and metals.
3.     Pigments can be categorized into different types based on their chemical composition, such as titanium dioxide, iron oxide, and phthalocyanine blue.
4.    Pigments can also be classified based on their particle size, such as Nano-pigments, micro-pigments, and macro-pigments.

Top Dyes Manufacturers in India, describes both dyes and pigments have advantages and disadvantages, and the choice between the two depends on the specific application and desired outcome. For example, dyes are often preferred for coloring fabrics, as they provide a more even and vibrant color, while pigments are often preferred for painting and printing, as they offer a wider range of colors and greater durability.

What is the difference between Basic Dyes and Sulphur dyes?

Basic dyes and Sulphur dyes are two types of colorants used in textile dyeing. The main differences between them are:

Chemical Structure: Basic dyes are water-soluble cationic dyes that are derived from bases such as Triphenylmethane, xanthene, or methylene blue. On the other hand, sulphur dyes are water-insoluble anionic dyes that contain sulphur -containing groups, such as thio groups.

Dyeing Mechanism: Basic dyes manufacturers in India, are primarily used for dyeing acrylic and cationic dye able polyester fibers by forming an electrostatic attraction between the positively charged dye molecule and the negatively charged fiber surface. On the other hand, sulphur dyes are used for dyeing natural fibers, such as cotton, wool, and silk, by forming a covalent bond with the fiber surface.

Color Fastness: Basic dyes have poor color fastness properties and tend to fade easily when exposed to light, water, or chemicals. On the other hand, sulphur dyes have excellent color fastness properties, particularly to light and washing, and are widely used for dyeing dark shades of cotton.

Environmental Impact: Basic dyes are considered to be more environmentally hazardous than sulphur dyes because of their toxicity and potential to contaminate water resources. sulphur dyes, on the other hand, are considered to be relatively safe and eco-friendly due to their low toxicity and biodegradability.

Application: Basic dyes are commonly used for bright, vibrant colors such as red, pink, and blue, while sulphur dyes are often used for darker shades such as black, brown, and navy.

pH Sensitivity: Basic dyes require an alkaline pH for effective dyeing, while sulphur dyes manufacturers in India, sulphur dyes require an acidic pH. This difference in pH sensitivity affects the dyeing conditions and may require different chemicals to adjust the pH levels.

Fiber Compatibility: Basic dyes are typically used on synthetic fibers such as nylon, acrylic, and polyester, while sulphur dyes are commonly used on natural fibers such as cotton, wool, and silk. However, some blends of synthetic and natural fibers can be dyed with either type of dye.

Dyeing Process: Basic dyes are typically applied in a one-bath process, where the dye is added to a bath of hot water and the fabric is immersed and agitated. sulphur dyes, on the other hand, require a two-bath process, where the fabric is first treated with a reducing agent to open up the fiber structure and create reactive sites, and then immersed in a bath of the  sulphur dye.

Cost: Basic dyes are generally less expensive than sulphur dyes, but this can vary depending on the specific dye and the quantity used.

In conclusion, basic dyes and sulphur dyes differ in their chemical structure, dyeing mechanism, color fastness, environmental impact, pH sensitivity, fiber compatibility, dyeing process, and cost. Dye Manufacturers in India, Understanding these differences can help determine the appropriate dye to use for a particular textile material, color, and desired outcome.

What is the importance of Vat Dyes?

 

Vat dyes are a type of synthetic dyes that are known for their excellent wash and light fastness. They are commonly used to dye cellulose fibers, such as cotton, as well as some protein fibers, such as wool. Vat dyes manufacturers in India can produce a wide range of bright and vibrant colors, including blues, greens, and reds.

Vat dyes are called so because they are reduced to a soluble form known as a "leuco" or "vatting" form before being applied to the textile. Once the dye is applied, it is then oxidized to its insoluble form, which is then trapped inside the fiber. This process is known as "vatting" and is often done in an alkaline solution, which helps to improve the colorfastness of the dye.

The process of vatting can be done using several different methods, including the traditional method of fermenting indigo plants to produce indigo dye, as well as more modern chemical methods. Indigo is the most well-known vat dye, and it has been used for centuries to dye denim fabric.

Vat dyes are commonly used in the textile industry, particularly for denim and workwear fabrics. They are also used in the production of household goods, such as curtains and upholstery. Additionally, some vat dyes are used in the paper industry to color paper.

It's important to note that vat dyes can be hazardous to handle and use, and proper safety precautions should be taken when working with them. Additionally, different vat dyes have different properties, and it's important to choose the right dye for a specific application to ensure optimal color performance and durability.

WHAT ARE THE IMPLEMENTATIONS OF PIGMENTS?

Insoluble colourants in fine powder form are called pigments. The colour of pigments is altered by selective wavelength absorption through light transmission. They can either be organic or synthetic. They function as colouring agents in several sectors and offer protection from rust and corrosion. The unique qualities that make pigments, often referred to as colourants, the ideal colouring agents, are contained in them. Moreover, they give materials durability and stability.

