Dyeing is a method which imparts beauty to the textile by applying various colors and their shades on to a fabric. Dyeing can be done at any stage of the manufacturing of textile- fiber, yarn, fabric or a finished textile product including garments and apparels. The property of color fastness depends upon two factors- selection of proper dye according to the textile material to be dyed and selection of the method for dyeing the fiber, yarn or fabric.
The following figures illustrate with process flow diagrams the whole operation of finishing processes and how the dyeing process is a part and parcel of the process of textile making.
Seed Dressing IndustryThe main objective of coloring the seed dressings is used for marking and for warning reference. To avoid any sort of confusion and making sure that it does not end up being used as fodder. The most important colorant used here is red with typical concentrations of 600 ppm.
Crop Protection Industry Use of colorants in crop protection agents of the type insecticide and fungicides helps to clearly demarcate treated areas from the untreated ones. In addition, the dye stuffs also help in promoting safety in the handling operations.
Coloring of pesticides or herbicides is generally done by mixing chromatic pigments with dry powder formulations of the agents. Milori blue is a very popular pigment, that goes well with viticultural fungicides, other categories of pigments include lithol rubine, heliogen blue etc. Dyes used in the crop protection industry are Solvent dyes, Acid dyes or Basic dyes.
For bringing different properties like durability, resistance against heat and light reinforcement capacity etc., in the rubber products, different types of pigments are applied. Some of the pigments that are applied/used in the rubber industry are:
Organic Pigment Powders Used to develop other specific properties in the rubber made products. Titanium Dioxide Titanium Dioxide are used during the application process of rubber because these pigments have some good qualities. These good qualities are: high refractive index, consistency in the size of the particles, dispersibility, and high ultra violet ray resistance.
Carbon Black Carbon Black is a type of pigment which is derived from the refinery process of petroleum. In tyre manufacturing process, it is used for producing high resistance, abrasion and longevity and grip. Carbon black has wide variety of applications in different kind of rubber products. This range of rubber products starts from aerospace to ordinary household products.
Florescent Pigments Florescent is a kind of bright pigment and its powder form i.e. called as Powder Color is used in the rubber industry. This kind of pigments may be both organic and inorganic nature. The proper color selection depends primarily upon some requirements of the manufacturers such as: light stability, heat stability, resistance to bleed, resistance to migration and required shade.
Molybdenum Pigment Molybdenum Pigment is used in the Rubber Industry. These pigments are light, heat stable and having bright color range from bright red-orange to red-yellow. Apart of rubber products, these pigments are also used in ceramics, plastic, paints and inks. The other kind of pigments that is known as Ultramarine pigments, are also used for rubber products. These pigments have high heat resistance, light and weather resistance.
Bifunctional Organic Silicon Compounds The pigments which are used in the rubber industry, are generally bifunctional organic silicon compounds. These compounds have two reactive groups. For high quality rubber compounds, these pigments are used. When this kind of pigments are used in the rubber industry combined with sinaloan group-carrying pigments, then the effectiveness will become more effective.
Cadmium Pigments Cadmium pigments have no major application in rubber industry, but, for many minor purposes, these pigments are used in the rubber industry.
Zinc Oxide (Zinc White) as a Pigment Zinc Oxide is used in rubber industry since its inception.Some special properties of Zinc Oxide that make it popular for the rubber industry are:
Rubber - Metal Bonding Zinc oxide reacts with copper oxide for the bonding of rubber to brass.
Hear Stabilization Zinc oxide has a very high stability (resistance) of heat. So, when it is used for tyre manufacturing, then tyres become more stable and durable even at the high temperature.
Latex Gelation It gives enough stability in the gelation of foam, when latex foam rubber product is manufactured.
Pigmentation As zinc oxide has high brightness, high refractive index and proper particle size, so, when this pigment is mixed with rubber products, then the products will become more whitish.
Light Stabilization Out of all other white pigments, Zinc oxide has the maximum capability to absorb the Ultra Violet rays. So, when it is used with the rubber tyres, then the rubber tyres get extra stability to the destructive sunlight.
Now a days, the world market is flourishing with several new types of pigments that are used for coloring the glass equipments. In past, the various kind of impurities were responsible for producing colors in the glass equipments. For example, in the 17th century, in the 'black bottle glasses', the color dark brown or green was found due to the present of iron impurities. These impurities came in these glasses from two sources. One, and was used to make these glasses and second, sulphur from the smoke of the burning coal was used for melting these glasses.
But, today, the glass is colored by using various kinds of pigments (Purified metal salts). Some ancient examples of colored glass are: ruby glass (gold chloride is used as a pigment, invented in 1679), uranium glass (uranium oxide is oxide as a pigment, invented in the year 1830). It doesn't mean that, for every time, the colored glasses are useful. Sometimes, we need such glass, which is free from any color. At that time, we have to removed the unwanted color from the glass. The process of removing the color is called as Decolorizing process. Some commonly used decolorizing agents are: Manganese dioxide and Cerium Oxide.
