Acid dyes are anionic water-soluble dyes that are used to alter the colour of fibres like silk, wool, nylon, and modified acrylic fibres from neutral to acid. The salt formation between anionic groups in the dyes and cationic groups in the fibre is credited with at least part of the attachment of the dye to the fibre. Water-soluble acid dyes do not affect cellulose fibres. Acid dyes are used to dye protein/animal fibres such as wool, silk, mohair, angora, alpaca, and some nylons and synthetics.
These are the hydrochlorides or salts of organic salts also recognized as the cationic dyes which react with the negatively charged material. Categorized under synthetic dyes they are insoluble in water but soluble in alcohol and methylated spirit. However, the color base can be made soluble in water by transforming the base into salt. Basic dyes are optimal for dyeing plastics, dyeing paints, dyeing paper products, coatings, stains, industrial products, etc.
These are the alkaline dyes that can be detached into positively charged ions in the aqueous solution. There is an assortment of dyes under this range to meet the brightness and fastness requirements for a variety of end uses. Acetic acids are utilized in the dye bath to help absorb dye onto the fibre. They are also convenient for the coloration of paper.
Daylight fluorescent pigments are known for their outstanding brilliance, strength, and clean shades. We own a range of attractive shades that can be used for multiple applications. They are in much demand due to the outstanding brilliance at times where long-distance visibility is required. Its performance depends on the bonds if it is physical or chemical, resin and dyes. In the plastic field, these are used in toys, sports products, packaging materials, safety helmets, etc. We also serve products needed for textile printing, paper coating, paints, candles, and poster colours.
Disperse dyes are organic material that does not have an ionizing group. Disperse dyes are used to colour synthetic textile textiles since they are less soluble in water. Polyester fibre yarn is dyed largely with disperse dyes. Used dyes, on the other hand, are a reaction that occurs when cotton or cellulosic fibres are dyed.
Food colours are hues that have been chemically produced. Food colours were created as per international food colour quality standards. Our food colours are widely used to enhance visual appeal to a wide range of food and utility products. Food colour is any dye, pigment, or substance that gives colour when added to food or drink. Food Colours are supplied and exported in a variety of forms, including liquids, powders, and granules.
It acts as an additive imparting brightness in polymers and intensifying the degree of whiteness. They tend to soak up light in the UV spectrum and discharge light in the blue region of the visible spectrum to get a brighter and fresher appearance to the plastic. Optical Brighteners are often used in engineering plastics like polyvinylchlorides (PVC), styrene homo, and many other copolymers.
Pigments are a type of colourant that differ from dyes in multiple ways. Its primary work is to add colour to various materials ranging from cosmetic products to industrial equipment and paints. The after-effects of pigment can be both temporary and permanent. Organic pigments are used in food items, drugs cosmetics, stains, etc. While the inorganic can be used in automotive products, paints, cement applications, etc.
Solvent dyes, which are soluble in non-polar fluids and employed in a plethora of requests such as inks, plastics, and petroleum, are known for their versatility. These dyes are also utilised in the industrial cutting and automotive industries to colour metals. Purity, strength, solubility, and stability are all high in the distinctive variety we offer.
Its characteristics are mentioned in the name itself, these dyes are solvent-soluble organic metals exhibiting brilliant shades and excellent properties. They are soluble in almost all the solvents especially alcohol, ketones making them suitable for use in the metalized polyester film, metal foil lacquers, wood stains, shoe polish, inks, etc. They are available in powdered form and have long stability if stored properly in a right place.
Sulphur dyes are water-insoluble and must be transformed to a soluble (leuco) form with an alkaline reducing agent such as Sodium Sulphide (Na2S). Dark sulphur colours, such as blue, black, and brown, are common. It has a high production value and is widely used.
This class of dyes is classified by the method used to apply them. Vat dyeing needs a bucket or vat for the dyeing process. They have high colour fastness as compared to other dyes and are used for dyeing and printing on cellulose fibre and cotton.