It would be great if you did not mix colours and pigments. Both of them are very different. A colourant is stable in its non-liquid form at room temperature and has a high tinting ability. The cost and the way a colourant uses its physical features and properties will determine which one is best for a given application. Corrosion and colourants are where the phrase "rust stimulators and inhibitors" originated. Rust inhibitors have the least corrosive effects, while rust stimulators promote more corrosion. Inert colourants are those that exist between these two groupings. In colourants, selective light absorption occurs. When a colourant molecule is exposed to white light, various absorption processes take place. 

Organic colourants are composed of conjugated systems of double bonds that absorb light. Light absorption takes place by electron transfer in inorganic pigments. The appearance of colourants is affected by the spectrum of the incident light. For instance, a colourant would not appear to have the same colour under sunlight compared to fluorescent lighting. The colour difference will appear because a different range of wavelengths is left to be reflected. The colour, saturation, and other colourant properties depend on other compounds that go along it in products, such as binders or fillers. The most commonly used colourant is a green pigment. The pigment application of the green colour is manifold and is used in various industries and manufacturing units.

Application of Green Pigments 

Plastic Dyes applications and masterbatch

Colourants are substances added to the polymer base to give the plastic its colour. These substances can be either organic or inorganic. Colourants not only give plastics their hues, but they also affect how easily they can be processed, how long they can endure, and how compliant they are. The utility of plastic items can suffer from exposure to natural and artificial light. Therefore, UV protection is required for polymers used in outdoor applications. Green pigments shield things from the sun's damaging rays and other negative consequences. It aids in preserving the vibrant, vivid colour of the items manufactured with green pigment. The goal of transparency in colourants is to minimise the size of the colourant particle size. The size reduction is accomplished by layering around the newly generated particles to prevent crystal formation. For colouring agents that must have great transparency, transparency is advantageous. Additionally, they have the advantage of being spread out easily. A masterbatch is a strong combination created by evenly distributing colours and ingredients.

Utilisation Of Colorants In The Following Masterbatch Types-

White Masterbatch: White masterbatch is used in businesses and production facilities. It is utilised in blow moulding, injection moulding, thermoforming, laminating, coating, pipe, protective film, and fibre and non-woven materials.

Black Masterbatch: In polypropylene, polyethene, and universal carrier systems utilised in thin films, thick films, and more, a black masterbatch is used.

Color Masterbatch: Plastic resins undergo considerable alterations as a result of colour masterbatches. Additionally, it has numerous uses in industrial machinery for home appliances, textiles for packaging, designers, etc.

Additive Masterbatch: Masterbatches with additives halt degradation. It is utilised in packaging, consumer goods, transportation, agriculture, and building and construction.

Aqueous Ink Applications

The market's safest and most effective inks are aqueous ones. They work perfectly in workplaces, homes, and schools as well as for large-format printing. The highest-quality inks on the market are aqueous. They offer excellent colour depth for everyday use. Writing on adsorbents like cardboard and paper works best with aqueous inks. Aqueous inks are frequently made with blue and green colourants. The green and blue colourants' properties that are listed below aid in the creation of aqueous inks:

• The distribution of small particles

• They exhibit great transparency.

• High-quality purity that is resistant to sunlight is offered by them.

Coating Applications

Pigment Green 7 is mostly used in coatings and building supplies. It is acceptable to employ green colouring. Paint, plastic wallboard, and bricks are all examples of construction products that use the colour green. The green colour is extremely advantageous for usage in construction materials due to its great weather resistance. In the clothes-dying industry, green colourants are used extensively. The UV and solar resistance of the green pigment. The green pigment's lightfastness property makes it difficult for the substance to rapidly lose its colour. Additionally, it is utilised in the ink, varnish, and paint industries. For example, pigment green 7 should be used if you wish to create green ink for a printer cartridge or to reload your ballpoint pen ink. Why? The brightness is not a need for colouring agents, is the answer. They need opacity and toughness. You'll get opacity and durability from the green 7 colourants.

Various Other Uses for the Green Pigment

The Plastic Pigments Manufacturers, a pigment made by the same company. Additionally, it can be used in transparent conductive films, antistatic products, cosmetics, etc. It is simple to dissolve the green colourant with alcohol or water. Additionally, it can be blended with other inorganic colourants, acrylic resin, or any other kind of vehicle to make the colour opaque and durable.

The brightness, concealing ability, and tinting intensity of the green colourant are all quite good. Additionally, it is very resistant to outside weathering and chemical stability. It is particularly useful in many different industries and production facilities due to its excellent motion picture, coating, and adhesive qualities. Without colour, life would be drab and monotonous. It enhances our lives with joy and light and improves their visual appeal!

Conclusion

Different areas of textile dyeing and printing use pigments. It must therefore have some solid standards. Veeraco is renowned for the calibre of its high-performance pigments, which may be employed in a variety of difficult applications, from automotive coatings to fibre-grade masterbatch applications. Customers who buy products using pigments typically do so through stores or Plastic Dyes manufacturers of India. The founding year of Veeraco Colourants Private Limited was 1952.