Special Effects in Glasses By Using Pigments Special color effect can be generated in the glasses by using some pigments either individually or in the combined form with other types of pigments. For example, Iridescent glass (Iris glass) has a special coloring effect. This coloring effect in the iris glass can be generated by adding some metallic compounds (pigments). Sometimes, the coloring effect, in the iris glass can be generated by spraying its surface with lead chloride and then heating it in the present of reducing agent. Another colored glass is Dichroic glass. From different angles, the color in the glass seems to be changed. This is happened because, a very thin layer of colloidal metals (gold or silver) is applied on the surface of the glass. Some pigments and their coloring effects in glass
Some Usable Pigments in Glass Industry
Sodium Antimonate Sodium Pigments are also used as a decolorizing agents in the glass industry. These pigments are used as a refining agents.
Nickel Inorganics Pigments Nickel Inorganic Pigments are used to add colors, enhance the strength in the end glass products, and some other features in the glass products.
Cobalt Inorganics Pigments Cobalt inorganic pigments are used in various applications. These applications vary from adding colors, increasing strength to produce finished glass products. Antimony Trioxide (Sb2O3) These pigments are also known as White Pigments. These pigments are used in the glass industry as decolorizing agents. To remove the unwanted colors from the glasses, these pigments can be used. There purification capacity is very high and free from all types of impurities.
Factors in Selection of Pigments
Color is an integral part of the plastic material and it should not be considered as an after thought. The whole system of coloring has to be deal with using what is called a total systems approach. No doubt the color enhances the functionality, but it has also the potential to degrade certain material properties like impact strength, if not applied properly.
The colorants that are used in the Plastic Industries can be both the dyes and pigments. Both dyes and pigments exhibit color through the process of visible light absorption and scattering. Typically color formulations generally have four colorants. Black and white are used basically to control the value and Chroma, while two colored pigments or dyes are applied to establish the Hue.
Dyes that are used in the plastics industry must be very strong, show good heat stability and be transparent. Typically the dyes are used to tint or shade a resin. In the plastics industry dyes are limited in use, as such they can be used for only a selected number of resins. Pigments used in this industry can be organic or inorganic. While pigments offer more choices to the manufacturers due to its opacifying ability, broader chroma range, and better heat stability for most of the resins. Pigments are generally dispersed within a resin matrix, while dyes solubilize in the resin. Titanium Dioxide is a pigment that has a wide use in Plastics industry. It is used to make the plastics more whiter, brighter and durable.
Dyes or Pigments? A base polymer dictates the choice of the colorant selected. Pigments are typically used in polyolefins as most of dyes show a tendency to migrate in polyolefins. While Dyes are often successfully used with polycarbonate, polystyrene, acrylic, and other types polymers because of their color strength and transparency. The final word is whatever be the colorant selected it must show compatibility with the base resin. This is in order to prevent a color shift occurring over time.
Have a look at the properties of few of the colorants that constitutes both dyes and pigments:
In water-based inkjet inks there is presence of volatile organic compounds (VOC) and they do have low level of toxicity, the dry rate is relatively slow on the non-absorbent substrates. They often require a special coated media for optimizing dot gain and drying. They also need lamination to secure water resistance. Originally they were developed for the desktop systems only but moved on to facilitate the growth of inkjet in wide-format graphics.
Pigments give environmental friendly products along with durability and better compatibility with packaging. However one thing needs to be specified here is that the colloidal properties generally associated with pigments are more complex than dyes. Pigments for Water based inkjet printing Inorganic pigments Inorganic pigments that are used for making printing inks are Carbon Black (very important), Titanium Oxide, Molybdenum Red Pigments and iron Blue all with medium usages while Chromate Pigments (sparingly used). To make the white inks, the most important inorganic pigment is Titanium dioxide. Another popular inorganic pigment, calcium carbonate is used as an extender to make white inks. But, if we want to make black ink, then the most randomly used inorganic pigment is carbon black. Organic Pigments Now a days, the inorganic colored pigments are very rarely used because, these pigments contain very high degree of metallic toxics like chromium, cadmium and lead. In their place to create green and blue shades, phtalocyanine pigments are used. For red and yellow shades inks, Azo pigments are very preferred medium. Whether the molecules of the pigments will absorb light in the visible range or not, depends upon the presence of the conjugated system of double bonds in these molecules.
A few type of Pigments that are used for colored printing inksAdvantages- Pigments are tiny combinations of a variety of molecules. They are much bigger in size than their dye counterparts. This size advantage translates into:
Color Tinting System: A New Way to Impart Colors

A dye is a natural or an synthetic substance that has an affinity to the substrate to which it is to be applied. It can add a color or can change the color of any substance. The dye is generally applied in an aqueous solution and requires a mordant to improve the fastness of the dye on the fiber.
What is the difference between Dyes and Pigments? Dyes and Pigments have different properties and are used to create different effects. Both dyes and pigments appear to be colored because they absorb some wavelengths of light more than others. In contrast with a dye, a pigment generally is insoluble, and has no affinity for the substrate. These are mixed with oil, water, etc. to make paint.
Pigment is the natural coloring matter of animal or plant tissue. Pigments are used for coloring paint, ink, plastic, fabric, cosmetics, food and other materials.
What are hinges? Hinges are made of special archival tape, linen, or fine Japanese paper. With pressure sensitive tapes, prints cannot be glued or taped directly to a backing and for this purpose, hinges are used.
How does particle size affect a pigment's dispersibility? he sizes and shapes of particles of pigments have great impact on the colors of these pigments. But, these pigments are available in cluster form instead of individual form.
What are the lightfast properties of the pigments? The resistance characteristic of pigment against the fading after exposure to sunlight, is called as lightfast property of the pigments.
What are Pigment Sticks? Pigment Stick is an oil stick that transform oil painting into a whole new experience. These sticks consist of linseed oil, natural beeswax, and pigments. Generally, pigment sticks are highly fluid and very smooth.
What is the meaning of Luminescence? Luminescence is emission of light by a substance not resulting from heat; it is thus a form of cold body radiation.
What is the meaning of Fluorescence? Fluorescence is the emission of light by a substance that has absorbed light or other electromagnetic radiation of a different wavelength.
What is the meaning of Phosphorescence? Phosphorescence is a specific type of photoluminescence related to fluorescence.
What is the meaning of Brightness? Brightness is an attribute of visual perception in which a source appears to be radiating or reflecting light.
How does TiO2 provide opacity? When all of the visible light that falls on a surface, is scattered, then only opacity is appeared. Titanium dioxide is considered as an efficient light scatterer.
What is the relationship between Phosphorescence and Temperature? The light discharged by a phosphor, hugely depends upon the temperature.
Which chemical and physical factors affecting the light fastness of pigments and dyes? The lightfastness of the pigments and dyes do not depend upon the pigment or dye, but depends upon the whole system. These following factors affect the light fastness of pigments and dyes:
What makes one grade of TiO2 different than another?
The particle size and surface treatment make the grade of TiO2 different than another.
What are the prescribed directions while using dry pigments? For methods of using dry pigments (or other non-colored powdered additives) which require only as much mixing as is possible with a brush. These methods can be applied for solvent or water-based paints.
Will the organic color pigments stain the clothes or sheets? The color organic pigments are not stains nor these are dyes. So, if some stains arise in the clothes or sheets, then after some time these can be washed-out completely from any synthetic materials. These stains can be removed very easily.
What is a mixed metal oxide (MMO)? MMO is a kind of inorganic pigment that contain more than one types iron metals in their oxide crystal structure.
A multibillion dollar industry that consists of Dyes, Pigments and Intermediates. In Global Dyestuff industry, an impressive growth has been seen over the years. This industry includes three sub-segments namely Dyes, Pigments, and Intermediates. The dye intermediates are essential derivatives of petroleum products which after further processing gets transformed into finished dyes and pigments. The dye and dye intermediaries industry is now an integral part of a huge number of industries. Be it chemical, of which it has a substantial stake, along with that it also provides inputs to a large number of other major industries like textiles, leather, plastics, paints, paper and printing inks, pharmaceuticals to name a few. The following diagram highlights how the Dyestuff industry's interconnection with other facets of the industrial setup:
In 2005, the global market size for dyes, pigments and intermediaries was estimated at around $23 billion. If we see the total volume, then global dyestuff production is estimated to be somewhere around 34 million tonnes. The annual global sales of textile dyestuff alone is estimated approximately around $ 6 billion. One of the major factors that had emerged within the last few years is that the major production centres for dyestuff has shifted from the west to the east. The global dye manufacturing industry originally dominated by suppliers from Europe namely UK, Switzerland Germany, has shifted to Asia over the past 20 years or so. This is primarily because of two reasons. First, due to much lower costs of production in the Asia region. Secondly Asia's growing prominence as the hub for global textile industry.
Major challenges facing by the Global Dyestuff Industry Though an impressive growth has been seen in Global Dyestuff Industry, but still this industry is facing some serious challenges. And these challenges are:
Environmental Considerations- The thrust is now towards the environment friendly natural dyes.
Support of the Government and Trade Association- Any industry that moves ahead needs the back-end support of the government as well as the trade associations.
Problem of over capacity but falling margins- It is a fact that China and India now have high potential as regards production capacity is concerned.
Fierce competition- Again, because of the shift of companies from West to East has resulted in concentration of all the companies in the Asian region which has created intense competition in the global market.
Research & Development- Market demands a higher spending for innovation in products like natural dyes.
Product quality vis-a-vis competitive prices- Manufacturers should focus on the quality of products along with competitive prices for retaining market.
Classification of products and services- A decline in the growth for products has prompted the manufacturers to move to specialty products.
High cost of energy and interest- The exorbitant cost of interest can lower the investment in R&D which is at the core of product and service innovations. Also, the high energy cost has also adversely impacted the manufacturing units.
